• Steps to move ASM orapw ASM on filesystem storage

  Hello

  Due to a problem found trying to even an EPS Data Guard from a RAC database, I need to move the password file of the instance of the ASM to the file system, $ORACLE_HOME/dbs.

  I did these steps.

  1. connect the user to network

  2 asmcmd > pwcopy + DATA/orapwasm /u01/app/12.1.0/grid/dbs/orapwasm

  3 srvctl change asm - pwfile /u01/app/12.1.0/grid/dbs/orapwasm

  srvctl config asm

  ASM home: < CRS Home >

  Password file: /u01/app/12.1.0/grid/dbs/orapwasm

  ASM listener: LISTENER

  ASM instance count: 3

  ASM cluster listener: ASMNET1LSNR_ASM

  I reboot the node and the ASM instance does not start.

  I ha dto to return to the old configuration:

  srvctl change asm - pwfile + DATA/orapwasm

  And at the back of the system until.

  someone knows I have done wrong?

  Thank you

  Arturo

  I do not understand why you are looking to "ASM file password" since Dataguard do not need. I think you need "Database password file" on the destination.

  If the target database password file is on ASM, then make a copy (and not move) on filesystem where Dataguard will be deployed and try again.

  See note MoS post previous post. It will help you manage this issue.

• The Group PS6100XS and Hyper-V Server 2012: migration of storage between LUNS corrupts VM

  Well, I'm puzzled! Summer hit my head against this whole week. Basically, ranging from a virtual machine clustered LUN on the Bay EqualLogic corrupts the virtual machine. Here is my configuration:

  1. SAN 1: PS6100XS 6.0.1 firmware, 2 LUNS configured as CSV, 1 as a quorum disk
  2. SAN 2: FreeNAS 8.3.0, 2 LUN (ZFS-formatted, for what it's worth)
  3. Server 1: Dell R310 running Windows Server 2012 with Hyper-V installed feature. 4 network cards: 2 made team for traffic LAN, 2 for iSCSI with HIT KIT 4.5 configured for MPIO.
  4. Server 2: Old box SuperMicro running Windows Server 2012 with Hyper-V feature installed. 2 network cards: 1 for LAN traffic, 1 for iSCSI with HIT KIT 4.5 installed
  5. Created and all cluster validation tests passed
  Here's what works:
  1. Ranging from a virtual machine of the LUN if there is no activity on the VHDX
  2. Move a VM all LUN the EqualLogic to any number of unit logic FreeNAS or vice versa
  3. Move a VM between LUNS on the FreeNAS
  4. Move a VM between LUNS on the EqualLogic BEFORE I created the cluster (just using Hyper-V Manager, not the Failover Cluster Manager)

  This is what kills the VM whenever:

  1. Create a virtual machine through the Failover Cluster Manager - is not matter which node owns the storage or the VM - tried all combinations
  2. Take an active virtual machine, power and move a LUN EqualLogic to another EqualLogic LUN. The move signals the success, but the VM blue screen at the end of the move will and will no longer be able to start. It's basically fried.

  BTW, I tried also to disable one of the iSCSI NIC on the R310 - what does not help either. Any ideas? I have a case goes with the support of Dell EqualLogic, but so far they have been puzzled. Anyone got something like this works yet?

  OK, after Dell tried about 5 different times to tell me that my setup was not supported (actually claimed that EPA software was not supported!) I finally got someone who gave me workaround: disabling ODX by changing the key "reg" HKLM\SYSTEM\CurrentControlSet\Control\FileSystem\FilterSupportedFeaturesMode from 0 to 1. This "fix", but it also takes one of the most interesting features of the 2012 Server + EqualLogic: ODX!

• Persistent ghosts - leakage of storage files.

  Hi people,

  I worked through a somewhat worrisome question lately: If you QFile.remove () a file that MediaPlayer plays or MediaPlayer.pause () or more recently MediaPlayer.stop () would be the file is deleted, but the disk taken up by the file storage to become available - never.

