• VM shows this in the NFS data store after passed to the vmfs data store

  Hello

  (1) create a virtual machine using NFS datastore

  (2) had created a few snapshots

  (3) to migrate this virtual machine from the data to the local VMfs store

  (4) all the files are moved to the defined vmfs datastore

  (5) storage > > nfs_datastore > > objects > > VM > > vm is present

  (6) but when did change the setting of this VM, vm is present on the data store local vmfs

  The .vmsn file contains binary data text, so you better not change it manually. The purpose of these files is to be able to return to his instant partner. Depending on the configuration of virtual machines in time you created the snapshot, the virtual machine may require access to the old data store to access the files and folders in there when you return to this snapshot.

• Cannot write to a NFS data store

  Hello

  I built a test environment to test ESXi 5.5 u1 to work. I am able to mount the database, browse the data store, but cannot write to it. I mounted on a different host of production and can't read/write very well.

  This happens on both servers in this test configuration. I must add, they used to be the ESX 3.5 hosts and had no problem with NFS data warehouses. I used the same NIC cards to create similar vSwitches. Trunking VLAN on our physical switches has not changed.  The two test servers have access to reading/writing/root for NFS mounting in our SAN (same as before IPs and it worked).

  Any suggestion would be appreciated.

  Thank you

  Well I guess you've got most of the standard things cleared here.

  I fall on this blog:

  http://emcsan.WordPress.com/2011/09/01/VMware-cant-write-to-a-Celerra-RW-NFS-mounted-datastore/

  Which seems to point to a few additional authorization with the EMC Clariion problems that must be addressed to make NFS work in later versions.  This gives a whril on your new hosts and let us know.

• Windows 2008 Server NFS - permission denied when accessing the NFS data store

  Hello

  I'm trying to configure a Windows 2008 Server to store virtual machines on an NFS share.

  When I add the data store to my host, I have no Brown Read-only and the data store is added successfully.

  When I browse the data store, as soon as I try to delete a file or create a folder, I have an error message: "cannot delete" or "cannot complete the file was created.

  It seems to be a problem of rights NFS, but impossible to find what the problem is.

  In the/var/log/vmkernel, I see:

  Mar 23 17:43:07 vmw-esx1 vmkernel: 1:02:37:20.635 cpu4:4109) NFSLock: 2677: can't get the lock on the file new document texte.txt 0x4100070384d0 on circe (10.254.0.19): Permission denied

  Don't you have a howto use NFS with Windows 2008 to help me?  I found one for Windows 2003, but think are too different.

  Or another idea?

  See document attached with the NFS share parameters.

  You must configure the user name mapping in Services for UNIX/NFS and map the root user.  Detailed instructions here: http://www.sohoadvisers.com/tutorials/vmware-esxi/connect-esxi-to-windows-nfs.  I was able to implement some hosts to use my Windows NFS export, but it was a bit unreliable.  This is a configuration not supported with VMware...

• Unable to scp - r of the local data store a host to another data store local host

  Using PuTTY to connect to the host server

  Running command to copy VM to a data store to another data store (the two DS hosted locally on 2 different servers)

  Error: are different major versions of Protocol: 2 vs 1

  -J' tried confirmed that the only protocol on two host servers are defined in Protocol No. 1 and as I use Putty I have the Protocol in 1 also, but the same error occurs.

  II

  1 - Check the SSH configuration on both sides and compare... (/ etc/ssh/sshd_config)

  The remote server will only accept v2 connections and you try to do

  a connection v1. So either enable support of the v1 on the remote side. Or use

  keys v2 and id_rsa/id_dsa.

  2. check the versions ESX & patch level you used on both sides (ESX 3 xx build xxx)

  3 - also, you can check ssh version of protocol running rpm - qa | grep openssh.

  Good luck!

• Getting name of VMhost who questioned when retrieving information about the NFS data stores

  Sorry if the question has already been asked,

  I try to present NFS shares in each ESXi host and that does the trick

  Get-datastore. where type - eq 'NFS ' | Select name

  However, I want to retrieve the name of the host from which the information is retrieved.

  Unfortunately I do not see the name of the $vmhost among the names when I use get-datastore. get-member.

  How I do that?

  Thank you

  Alex

  Try something like this

  foreach($esx in Get-VMHost){    Get-Datastore -RelatedObject $esx |     Where type -eq "NFS" |     Select Name,        @{N="VMHost";E={$esx.Name}},        @{N="Host";E={$_.Extensiondata.Info.Nas.RemoteHost}},         @{N="Mount point";E {$_.Extensiondata.Info.Nas.RemotePath}}}
  

  A way to see what are the properties on an object is like this

  $ds = Get-Datastore -Name DS1$ds.ExtensionData | Format-Custom -Depth 3
  

• ESXi connection to the Windows SFU NFS data store

  We plan to install 3 servers ESXi with virtual machines hosted on local.  A backup script align the images and move the *.vmx and *.vmdk to a NFS data store located in separate facilities which are connected via fiber.  All connections are links of 1 G.  The NFS data store will be hosted on w2k3 with SFU (Microsoft Services for Unix).

