  The issue was due to wrong settings for the frames. This has been fixed by the storage team. T2P scripts were always initially and after that correction of the Storage mounts, they ran successfully. A restoration was necessary, and RCU patterns had to be recreated on the clone

• ESXi 4.1 - blades HP and NFS mounts

  Hello

  I'm having a strange problem with NFS access

  We currently use HP Blades BL680c G5 servers, in C7000 enclosures. Configuration of the switch, Cisco (3120 x) are the same for all ports / ESXs.

  I use VMNIC0 and VMNIC1 in etherchannel / Hash IP access to the warehouses of data NFS on NetApp filers.

  I have now two servers beside I want to reverse for test reasons. These two servers are moving instead of the other.

  Once restarted, these two hosts ar sees no no more data warehouses. They appear as inactive. I can't reconnect them (VI client or esxcfg-nas - r)

  vmkping for Netapp file servers works more also.

  As soon as I put these 2 servers to their original square, everything is back to normal.

  On the side of the cisco switch ports are still configured the same. None of them are closed.

  There I'm missing something, but don't know where to look.

  Thanks in advance

  Hi Hernandez,

  If you're repatching hosts or they always use the same network cables as before (perhaps a change of IP address, or a rule on the host of the NFS export)

  don't forget, you'll have policies created on the NFS mounts 'export' these fixtures for the names of specific hosts or IPs - if you're repatching and change IP etc you can cause this export invalidation,

• Questions of NFS mount points

  I have two questions about how the NFS mount points is in fact from the point of view NFS servers.

  If the mount point of the 'outside' is considered as for example / ISO, would this mean

  1. that the directory is named "iso" or could it be a real name on the local file system on the NAS Server? (As in the names of SMB share, could be different from the name of folder.)

  2. that the folder is actually located directly on the root of the local file system, which is/ISO on the server, or would it be for example/dir1/dir2/iso and always to the outside as appearance / ISO? (As in the SMB, where 'share' creates a new root somewhere on the filesystem that is exposed to the outside.)

  ricnob wrote:

  Thank you! It would be a typical NFS-Unix/Linux server?

  Yes.

  So perhaps it is not defined in the standard how this should be done, but can vary between implementations? (* nix of course most common.)

  Possible, but does MS ever meet standards? Even their own?

  RFC1094/NFS:

  "Different operating systems may have restrictions on the depth of the tree or used names, but also using a syntax different tor represent the"path", which is the concatenation of all the"components"(file and directory names) in the name...". Some operating systems provide a 'mount' operation to make all file systems appear as a single tree, while others maintain a 'forest' of file systems... NFS looking for a component of a path at the same time.  It may not be obvious why he did not only take the name of way together, stroll in the directories and return a file handle when it is carried out.  There are many good reasons not to do so.  First, paths need separators between items in the directory, and different operating systems use different separators.  We could define a representation of network Standard access path, but then each path must be analyzed and converted at each end.

• maximum size of the NFS mounts

  Hello

  I would like to know what is the maximum size for mounting NFS into ESX (i) 4? If I need more than 2 TB, I need to use extensions iSCSI volumes. Is it the same thing with NFS or I can come up and use for example a 4 TB NFS share?

  Thank you

  Marcus

  NFS mounts have No. limit.  It is also great that you need to make.  ESX can mount NFS, that's all.  The ONLY limitation for ESX is VMFS, because ESX creates / manages VMFS volumes.  NFS mounts are managed by OTHER systems, they have their own limits.

  NFS is just a huge disk hard as far as ESX is concerned.

• How to start vmware after NFS mounts

  OK, so now I have solved the mystery of editing.  I'm looking for the gurus of linux on how to change the sequence of boot for mounts NFS are made prior to the VMware service.

  I use Centos 5.3 on the host.

  Phil

  Hello

  You must configure vmware to start after nfs and network.

  A simple example makes it easier to understand:

  LS /etc/rc3.d/S*network

  /etc/rc3.d/S10network

  LS /etc/rc3.d/S*nfs

  /etc/rc3.d/S11nfs

  LS /etc/rc3.d/S*vmware

  /etc/rc3.d/S05vmware

  In this case, it may be like this:

  RM /etc/rc3.d/S05vmware

  ln-s /etc/init.d/vmware /etc/rc3.d/S20vmware

  Today, vmware always will begin after the nfs mounts.

  A saludo/best regards,.

• NFS mount options

  I just bought a Qnap NAS box that I want to share with 2 VM hosts.   I did a little research on NFS vs iSCSI and it seems that NFS has some pretty good advantage over iSCSI.  Especially when she is on a network to shared resources.

  The hosts are the two Centos 5.3.