  The first time I came across this, I was perplexed: the total file storage to SD card used and free storage space don't add to the capacity of the card and there is no way to recover the lost space other than formatting the drive.

  I have also confirmed that it is not a thing of file system, but can also occur on the QNX6 file on the storage of the phone system. What happens when the phone storage is filled with ghosts files? You must do a security wipe!

  There seems to be two issues here:

  1. There is an easy way to remove the placeholder for the file in the file system that is not giving up the space used. (which can lead to the need to reformat your phone/card) I guess it can be considered a storage leak.

  2. There is no obvious way deleting a file that has been recently buffered in the MediaPlayer.

  Here is the output of command line I captured when the file _wasn't_ play:

  $ ls-l
  Total 105107
  -rw-rw-rw-1 devuser 1000_shared 53814712 Feb 08 19:23 sn0441.mp3
  $ df - kP.
  1024 - filesystem blocks used available capacity mounted on
  / dev/EMMC/user0 13826032 9625376 4200656 70%.
  $ df - kP.
  1024 - filesystem blocks used available capacity mounted on
  / dev/EMMC/user0 13826032 9572792 4253240 70%.

  You can see that 9625376-9572792 = 52584 k, is about the size of the file.

  If I do the same thing with a file that is at stake:

  $ df - kP.
  1024 - filesystem blocks used available capacity mounted on
  / dev/EMMC/user0 13826032 9625408 4200624 70%.

  > File is deleted the app here.

  9625408 - 9625376 is 32 k. ot anywhere near 96 MB.

  I can also confirm that this issue has been observed on the 10.0 and 10.1, 10.2.1.

  Has anyone else seen anything like this? I'd certainly appreciate advice on how to remove a file that has been recently used by the MediaPlayer.

  See you soon,.

  Eric

  Here's the response of the people of file system.  Hope this helps clear things upwards!

  By POSIX behavior, content of the file must not be released until all open in the file handles are released.  If we cannot free up space (stop for example), we will reclaim the space during startup for QNX6 file system.
   
  In the FAT formats, it's different because the file system has no concepts such as the names and the POSIX inode.  Emulate us the behavior in our implementation, but the lack of security features power means that it is possible to lose this space if the media is removed or system power off with the open file handles.  You can use the mass storage mode or place the card in a BONE to fill a control and correction of the host system.

• Development of Playbook (Qt4.8); app configuration data storage

  Hello

  I'm developing an application of PB using Qt4.8. I would like to know where I can store configuration data. The link http://supportforums.blackberry.com/t5/Adobe-AIR-Development/BlackBerry-PlayBook-File-System-Layout/... gives to think that the folder 'data' is mapped in $HOME

  This means that, in my app, I can simply copy config data in ' ~ / appConfig.dat ' (i.e. tilda oblique which is a unix convention to go to the home directory)

  See you soon,.

  "You can store configuration data in the app storage directory that can be accesed by using the access/accounts/1000/appdata path / namespace.application data.   You can also use system browser in the IDE to see the application directory structure.   I've included more documentation about this below.   Even if it's for BB10, most of the details also apply to the PlayBook.

• Automatically deleted from the storage of the DSO after data files using the command cp ASMCMD... why?

  I installed Oracle database on Linux 6.6, Virtualbox 11.2.0.1.0.

  I used ASM for database storage.

  When I want to perform a backup in offline mode. I stop the database data files and copy to the filesystem as follows (for example).

  ASMCMD [+] > cp +DATA/ora11g/datafile/system.270.883592533/u01/app/oracle

  The files copied with success and also any other data files, logs and controlfiles files. Then, I also rename all the files in editing mode.

  After that, I used the backup files to start the oracle of backup (storage non - ASM with new pfile edited)

  Open successfully from a backup database.