  The NFS data store will be a target for cloning and will be located in a building separated for "geographical separation."  I tested with Veema FastSCP (the public beta)... it's ok (30Mbytes/sec).  I assume that the clone process will take about 5 hours - but we can tolerate the performance hit after opening hours.

  Question:  Is there a "traps" to know by linking each ESXi server in the same directory NFS exported using SFU?  Perhaps more to the point... no problem with ESXi and Windows SFU?

  Before anyone asks... we do this on a 'super-thin budget' (that is to say... $ 0) using existing hardware, otherwise I would have ESX Enterprise and SAN storage!

  Some discussions to look at on the performance.

  1.), you don't need to call your "writeback" as your informed XML file. The reference in point answers to and not writeback.xml

  2.) did you put the file in the correct location? That is \OracleBI\web\msgdb\customMessages?

  3.) did you restart your services or at least hit "Reload the files and metadata" in the administration of server close?

  4.) are you sure that you want to do is INSERT and not an update?

  I tested your file here, and it fires off like that.

• Impossible to mount any NFS data store: unable to resolve host name '< obsolete Server > '.

  Hello

  On a particular ESXi server, whenever I try to mount any NFS data store, I get this error message:

  Call "HostDatastoreSystem.CreateNasDatastore" of object "ha-datastoresystem" on ESXi '172.22.216.64' failed.
  Operation failed, the diagnostic report: unable to resolve host name 'cosmo '.

  Always mention hostname 'cosmo', no matter what server I'm actually trying to mount. 172.22.216.64 is the exact address of the ESXi server.

  'cosmo' was the former name of a desktop linux machine, several months ago has re-installed and renamed in the process. So 'cosmo' is no more and it's just expected that 'cosmo' cannot be resolved. However, the error message mentioning 'cosmo' occurs regardless of what server I try to mount a NFS datastore of. I can't find any references to 'cosmo' in the ESXi server configuration in the vSphere client (although I don't know exactly where to look). I remember that at one point, a NFS datastore was mounted temporarily to 'cosmo' to host the ISO debug files. But no more.

  I tried this same sharing of an another ESXi (running the same version of ESXi) mounted in the same subnet (works great), and I also tried to mount a new NFS share on a server where the ESXi already had another NFS data store mounted from the same server (the data store already mounted works fine (, but attempts to connect to a new data store on the same failed server mentioning the independent 'cosmo' server as mentioned above). I tried to restart the ESXi server, but the problem persists after restarting.

  I'm under vSphere client 5.0.0 Build 455964 and ESXi 5.0.0 - 469512-standard with the free license. Because of the free license (I think), I don't have SSH access on the server. (Is that right?)

  How to work around the error message mentioning the obsolete server 'cosmo '? The only thing I can think of right now is to move all data from the local data store to a store of data already mounted, reinstall the ESXi server and give all the data. I'm hoping for a simpler solution! :-)

  Can you confirm if this solution works for you?

• ESXi 5.0 servers don't recognize that same NFS share to the same data store

  I have a setup of vSphere 5.0 running VMware Workstation 8.  I have two ESXi servers that are accumulating the same NFS share (with the same IP address and the same directory path), but for some reason, they don't recognize it as the same data store.  I deleted and added to the data store again and checked that I am getting the same way on both nodes.  However, vSphere don't let me use the same name when I ride sharing NFS as a data store on the second node. vSphere changes the name of "NFSdatastore" to "NFSdatastore (1)" and will not let me change, say that the name already exists.

  The NFS file server is a VM of 2.99 OpenFiler, which IP 192.168.0.100 (and is in DNS as "openfiler1").  The path is "/ mnt/vsphere/vcs/datastore.

  The NFS mount works great as a data store on the two servers ESXi, except for the fact that vSphere sees two data stores.  I have a Red Hat VM running on each of them, and when I browse the data of each ESXi Server store, I can definitely see two configs VM, as well as a few ISO images that I put on the NFS share.  However, I can't vMotion as he complains about not being able to access the configuration file and the file virtual disk (vmdk) of the other node.

  On the OpenFiler, the directory/mnt/vsphere/vcs/datastore is the property of "ofguest" in the "ofguest" group, and the permissions are "drwxrwsrwx +".  All files under the directory are also held by "ofguest" in the group "ofguest".  Vmx files have permissions "rwxr-xr-x + ', and the vmdk files have permissions ' rw +-

  I did a lot of Google search, read best practices, etc.  Any help is appreciated.

  UPDATE: he Figured out - leakage / on one of the paths of NFS mounting.  DOH!