  I wonder what would be the optimum settings (options) for the NFS mount?  I found a couple of some old site, but I wonder what people here use?  Here's a setting string that I found:

  nfsvers = 3, tcp, timeo = 600, TRANS = 2, rsize = 32768, wsize = 32768, hard, intr, noatime

  I'm heading to the coast to look at the man page for NFS now to see what these all mean...

  Thank you

  Phil

  Here's a good explanation of this thing:

  The nolock option prevents the sharing of file locking

  information between the NFS server and the NFS client. The server is

  unaware of the file locks on this client and vice versa.

  Using

  the nolock option is required if the NFS server has its NFS file lock

  the feature in a State broken or remained dead letter, but she works between

  all versions of NFS.

  If another host is accessing the same files that

  your app on this host, there may be problems if file locking

  information sharing is disabled.

  Failure to maintain good

  blocking a write operation to the same host with a read operation on

  another may cause the reader to have incomplete or inconsistent data

  (reads a structure of data/record/line that is written only in part).

  A

  locking failure between two writers is likely to have data

  loss/corruption, such as the later writing replaces the previous one. The

  changes made by the previous write operation may be lost.

• Cannot add NFS mounting

  Try adding that another NFS mount to a 3.5 server.  I have an existing one on a Windows 2003 server that fits very well.  The error I get when creating is:

  Hey fabio_brizzolla,

  Well the first thing I found was that the D - Link DNS-320 is not on the hardware compatibility list VMwares, however some other versions are, so unless I missed something I couldn't find it, which means that there could be unexpected behavior of the installation.

  Having said that, your other editing that are the same, they all work well on a 5.0 update x is just installing 5.5 that you are having problems with?

• Unalterable audit NFS mounted data warehouses

  Hi all

  I searched for a cmdlet or function that returns if an NFS volume is mounted read/write or read only on a node.  The use case for this looping through a vCenter to ensure volumes that need to be mounted read-only were not accidentally mounted read/write during a reconstruction of node.  I haven't found something that returns this value.

  Is there something available in PowerCLI who will provide this information?

  Thank you

  Jason

  Try something like this

  foreach($ds in (Get-Datastore | where {$_.Type -eq "NFS"})){    $ds.ExtensionData.Host |     Select @{N="DS";E={$ds.Name}},      @{N="RemoteHost";E={$ds.RemoteHost}},      @{N="RemotePath";E={$ds.RemotePath}},      @{N="ESXi";E={Get-view $_.Key -Property Name | Select -ExpandProperty Name}},      @{N="AccessMode";E={$_.MountInfo.AccessMode}}}

• Windows Server 2008 R2 NFS mounted data store is read only

  I've done this dozens of times in the past, but not with this exact combination successfully:

  ESX4 U1

  Windows 2008 R2 Server Datacenter edition

  NFS Server installed. TCP Version 3.

  The normal configuration that worked in the past:

  NTFS security - total control on ANONYMOUS logon, everyone control total

  The local policies, network access: Let Everyone permissions apply to anonymous users (applied automatically by Windows)

  NFS Sharing - ANSI encoding, allow anonymous access - UID = - 2, GID = - 2

  NFS share permissions - allow all THE MACHINES read-write, ROOT access

  The data store adds OK and appears in the list of data on vClient stores and can be viewed or directly via a Console logon.

  The problem is that the data store is read only! Nothing from ESX can write, delete, or update a folder or a file on the data store. Access Windows NTFS is very well.

  This means also you cannot boot from say a CD ISO on the data store, or create a VMDK guest virtual computer on the data store.

  Given that I had zero problems with this in the past, when with the help of ESX3 or ESX4 connect to Windows Server 2003R2 or several NAS with NFS devices supported I think Windows 2008R2?

  Has anyone seen anything like this before?

  I use it currently; It works fine, but it's the way that you configure the windows nfs export without having to use a mapping service (see images)

  Also, be aware that Windows System Cache is a bit less efficient than linux (but that's ok) you just need to add additional RAM at least 16 GB for the data store busy.

  I also recommend refining delays in setting up nfs for each virtual machine host:

  NFS. HeartbeatFrequency = 10

  NFS. HeartbeatFailures = 5

  And on windows change the properties of the NFS server in the locking tab

  customer collection lock wait 5

• Storage of P2V of NFS mounted in a virtual machine

  Hello

  I'm looking for the best method to achieve the following objectives:

  We currently have a Server 2008 R2 Virtual Machine with its operating system disk in the virtual environment (vSphere 5, ESXi 5 Update1). In this machine are two additional disks provided by our EMC SAN using Microsoft iSCSI Initiator in the virtual machine. This our main file server.