  But when I want to use old spfile to open the database for the storage of the DSO again, a few errors have occurred as no data files in ASM storage.

  I check the contents of the ASM storage with ASMCMD commands. And realize that there only spfile and controlfile located ASM storage and other files: data files and online redo logfiles automatically deleted.

  Why the data files and log files deleted ASM storage? Is this normal? I have no delete all files of the DSO.

  It is actually deleted from the use of the cp command?

  Exactly what we say.  Data in ASM files are OMF (Oracle managed files).  The RENAME translates the DSO by deleting the original file.

• / storage/core support missing

  I deployed a 3 x average cluster nodes and had run a few days before I started to notice a warning in vROPs that the storage has been insufficient.

  While they inspected the storage available in the monitor system LI for all 3 nodes and notice was one show only 7.3 GB of available compared to 233 GB on 2 other nodes.

  I ran the beam of support and research if the files I look at the df file and noticed that he was missing the mountains/storage/core and/storage/var from the node with the 7.3 GB available.

  I mode Mainteanance and restarted, node, but the mounts are not automatically returned.

  Is any way to restore?

  Is this a known issue?

• ESXi host has no persistent storage / fsUUID is null

  Hello

  The issue I'm having involves a HP N40L Microserver w / local storage on a HP SmartArray P410 controller.  6 hard drives configured in a RAID10 array and the multitude of ESXi what OS runs on local USB.

  A recent issue w / the matrix raid caused a crash of the VMS resident and now "host ESXi has no persistent storage" message.

  I solved the problems of disk HARD w / table (replaced a disk), and the table is presented in the peripheral topic under "HP Serial Attached SCSIDisk.  ID is naa.600508b1001c8d82bf5f4a33f0e2bc04

  However, the data store does not appear in the tab of data warehouses.  I refreshed and restarted several times w / no success.

  This data store was run on an installation 5.1 ESXi (ISO custom HP) for a few years without problem.

  To try to solve the problem, I installed ESXi 6.0 U1 on a new USB stick which fortunately is now running in the Microserver but presenting the same behavior for the data store.

• View Storage Tiering

  Hello, im a little new for VDI.  VDI is already in place and im picking up things.  Currently there is only one still deployed and we want to start using storage levels

  What we have

  5.5 vCenter

  Hosts Esxi 5.5 (5 guests)

  VMware View 6

  Storage

  Table of NetApp - there are 3 Flash SSD storage, each 1 TB LUN.  There are two 500 GB LUNS each of 15 k SAS Drives.  And three LUN 1 to each Sata storage.  We also have lots of Sata storage, we can add, if necessary, might be able to add more SAS is necessary.

  Ive been going about things and he uses is not Sata or SAS storage.  Here using only the SSD storage that worries me, because we rely on the addition of several pools and SSD is at a premium.

  We use linked Clones and currently, there are two pools.  Each cluster is a floating pool so no need to keep the data of the user and they refresh overnight.  A swimming pool is only 15 desktop computers and the other is 120 workstations.

  The two pools were a little Proof of Concept pools and its actually affected the production now.

  Moving forward the plan is to add more pools, maybe another VM 400, as of this moment the new VM would float pools so no need to keep the data of the user.

  I want to Storage Tiering as there is no budget to buy more storage SSD.

  I know that I can split the storage so that the replica on the SSD storage and the BONES and the other files are on a slower storage.

  So now, a few questions

  1. my understanding is replica should be on tier-1 (ssd), the operating system and other files can be on the slower storage, but it would take on SAS 15 k disk storage or can it be the slower storage Sata? I hope that Sata

  2 lets say, I find myself with 5 swimming pools.  IM assuming that I can have multiple replicas can on the same logical unit number? or should I be split my LUN by Replica?  This means that I have to cut my LUN differently

  3. There is a limit of about 128 VM per LUN, how it works during the introduction of Storage Tiering?  IM assuming that it is not serious, the replica would be on the SSD LUN and then the rest would go to the SATA or SAS LUN disks, and I could have up to 128 VMS on the Sata/SAS LUN?

