get-nafile : Unable to stat /vol/PIShare1/piroot7: No such file or directory

[#1]

Current open case: https://smartsolve.netapp.com/case?case_id=2006143948

Normally we refer the customer to the Community forums when it involves Powershell and SDK. Bbut since the case has been open for 2 weeks without progress, I decided to work with the customer to find a solution. 

Summary:

 Is something wrong with the commands I am sending, considering the differences from test to production, since these same commands work in test.

The API/Powershell is a new tool for us and we might be doing something as simple as leaving off a switch or maybe there are syntax differences we would need because of differences in our Test and Prod environments. Test and prod differences as I see it are the following.

In test, the files are directly on the controller, pjaxfas0102 /vol/pi_tm_test/piroot/…..
I make my connection to pjaxfas0102 and I can see anything in the directories and files that are on the controller.

In Prod, the files are on a vfiler (jaxfas5113), attached to the controller (pjaxfas0101) /vol/PIShare1/piroot7/…..
I make my connection to pjaxfas0101 and I can see only the level below /vol like PIShare1.

Quesitons:

1. if WORM is enabled on the file, then will this not work. Will a read-nafile work instead? (i will have the customer try this)

thank you

Hi,

Could you please post the rest of your code\commands? When you connect to your production controller that is hosting the files within the vfiler context did you specify the -Vfiler parameter to the "Connect-NaController" CmdLet? If not then the global nacontroller object will be set to the context of the physical controller (not to the vfiler) and the "Get-NaFile" CmdLet does not accept a -Vfiler parameter so when connecting to your controller in production you would need to set the -Vfiler parameter on the "Connect-NaController" CmdLet. The Syntax is:

Syntax:
 
Connect-NaController [-Name] <String> [-Port <UInt16>] [-Credential <PSCredential>] [-HTTPS] [-HTTP] [-RPC] [-Transient] [-Vfiler <String>] [-Tim
 eout <Int32>] [<CommonParameters>]

Get-NaFile [-Path] <String> [-Controller <NaController>] [<CommonParameters>]

Can you please try the following code:

[String]$controller = "pjaxfas0101"
[String]$vFiler     = "jaxfas5113"
[String]$mountPoint = "/vol/PIShare1/piroot7"
$credentials        = $host.ui.PromptForCredential("Connect to vfiler ""$vFiler"" on controller ""$controller""", "Please enter the user name and password", "", "")
#'------------------------------------------------------------------------------
#'Connect to the vfiler on the controller.
#'------------------------------------------------------------------------------
Import-Module DataONTAP
Try{
   Connect-NaController -Name $controller -HTTPS -Vfiler $vFiler -Credential $credentials -ErrorAction Stop | Out-Null
   Write-Host "Connected to vfiler ""$vFiler"" on controller ""$controller"""
}Catch{
   Write-Warning -Message $("Failed Connecting to vfiler ""$vfiler"" on controller ""$controller"". Error " + $_.Exception.Message)
   Exit -1
}
#'------------------------------------------------------------------------------
#'List the file and directory information in the mount point.
#'------------------------------------------------------------------------------
Try{
   Get-NaFile -Path $mountPoint -ErrorAction Stop
}Catch{
   Write-Warning -Message $("Failed listing files in ""$mountPoint"" on vfiler ""$vfiler"" controller ""$controller"". Error " + $_.Exception.Message)
   Exit -1
}
#'------------------------------------------------------------------------------

Please post any error messages and let me know if you have any questions. Hope this helps

I added the -vFiler parameter, and also added the -https parameter

I got the following return from the script 

WARNING: Failed Connecting to vfiler "jaxfas5113.corp.citistreet.org" on controller "pjaxfas0101.dsglobal.org". Error Unknown vfiler name in API request.

When I just run the connect string by itself, i get the following error

Connect-NaController : Unknown vfiler name in API request

I was able to get past the Vfiler not found by removing the FQN from the script, I am still however getting the File Not Found Error.

