• Reclaim free space after deleting Partition Bootcamp

  After installing a new SSD and gives back to the top of time Machine, I deleted my Bootcamp partition on my MBP using Boot Camp Assistant. The Boot Camp partition, although MS-FAT was no longer bootable after recovery, and I thought again and use Winclone to retrieve my Windows backup.  The result of delete Boot Camp seems good:

  XXXs-MacBook-Pro: ~ the name list $ diskutil

  / dev/disk0 (internal, physical):

  0: GUID_partition_scheme * 960,2 GB disk0

  1: disk0s1 EFI EFI 209.7 MB

  2: Apple_HFS Macintosh HD 959,3 GB disk0s2

  3: disk0s3 Apple_Boot Recovery 650.0 MB HD

  But when I look at the storage, I find that I went 113 GB on my hard drive MacIntosh partition (or says my Time prior Machine backup) to more than 300 GB.  The Boot Camp 118.5 GB partition is gone, but the 'Other' segment seems to have increased to 284 GB.

  

  I see a lot of solutions online for free space recovery after the removal of Boot Camp, but they do not seem to apply to me.  Many are for removals of Boot Camp failed using disk utility.  Several involve CS, but I have no basic storage.  I tried to boot into recovery and repair.  I tried several reboots to clear space.

  Any ideas, please?

• Partition question - what would be the best way to increase its space and take part of the space from another partition

  Hello, I have my 500 GB SATA broken down into 3 partitions. Vista and 2 others. The problem is the process of using Partition Magic, Vista has been given only 30 GB, now its operation with 1-2 GB of free space. I want to know what would be the best way to increase its space and take part of the space from another partition, but I don't want to have to reinstall or do I want to lose all the data like photos, browser, documents and news ect.

• How to check the space on the asm and raw device?

  Hi all
  
  I want to know how to check the space on the device of the DSO.
  We use a feature of the asm, which is on a raw partition.
  Our archive is full. I need to check the space on asm archve partiotion.
  How can I check the destination space archive?
  We are using partition raw device for crs and voting system.
  How can we check the space on the raw device and how do know us which device is currently in use and are not in service
  
  Thanks in advance

  4 - 5 raw partitions...
  What version of oracle?
  Install the OCR + VOTE in gross unit better than OCFS2. If you use 10g to 11 GR 1 material.

  If use 11 GR 2, take the OCR + VOTE in ASM disk group.

  You can check what raw OCR device:
  $ ocrcheck

  VOTEDISK:
  $ crsctl query css votedisk

  On 10g if using the raw device for OCR + votedisk: recommend 1 file = 250M
  11g recommend 1 file = 512M

• Add more space to the ASM disk group

  Hi all

  I am new to the DBA role and also in a process of learning. I need your help in putting a space at the ASM disk group. My VMware admin will add disk space to the virtual machine, and then the Linux admin will add space on Linux servers. Finally, I think I need to rebalance the database disk group to view the extra space. I'm not sure of what all the steps involved in this process. I like to read the Oracle Documentation, but I'm blurry and hesitant. Please let me know the steps to follow to add the ASM disk group space.

  We use

  Oracle DB version 11.2.0.3.0

  Linux version: 2.6.18 - 238.12.1.el5

  Thanks for your help

  No....

  You don't need any instance restart. More when you add a disk to a diskgroup, all rac nodes can see.

  I understand what you say, I have created a disk of asm with 500 MB of size using asmtool, so I can't resize using asm instance.

  1. What is the use of asmtool-added option, we can add an existing using this command drive space?

  This isn't for adding space, but it adds the label to the disk partition...
  asmtool - add \Device\Harddisk1\Partition1 ORCLDISKASM0
  >

  2 can you please explain this more, * it could be increased if you already held 300 total asm 500 disk space *?

  Think like OS, you have created a 10 GB partition for disk D:\ example. And now, you create files/folders with size of hugh (as some movies ;)) to drive D:\, so eventually your drive D:\ will fill. This is the case even with your asm disk, once you have used all your available space of the asm disk (that you created through asmtoll), you can not increase.
  By asmtool - create D:\Asm_disks\disk3 500, you assign the total size to 300 from the asm disk. Just as you add 10 GB partition for OS...