  4. the VM per LUN 128 means that I could use the LUN more?  I currently have 5, but do not know if we will use the SAS LUN.  So I need to add a couple more Sata Lun?

  5. If best practices says 128 VM per LUN.  Currently my LUN is all the same Raid Volume.  Is how important it?  What is VMware says to split up the LUN because its assuming the LUNS will be on separate Volumes of Raid or just because of filesystem VMFS itself?

  Im going to be read allot more on VDI but I thought ide goto the forums first to see what think

  Thank you

  You need not split by replica LUNS. I would put all of your replicas on SSD, and yes they can share a LUN through many swimming pools.

  You'll just want to have multiple LUNS that helps to balance the pool (s) on. Create as many LUNS you want to spread things, but really thinking about time zones and IOPS / s. 128 is a guideline, but not a rule lasts. It's all about having enough IOPS / s to serve requests you will get during peak usage.

  I'd go with SAS if you can, but SATA is acceptable - just all this affects the user experience. Consider using SATA for task workers or people that do not generate a lot of use of storage. Trial and error and acceptance by the user would be good to come through here if you do not yet have.

• Using the odd drive with shared storage

  We have deployed a 15-node cluster with shared storage.  When we issue a df - h, we see the root filesystem and / mnt mounted file systems.

  We also see the file of each of the other systems the datanodes on the local storage of the each other.  For example...

  / mnt/SCSI-123abc is mounted on the server server01

  / mnt/SCSI-456def is mounted on server02

  Under/mnt on the server server01, we also see/mnt/scsi-456def under the root file system, not mounted as its own file system.

  Under/mnt on server02, we also see/mnt/scsi-123abc under the root file system, not mounted as its own file system.

  Is this a problem of storage configuration, or is this something that the BDE has decided when it deployed?

  Thank you

  Steve

  BTW, you can add your script hack or the scripts that I have provided in the /opt/serengeti/sbin/format-disk.py file in the node template, and then after that the empty cluster is created, the mount point/mnt/bigdata1... are there the/mnt/bigdataN.

• Storage of Mirage on ReFS

  Hello

  IWAS wondering if storage mirage could be deleted on a filesystem available since Windows Server 2012 ReFS.

  It seems that in ReFS, no disk check more is necessary and therefore, it can handle large data without error.

  Is that what have tested someone who?

  Thanks for help

  Well, Mirage requires a CIFS share which must support alternate data streams (ADS).

  So it does not really matter what is happening below file systems as is drawn using the CIFS protocol.

  This is the reason why it works, for example, with NetApp, HDS and so on.

  I really don't see why it shouldn't work if you share and access your ReFS partition via CIFS and it supports ADS but have not tested.

  See you soon,.

• Difference between ADVM Volume and filesystem ACFS ASM disk group

  Q1. What is the difference between an ASM disk group and a Volume of ADVM?

  In my opinion, an ASM disk group is actually a logical volume to the database (including the FRA files) files.

  11 GR 2 appears to have introduced the notions of volumes ADVM and filesystems ACFS.

  11 GR 2 ASM disk group can contain:

  • ASM disks
  • Volumes ADVM
  • Filesystems ACFS

  Q2. ADVM volumes appear to be dynamic volumes.

  However is it therefore not effectively overlaying a logical volume (the volume ADVM) under ASM disk group (conceptually a logical volume as well)?

  Even worse, if you left the ASM disk group redundancy in hardware RAID / SAN level (as recommended Oracle), you actually have 3 layers of logical disk? (ASM on top of ADVM on top of RAID/SAN)?

  Q3. If it is 2 layers of logical disk (i.e. on top of ADVM ASM), what makes this better than 2 layers using a 3rd party volume manager (for example the DSO at the top of the 3rd party LVM) - something Oracle encourages against?