  We would like to take advantage of the software virtual backup we use (Veeam 6.1) so would to move these disks in the virtual environment as VMDK.

  I know that potentially we could create two new VMDK and synchronize the data across, but is there a way to clone those to preserve all the permissions, etc.

  Any advice would be appreciated!

  Thank you

  
  Dan

  It appears so, but I do not use Veeam Backup and replication, so I can't tell you for sure.

• How to backup without identifier (NFS vs SMB/AFP)

  Hello

  you just bought a ReadyNAS 312 but do not yet know about some basic principles.

  I want to use mainly as a backup destination, but also as the main source for backups Crashplan. In detail I will not install Crashplan headlessly on the NAS (totally not supported) but I prefer to install on my computer, which is then connected to the NAS through my line (just check, taken Crashplan supported files attached nas backups).

  What I don't understand is how can automatically make sure Crashplan can see the files at all times... I think that this should be easy with NFS and Linux computers. I just need to configure actions to be mounted automatically at each start-up, right?

  What, Mac computers, is even achievable with SMB/AFP so that I don't connect all the time in the Finder.

  I know that these sounds of questions a bit silly, but it's the first time I have use a SIN 'serious '.

  To be honest: sooner or later we will return only Linux boxes in the House, but at this point we can not yet get rid an Apple computer.

  Thanks a lot for any suggestion

  My initial confusion is related to how to automatically assemble the network shares on my system (the a CrashPlan possibly running) to make them available to the local backup software (which will take care to copy the files to the NAS)... Sorry for the bad wording or maybe you misunderstand something.

  http://support.code42.com/CrashPlan/latest/backup/Mounting_Networked_Storage_Or_NAS_Devices_For_Back... answers for OSX and links to a similar article for Windows. I suspect that for Linux, you simply create a NFS mount point suitable, but I have not tried. In any event, you don't really need to go with headless on the NAS installation, if it presents the advantage to avoid the need for a separate device.

  With Windows, the name of user and password may be different. Configure you in the Windows Credential Manager. I'm not a Mac guy, but I think that Keychain Apple does the same for network with OS x resources. I think that with Linux, you need to explicitly use the opening of session and password in the mount command (I don't think it's the equivalent of the Windows or Apple Keychain credentials manager).

  I have already subscribed to a (computer) personal unlimited plan, I can envision the family upgraded but happy enough to save a little money as well. I'll try to keep a couple of good games of local backup in the first place.

  Which is what I did. I have an unlimited plan for single computer for the NAS. I use Acronis image to back up the disks of PC 'C' on the NAS and also to use the SIN as a consolidated storage. I have 3 copies local of all (the primary account as a NAS) use and maintain CrashPlan as expensive disaster.

  My pro - 6 has 2 GB of ram, which worked well for a few years, but eventually unlimited retention of deleted files caused central CrashPlan CrashPlan to run out of memory. This is what prompted the request for assistance to Crashplan. The solution was to the retention value of the files deleted in 6 months and then consolidate archive. That took a while (Crashplan was not wise to this point). I've also increased the memory in the pro and CrashPlan defined to use the size of the memory possible max (which, on the pro, is about 3.5 GB with a 32-bit JVM).

  It has been working fine since that date (end of June). In any case, it's a good idea to lower the setting for the retention of deleted files. I also put deduplication to "minimal".

• Storage shared by NFS for RAC

  Hello

  I intend to set up a node 2 CARS. However, I have only the internal drive to use and no SIN /SAN. So I intend to share some of the ability of alternatives I have on the internal nodes 1 & 2 discs and make shared storage using NFS. However I have a few questions about it.

  Q1. Since the NFS mount will indeed be file system media, this means that for the storage for the Cluster option and the RAC database that I can only use option 'shared file system' and not 'ASM '?

  I think what is confusing me is that I think that I read that the ASM disks can be complete physical disks, partitions of a disk, SAN LUNS or NFS?

  If this is the case then it suggests that I can create an ASM disk based on a NFS mount?

  I don't know how to do this - any help / advice would be appreciated because ideally, I would have preferred to create candidate ASM disks based on the shared NFS disk

  Thank you

  Jim

  You can use NFS as your clustered file system, but if you want to use ASM we top of the page so it no problem: dd to create large files on the file system shared, for example,

  If DD \u003d/dev/zero of = / mnt/nfs/asmdisk1 bs = 1048576 count = 2048

  and set your asm_diskstring parameter to point to them (or specify them as devices to be used at installation time). It is very easy to set up and is fully supported by Oracle of the uncle. I recorded a few demos that include this a year or two before, Oracle ASM free tutorial