  You come to the backup from my point of view: it could be increased if you already worked 300 asm disk space total 500

  I have created the disk with the following text:
  asmtool - create 500 D:\Asm_disks\disk3 > size is 500

  I create diskgroup with
  SQL > create diskgroup DB 'D:\Asm_disks\disk3' size disc 300; > Here I wll use only max 300 size of 500 total. So once I get to the threshold of 300, I can increase the asm disk up to 500.
  As
  SQL > alter diskgroup DB resizing disk "D:\Asm_disks\disk3' size 500; > Increasing up to 500

  Default if the clause you SIZE omit while creating a diskgroup, asm then disc occupies all the available space of the device that you have created by asmtool

  >

  3. What is meant occupation here, not here where we can control the right of occupancy?

  We can control as I explained.

• Tablespace in theory of the ASM

  Hi gurus,

  In noASM of the instances of the file limit of data default to 32 GB and 32 TB to bigfile.
  So, my database a 500 GB and no use bigfile and I created 17 datafile for that.
  What unlimited specs on the creation.
  
  Server scenario:
  / data = 1 t (data)
  /data2 = 1 t. (index)
  
  
  I have the same space, partition on a diskgroup in ASM instance,
  
  
  Server scenario:
  DiskGroup + data = 2 t
  
  Its necessary to create 17 logical data files in the ASM instance or a data file with the unlimited clause?

  = Environment details end =.

  We have a 2 node RAC cluster.

  We wanted to add 2 LUNS to our data Diskgroup and asked team storage available to both nodes of the cluster.

  After that they provided, the Linux Admin scanned the LUN and powerpath device names were generated. The powerpath device names like SCSI logic unit number names are incremented sequentially. Because, two additional powerpath LUN used to Node1 to a local file system, the names of powerpath were incrementing differently in the two nodes.

  Thus, for the same LUNS emcpowerpath names differed in Node2. Linux Admin did not notice this difference. And he told us the names of newly added from Node1 LUNS powerpath that have been

  / dev/emcpowerv

  / dev/emcpowerw

  But in Node2, the same LUN were appointed

  / dev/emcpowert

  / dev/emcpoweru

  The DBA guess powerpath name these 2 LUNS will be same on Node2, label the discs to help

  oracleasm createdisk DATA17/dev/emcpowerv1

  oracleasm createdisk DATA18/dev/emcpowerw1

  After marking in node 1, the DBA ran scandisks in Node2. But while the oracleasm scandisks in Node2 is running, it does not seem to/dev/emcpowerv and/dev/emcpowerw in Node2. Instead, ASMLib is smart enough to read the LUN ID in Node1 and search devices powerpath with the same LUN ID and labels as Node1. What's it like in Node2, / dev/emcpowert is labeled DATA17 and/dev/emcpoweru is labeled DATA18 correctly, as shown below.

  / dev/emcpoweru

  DATA18

  Confirmed using the oracleasm querydisk Pei/dev/emcpower < x > .

  During labelling using the oracleasm createdisk , since we use the LUN name I always thought that asmlib dealt only with the names of devices (Powerpath name in this case). I didn't know that ASMLib treats ID LUN. If ASMLIB faces in LUN ID internally, then you don't need to have the same name for a particular LUN for disks shared in different RAC nodes? Right?

  ASMLIB contains 3 packs. Oracleasmlib, which is distributed under a license of Oracle user space and is not part of the standard GPL software distribution. Oracleasm-support, which is in the standard repository and kernel driver of Oracleasm, which is included in the core Oracle UEK only or distributed by Red Hat to RHCK kernel. The subsequent RHCK driver requires a Red Hat subscription. You need all 3 installed packages.

  ASMLib doesn't care to the SCSI ID or device names. When you configure a device to ASMLIB, he writes a header special disk in the device, the command scandisk read and identify a device. ASMLIB devices are populated under the tree of device/dev/oracleasm and found by ASM using the default ORCL: device chain.

  Don't forget that ASMLIB does not work with multiple devices and if you use DB-Multipath or EMC Powerpath, you need to blacklist the physical devices so ASMLIB will use powerpath or multipath device instead. Otherwise there will be no failover devices like ASMLIB will simply use the first device found and ignore the other. Check the following:

  Hello

  • REQUIRED_MIRROR_FREE_MBindicates the amount of space that must be available in a disk group to restore full redundancy after worse failure that can be tolerated by the disk group. The amount of space shown in this column takes into account mirroring effects. The value is calculated as follows: for normal redundancy disk group, the value is the total gross space for all disks in the largest group of failure. The largest group of failure is the one with the largest total raw capacity. For example, if each disc in its own group of default, the value would be the size of the largest capacity disk. For a disk group high redundancy, the value is the gross total space for all disks in the two largest groups of failure.
  • USABLE_FILE_MBthe amount of free space, adjusted for mirroring, which is available for the new files to restore redundancy after a disk failure. USABLE_FILE_MBis calculated by subtracting REQUIRED_MIRROR_FREE_MB from the total free space in the disk group and then adjusting the value of mirroring. For example, in a normal redundancy disk group where by default the mirror files use disk space equal to twice their size, if there's 4 GB of usable file space, then USABLE_FILE_MB is equal to about 2 GB. You can then add a file that is up to 2 GB in size.
  • FREE_MBis the unused capacity of the Group disk in megabytes, without taking into account any imbalance data. Therefore, there may be situations where the value of the FREE_MB column shows unused capacity but because one of the ASM disks is full, database entries fail because of the imbalance in the disk group. Make sure that you initiate a manual rebalancing to force the same distribution of data which translates a precise presentation of the values in the FREE_MB column.