  Q4. ACFS file systems, seem to be file systems clustered for not including ORACLE_HOMEs database files, application exe etc (but NOT GRID_HOME, OS root, OCR or voting records)

  Can you create / modify filesystems ACFS using ASM.

  The diagram of topology of oracle for ASM in ASM 11 GR 2 administration guide, says ACF in ASM. I'm not sure about that if ACFS belongs to ASM or ASM is located at the top of the ACF?

  Q5. Connected to the 4th quarter. There seems to be a number of different ways, ACFS file systems can be created? Which of this is the valid methods?

  • Thanks to ASM?
  • through native OS file system creation?
  • through OEM?
  • through acfsutil?

  my head explodes

  Any help and clarification appreciated

  Jim

  
  

  Q1 - volume ADVM is a type of special file created at the DG of the DSO.  Once created, it creates a block device on the BONE itself which can be used as any other block device.  http://docs.Oracle.com/CD/E16655_01/server.121/e17612/asmfilesystem.htm#OSTMG30000

  Q2 - the asm disk group is a group of disks, not really a logical volume.  It combines the attributes of both when it is used for purposes of database as the database and some other applications know how to talk about Protocol 'ASM '.  However, you won't find all the versatile applications that can do.  In addition, some clients prefer to deal directly with files and devices of volume systems which ADVM is forced to make.  In your thinking, you have 3 layers of logical disk, but each of them provides features and different attributes.  This is not a bad thing, though, as each has a slightly different purpose - os file system\device, specific database and storage-centric.

  Q3 - ADVM is specifically developed to extend the features of the DSO for use by General applications of BONE.  It includes the performance of database features and is tuned to work well in this situation.  Because it is developed in-house, it benefits from the design of ASM model.  In addition, rather than having to communicate with several vendors for support, your support is limited to calling Oracle, a single window.

  Q4 - you can create and modify filesystems ACFS by using command line tools and the ASMCA.  Creation and modification of logical volumes coming through SQL (ASM), asmcmd and ASMCA.  EM can also be used for the two elements.  ACFS is located at the top of the ADVM, which is a file in an ASM disk group.  ACFS is aware of the characteristics of the ASM\ADVM volumes and tunes it's IO make best use of these features.

  Q5 - several ways:

  1) connect to ASM with SQL, use 'alter diskgroup add volume' as Mihael points out.  This creates an ADVM volume.  Then, put in shape volume using the "mkfs" (* nix) or acfsformat (windows).

  (2) use ASMCA - a GUI to create volume and a file system.  Probably the easiest if your head is explosion.

  (3) use "asmcmd" to create a volume and 'mkfs' to put in shape file ACFS system.

  Here is information on the ASMCA, with examples:

• storage in XenCenter 6.1 problem

  Created a VM for Xenserver 6.1 in my 5.1 ESXi hypervisor.  No problem encountered.

  For Xenserver 6.1, I started with 16GB of virtual disk to install the Xenserver hypervisor on it.

  But in the 6.1 Xencenter, local storage shows 8 GB only. So now I can't create VMs on Xenserver because there is not enough room.

  Then I added a second VHD to Xenserver VMS 6.1 with 60 GB.  But in the Xencenter client there is no way I can see this storage.

  Not sure if I illustrate my problem clearly, looking forward to responses from users here while I work on this issue as well.

  Thanks in advance.

  This question should probably ask in a place that caters to XenServer.

• Migration of storage with RDM

  I images migration towards a new framework for storage. Things work really well, but I hit came across a few images which have been implemented several there are many moons with RDM. The kicker is that they are in physical compatibility mode, so I can't just migrate and convert them to a vmdk. Any thoughts on an approach to migrate? Only the approach that comes to mind is to use VMconverter. This would require a little time to stop, so I'll have to postpone this possibility. I have a lot more flexibility on when I can migrate images if I could use the motion of storage because it requires downtime for images. At least there are only a small number who fall into this category but are images that are among the largest disc attached to like 500G - 1 TB...