• Unable to browse the server data store

  Hello

  I lost the files in my data store. I have two data warehouses and two of them had vm folders in there but tonight my vms unresponsive and when I try to restart they throw an error that a file is not present. When I tried to browse the data store, the two data stores back empty.

  Hey m,

  can you go on the albums esx server into your virtualcenter

  Try remapping to one of the existing NFS shares. You should get a message that the share already exists, but when you return to the summary page, you should be able to doubleclick on the NFS share and view folders (it's like trying to connect is enough to restore the existing connection)

• Troubleshooting a NFS data store

  A vSphere 5.5 uses a database hosted by a NAS server and store accessible via NFS.

  It has always worked well.

  Now I see that some folders and files on the data store is not accessible, with messages like:

  Move the virtual machine

  < vm_name >

  Was able to complete the network file copy / /vmfs/volumes/e4e525a8-acdae200 / < vm_name > / < vm_name > hard

  Copy of the files of virtual machines

  or:

  Copy the file

  Data store < datastore_name >

  Unable to access file [Datastore < datastore_name >] < folder_name > / < Filename > .iso

  I rebooted the NAS, the hosting data store and forced a file check, but I don't see any change.

  Other files on the NAS even are accessible via CIFS and can be read and written without any problems.

  How to detect my NFS datastore issues and, if possible, to solve?

  Can what tools I use to check and recover the NFS datastore?

  Hello

  is it possible that something has changed in the NFS export? What solution do you use for storage? You can browse the files/folders you want to access from the storage itself?

• Add several NFS data stores to multiple ESX hosts

  I am trying to write a script that will set up several NFS exports to multiple ESX hosts. Here is the script I use, it will add an NFS export to an esx host list.

  $esx = (get-Content servers.txt)

  {}
  $Host_Name = (Read-Host "enter the server (ex: storage-san)")
  $Path = (Read-Host "enter the path (ex: / ds_name/flight/flight)")
  $Name = (Read-Host "Enter the name of the data store")

  {foreach ($server in $esx)
  $Error.Clear)
  Get-VMHost $server | New-Nfs Datastore - NfsHost $Host_Name-path $Path - name $Name | Out-Null
  If ($error.count - gt 0) {$error | out-file ($server, 'c:\powershell scripts\logs\' + '.txt')}
  }

  $add_more = Read-Host "want to show you another data store?
  }
  While ($add_more - eq 'Yes' - or $add_more - eq "y")

  This script actually works OK but I can't just she kick sending and walk. If I have 10 stores of data to add, I have to wait for the current to the end, and then type the information for the second, etc..

  I was hoping just to type all the information from the beginning and the shot of the script to the wide and let him go. Here is what I added, you can see where I'm going with this?

  $esx = (get-Content servers.txt)

  $num_mounts = (Read-Host "Do you have multiple media")
  If ($num_mounts - eq 'Yes' - or $num_mounts - eq "y")
  {
  $mounts = @(Read-Host "supports différents combien avez_vous")

  #prompt me for all the different right monte upwards before and then executed by the actual task of Mount...
  }

  Any ideas?

  Try something like this

  $servers = @()
  $paths = @()
  $datastores = @()
  
  $answer = Read-Host "Enter another NFS mount ?" while($mount -eq "y"){
      $servers += Read-Host "Enter the NFS host"    $paths += Read-Host "Enter the path"    $datastores += Read-Host "Datastore name ?"    $answer = Read-Host "Enter another NFS mount ?"}
  
  $Error.Clear()
  
  Get-Content servers.txt | %{
      $esx = Get-VMHost -Name $_    $countNFS = $servers.Count
      if($countNFS -ne 0){
          0..($countNFS - 1) | %{
              New-Datastore -Nfs -NfsHost $servers[$_] -Path $paths[$_] -Name $datastores[$_] | Out-Null            if($Error.count -gt 0){
                  $Error | out-file ('c:\powershell scripts\logs\' + $server + '.txt')
                  $Error.Clear()
              }
          }
      }
  }
  

  The script reads all the data in the tables.

  Then it loops through all ESX hosts from the servers.txt file, and for each host, it will create all the NFS data storages.

• Mapping in NFS data store fails in PowerShell

  I'm trying to access a data store NFS on my server ESXi of Powershell. I am able to access the VMFS data stores, but not my NFS datastore. I use this command:

  new-psdrive-location (get-data store Backup) - name dsBackup - psprovider VimDatastore-root ' '

  When I type cd dsBackup: I get this error:

  Get-Location: no player named ' \Datastore\ [email protected] \Datastore-172.XXX.XXX.XXX:\VM\' was found for the specified provider.

  I use the same command when you access warehouses of VMFS data without problems. I am able to browse, read and write in the VI Client NFS data store.

  Everyone knows this behavior? Any help would be much appreciated.

  Just tried with an ESXi 3.5 build 130755 store data as well.

  Works well.

  Note that I used VITK 1.5 build 142961 for this last test.