• Configure the ASM without ORACLEASM drives

  
  Guys,

  I found that right for your perticular kernel asmlib is a PAIN. (I also came to know Oracle dsnt predict asmlib rhel 6)

  Finally, we can find those, but can any 1 share knowledge how to configure the asm without Asmlib drives?

  I mean I dnt want to use/usr/sbin/oracleasm createdisk/dev/sdb5 (like this)

  Now if you ask me what operating system, my OS is RHEL 6.3, but I would like to know for all versions of configuration asmlib.

  DB: 11.2.0

  Which records exactly? Local? NAS? SAN? Single path of I/O? Multiple I/O paths?

  The Linux kernel will automatically enumerate all devices h/w - and udev to create entries of device for these devices. Then all devices scsi for devices SAN/NAS/local lands in tree in/dev automatically.

  However, the device names are not static (not even local devices as a new drive added to the server may have an impact of the names of existing devices). So in general, the names of devices directly deprecated. Same fstab/etc/fstab of the kernel utilisΘ string of identifier.

  If you have multiple path i/o devices, the multipath driver should be used.

  If you have devices path of single e/s (e.g. NAS/iscsi), then you can do the following.

  1. Identify devices using lsscsi
  2. Use fdisk to create one (for example partition 4) partition on the disk, and then assign him da (Non-FSdata) partition type. This allows you to identify via the number of partition storage devices (i.e. all 4 partition are storage). The partition type is a safeguard against accidental to mount the partition as a file system.
  3. Create a udev rule to call for partition devices 4:
     file #: /etc/udev/rules.d/99-oracle-asmdevices.rules
     KERNEL == "sd * 4", BUS == "scsi"PROGRAM="/etc/udev/scripts/localdev.sh %b", SYMBOLIC link += "asm / $result", OWNER = "grid", GROUP = "oinstall", MODE = "0660" "
  4. Create a udev script that will create a special link to device ASM to ASM to use, for example

  #!/bin/sh
  # file:         /etc/udev/scripts/localdev.sh
  # descr:        outputs logical device name for a local asm scsi target
  
  TAG="[scsi]"
  BUS=${1}
  DRIVE=`echo "$BUS" |  sed 's/://g'`
  
  targetname=disk-${DRIVE}
  
  logger -t $TAG -- "/etc/udev/scripts/localdev.sh bus=$* target=$targetname"
  
  echo "${targetname}"
  #eof
  

  So when a partition device 4 is detected, a device entry is created for in/dev/asm. I used a very simplistic device (drive-busid) naming scheme. You can get the WWID of the device and assign more readable names.

  You now discovery point ASM string drive in /dev/asm / *.

  Once you enter the basics above (it is not that the resort), you can get very creative with how you want to identify the devices for ASM usage - and how you create and name (symbolic link) of the names of devices for ASM.

• Question of the ASM

  Hello
  
  I'll put up a 11.2.0.3 new install and I have a problem in my hands a little bit.
  
  While doing the installation, I created the asm on a partition disk in:

  oracleasm createdisk DATA /dev/sdb2

  Now, after rebooting, it may be the case when my score is not identified as/dev/sdb2 more instance cannot find the disc, so I need to tag it with something like

  e2label <partition> <labelname>

  to ensure consistent names after a reboot and my instance ASM will not fail
  
  My question is, can I I "remap" the ASM/dev/sdb2 < labelname > disc without having to recreate all over again? If so, how?

  DO NOT use oracleasm - as I have said, it is expected to be close to retirement. If you don't want to be related to it.

  Make sure that the device has the appropriate permissions before you start.
  In the installation program, select ASM for OCR. in the lower right corner to select CHANGE DISKSTRING and configured to point to/dev/sd * and he sees only one with the correct permissions. It will ask you the name of diskgroup, and you select the sdb2 with REDUNDANCY EXTERNAL device. It will automatically load the initial configuration.
