Cannot write to a NFS data store

• Unable to read / write in the NFS data store

  Hi all
  I'm having a problem with a NFS datastore in Vcenter. I have an NFS share on a Win2k3 server which I am able to mount. However... I can't write him even though the permissions appear to be correct.  This server is connected to an array of training Vault EVA Storage with 2 TB of storage.
  Looks like he's not more as when I try to mount ad content, it shows as 0.00 B ability... and I know that there are files in the NFS data store. Same Host, I can mount my other NFS datastore successfully since a 2008 Server, just do not know which cannot be configured correctly here.

  Help, please... been at this for 2 days banging my head on my desk!

  Screenshots are attached. If there are log files that I could post that would help, please let me know and I'll join them as well.
  Thank you!

  Woot! It worked. I changed the local article, but then authorized security strategy anonymous access with the 2 GID and UID - 2. Once this is done, it is now properly show in Vcenter and allow me to read and write in the data store. Before that I got the value 0.0 even with security policy, change that did not work. So I hope that this issue helps someone in the future, and they do not have a hair pulling experience like I did.

  WHAT A PAIN!

  in any case, thank you all for your time.

• ESX4.1 - cannot connect to a NFS data store

  Hello

  I just installed the ESX4.1 for the test and tried to connect it to a NFS data store but it didn t work.

  After I get all the parameters in the add storage wizard and click Finish it displays the following message:

  -

  ---

  An error occurred during the configuration of the host

  Call 'HostDatastoreSystem.CreateNasDatastore' of object "datastoreSystem-9 'on vCenter Server 'WINSVR-TESTE1' has failed."

  -

  Please note that I have configured this same NFS on an ESX4.0 and it worked fine.

  Does anyone have any suggestions?

  Thank you

  Marcos

  Make sure that the vmkernel port is configured correctly. Is there something in the vmkernel log file?

  Maybe http://kb.vmware.com/kb/1005948 can help (even if 4.1 is not in the list)

• 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. Online: 1 char: 3 + cd & lt; & lt; & lt; & lt; dsBackup: Set-Location: cannot find path ' dsBackup:------' because it does not exist. Line: 1 char: 3 + cd & lt; & lt; & lt; & lt; dsBackup:

  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.

  Have you tried with VITK 1.5?

• 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?

• Is Microsoft Failover Cluster ESXi 4.1 Shared Disk of NFS data store, it supported?

  Is Microsoft Failover Cluster ESXi 4.1 Shared Disk of NFS data store, it supported?

  We have a request from MS Failover Cluster configuration on Windows 2008 R2 2 guests with a storage shared for a web application. However, there is no VMFS storage of data or the ability of the CF to presending RDM. So, I created the disks shared on a NFS datastore using option "Setup for Failover Clustering and Microsoft Cluster Service" and have added the cluster disk and tested successful failover.

  But the MS cluster validation control cancelled storage and I want to know if that configuration is not taken because of supported.

  A notice would be useful.

  We are also working on setting up a cluster of ESXi for iSCSI storage, which can be leveraed for this purpose.

  Shyam-

  Its not supported.

  4.1, your only options supported are:

  • CF storage with pRDMs
  • iSCSI storage with initiators guest.

• HA will only work if I share NFS data store in the cluster

  Hi all

  Please help me with my question below?

  HA work if I share NFS data store in the cluster? Even if if works is it advisable?

  Thank you

  Yes, but a VM restarts on a host within the same cluster VMware only.

• 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.

• 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.

• 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.

  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...

• Prevent write access to a data store

  All,

  I hope someone can advise me on this problem?

  The scenario:

  We have introduced a new LUN in our ESX 4.0 cluster, configured as a data store VMFS and storage vmotion to migrate from a number of virtual machines on this data store. Each virtual machine is turned off. Logic unit number is presented an IBM DS8100 storage array. At a specified time, the LUN is migrated to a remote data center, where we intend to present the LUN to a cluster of replacement and saving virtual machines on this LUN. This provides a method of migration of virtual machines between remote sites.

  The problem is when we test this guy storage advise that there are tracks out of sync in the replicated data, which they claim is due to the LUN writes during replication (which seems unlikely that all the virtual machines on this LUN were stop). According to me, the question is at the end of storage but have been asked to determine if there is a method to isolate completely the LUN of the cluster ESX source to ensure that no data is written during the migration.

  The methods that I have considered are:

  (1) delete the data store - not a viable option that he would destroy all data on the LUN.

  (2) turn off all the paths to the data store by using the vSphere client. It resembled a possibility - I can deactivate 3 of the 4 paths to an ESX host, but get an error when I try to disable the fourth.

  (3) use esxcfg-mpath to disable paths - not convinced that this will work any different use of the GUI.

  (4) get the guys from storage to use to prevent ESX hosts to 'see' the LUN of LUN masking. My problem with this is how ESX will react if she can't see the data store.

  My question is, is anyone know of any method I can use to ensure that this LUN cannot be written in during the migration to the remote site?

  Many thanks in advance,

  Martin

  Yes, ESX will complain, but once you log LUN return - everything will be ok.

  Remove the inventory of VMs (but don't delete disk) before disconnection LUN and ESX will not say anything.

• 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.

• 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?

• How to add a second ESXi02 host to an existing NFS data store used by ESXi01?