Hi,

Try using the "Read-NaDirectory" CmdLet to list the files and directories within the volume. You then need to check the objects type to determine if it is a file or a directory and if it is a file you can then use the "Get-NaFile" CmdLet to list the file. EG:

[String]$controllerName = "testns01.testlab.local"
[String]$vfilerName     = "testnv01"
[String]$volumeName     = "volume_01"
$credentials            = Get-Credential
#'------------------------------------------------------------------------------
#'Connect to the vfiler on the controller.
#'------------------------------------------------------------------------------
Try{
   Connect-NaController -Name $controllerName -Vfiler $vfilerName -HTTPS -Credential $credentials -ErrorAction Stop | Out-Null
   Write-Host "Connected to vfiler ""$vfilerName"" on controller ""$controllerName"""
}Catch{
   Write-Warning -Message $("Failed connecting to vfiler ""$vFilerName"" on controller ""$controllerName"". Error " + $_.Exception.Message)
   Exit -1
}
#'------------------------------------------------------------------------------
#'List the files and directories in the volume.
#'------------------------------------------------------------------------------
Try{
   $results = read-nadirectory "/vol/$volumeName"
   Write-Host "Enumerated files and directories in ""/vol/$volumeName"""
}Catch{
   Write-Warning -Message $("Failed listing files and directories in ""/vol/$volumeName"". Error " + $_.Exception.Message)
   Exit -1
}
#'------------------------------------------------------------------------------
#'list any files in the volume.
#'------------------------------------------------------------------------------
ForEach($result In $results){
   If($result.Type -eq "file"){
      [String]$filePath = $("/vol/$volumeName/" + $result.Name)
      Try{
         $file = Get-NaFile "$filePath" -ErrorAction Stop
         $file | Format-List
      }Catch{
         Write-Warning -Message $("Failed listing file ""$filePath"". Error " + $_.Exception.Message)
      }
   }
}
#'------------------------------------------------------------------------------

Thank you for reviewing this issue. 

I tried the Read-NaDirectory, using your modified script and I still am not finding the files and folders under the volume level.

I then reran the Read-NaDirectory lines specifically.  And noticed something in result from the volume level  read

read-nadirectory /vol/PIShare1

read-nadirectory /vol/PIShare1

Name                                     Type            Size      Created     Modified Owner Group   Perm Empty

..                                       directory      12 KB    5/13/2010    3/11/2016     0     0    777 False
.bplusvtoc_internal                      directory       4 KB     6/8/2014     6/8/2014     0     0      0 True
.vtoc_internal                           directory       4 KB     6/8/2014     6/8/2014     0     0      0 True
PIShare1                                 directory      20 KB    5/13/2010     3/3/2016     0     0    777 False

It seems as if the command doesn't see any of the contents of the PIShare1 folder, there are at least 6 different directories directly in the PIShare1 Volume as you can see from the command belows result.

read-nadirectory /vol/PIShare1/piroot7

To give some further background:

Ultimately what I am trying to accomplish using the PS scripts and API code is to reset file retention dates further into the future since files that were previously snaplocked and set to a WORM state now are exceeding the initial default retention period and the files need to be retained longer in an unmodifiable state.  To accomplish this I coded a Vb.net application using a combination of standard .Net file system calls to recursively scan all directories and files to determine if the Date Modified file attribute was set into the future.  Using the .net file system calls I build a list of files which need to have there retention date reset.  I then run the list through a Netapp API call to 'file-set-snaplock-retention-time' with the file path and new retention date.  This code worked fine in our test environment.  Once I moved to our production environment I was getting file not found on all path/file combinations that I was passing to the file-set-snaplock-retention-time API Call.  In order to try to determine the issue I started investigating other commands that I could test with that didn't do anything destructive sense the data in production is live data.  My theory being that If I can't find the file with a simple read like Get-NAFile, then I surely wouldn't be able to run something like a set-NasnaplockRetentionTime or the VB.Net call of file-set-snaplock-retention-time.  Hope this helps

Thanks again in advance

Hi,

Just to close out this thread the solution was to ensure the CIFS Share's mount point is valid. EG

$controllerName = "pjaxfas0101.dsglobal.org"
$vfilerName     = "jaxfas5113"
$shareName      = "PIShare1"
$credentials    = Get-Credential
Import-Module DataONTAP
Connect-NaController -Name $controllerName -Vfiler $vfilerName -HTTPS -Credential $credentials
$share = Get-NaCifsShare -Share $shareName
Write-Host $("listing directories and files within CIFS share ""$shareName"" in mount point """ + $share.MountPoint + """ on vFiler ""$vfilerName""")
$share | Format-List
Read-NaDirectory -Path $share.MountPoint