  Buck - I realize this post is old, but I came across it and thought I would fill you in on how to migrate LUNS RDM in physical compatibility mode.  I read so many messages saying it's impossible, but it's actually much easier than you think, but the virtual machine must be turned off.  Here's how:

  (1) log into the ESX console as root

  2) go to your virtual machine folder: / vmfs/volumes/vmfs-volume-freindlyname/vm-folder.

  (3) locate the pointer to your disk file, this isn't the file - vocation, it's the servername_1.vmdk, it's only a few KBs, inside he does nothing but point to the real disk file, which in this case will be servername_1 - rdmp.vmdk.  It is the file servername_1 - rdmp.vmdk maps of the e/s to the real lun which is still represented by ESX as something like vml.xxxxxxxxxxxxxxx and can be found in/vmfs/devices/drives.

  The source that you want to migrate (with this method, it is in fact a copy which is good, because the source is always left intact) can be a virtual disk, virtual rdm or physical rrdm, it is not «question, you will always use servername_x.vmdk as source file in the command string, you're about to see...»

  but before I continune, if you want to migrate LUNs compatibility mode physical to a new lun to physical compatibility mode, be sure to have configured the lun so that ESX can see.  If you convert virtual RDM of RDM physical mode, the same applies.  If you convert it to a virtual drive, just be sure to have a volume of vmfs with enough space to accommodate the new drive.

  (4) it is here:

  To migrate and convert physical RDM in virtual disk:

  vmkfstools-i servername_1.vmdk/vmfs/volumes/vm record/name of the server - newdisk_1.vmdk

  To migrate and convert physica RDM virtual RDM, there are two methods

  -in vi edit customer of VM VM settings, remove the drive mapped to vocation, off voltage then re - add a new hard drive by selecting the same disk make sure you only select virtual fashion, connect you and see all your data and mount points are the same.

  -from the ESX prompt in the folder of the virtual machine on the VMFS volume:

  vmkfstools-i servername_1.vmdk d rdm:/vmfs/devices/disks/vml.xxxxxxxxxxxxxxxxxxxxxxxx/vmfs/volumes/vm record/servername_1 - rdm.vmdk

  To migrate a new physical RDM physica RDM:

  vmkfstools-i servername_1.vmdk d rdmp:/vmfs/devices/disks/vml.xxxxxxxxxxxxxxxxxxxx/vmfs/volumes/vm record/servername_1 - rdmp.vmdk

  EXPLAINED command strings:

  vmkfstools-i is import-command clone

  the servername_x.vmdk is the source, the x will be held for the command of the unit, in my example I use this 1 which means that it is the second disc on the virtual computer.  the first disc file is servername.vmdk, it is generally always the system disk.

  the-d is the disc type for the destination you are converting to

  the rdm (p) is part of the type of drive saying the destination disk is gross, virtual or physical disk mode (the p stands for physics course)

  folder/servername_1 - rdm.vmdk/vmfs/volumes/vm tells us where to store the raw disk mapping file, I chose to put it in the folder of the virtual machine as you can see, you can put it on any vmfs filesystem, I like to keep things neat and clean.

  Hope you find this useful, don't let anyone tell you that you cannot migrate a physical RDM.  His false information.  This is how its done.

• Fix the OS for the NFS storage

  We test vsphere with NFS storage. We use CentOS 5.3 with exts and Fedora 12 with ext4 filesystem. At the time of the creation of the VM.

  It is grayed out options 'enable FT' & 'thin provision.  It seems that the NFS server is to select the VM itself hard disk space.  What operating system that we should

  use to fix this?

  Kind regards

  In this case don't you worry.

  You have thin disks.

  FT is not activated at the level of the disc (it is only a condition), cause, you must activate (if you need) at the virtual machine level.
