"Create export" command problem

[vladimirzhigulin]

My WF is 1. create a Vol; 2. Export the Vol.

The WF fails with the following:

Missing an argument for parameter 'Anon'. Specify a parameter of type 'System.String' and try again.

I look at log (i changed IP's, names etc.):

10:10:24.625 INFO  [Create Export] Executing command: ./Create_Export2162464948268547412.ps1 -Anon -Array filer16 -NoSuid $true -Path /export -RWhosts @('','root=<IPs here>') -VolumeName volname

..

10:10:49.363 INFO  [Create Export] Expression to invoke: Add-NaNfsExport -Persistent -Path /export -ActualPath /vol/volname -NoSuid -Anon -Root @() -ReadOnly @() -ReadWrite @('','root=IPs here)

10:10:49.545 ERROR  [Create Export] Missing an argument for parameter 'Anon'. Specify a parameter of type 'System.String' and try again.

10:10:49.979 ERROR  [Create Export] Missing an argument for parameter 'Anon'. Specify a parameter of type 'System.String' and try again.

10:10:49.993 INFO  [] ***** Workflow Execution Failed *****

So -Anon doesn't have any value, however it has '0' value in appropriate Define FindChart.

Now I look at "Create Export" command:

..

if ($Anon)

{

    $expression += " -Anon"

}

..

So it seems to me that it should be:

if ($Anon)

{

    $expression += " -Anon $Anon"

}

Or am I missing something here?

Hi Vladmir,

Good catch!

This issue is a known issue and has been fixed in subsequent builds.

The relevant logs :

The corresponding fix in the "Create Export" command(as you correctly pointed out) :

if ($Anon)

{

   $expression += " -Anon " + $Anon

}

Hi Tanzim,

Indeed your fix works as expected.

There is another issue however 😃

My execution logs (no changes to output whatsoever this time):

Now I check /etc/exports on the filer 10.196.68.207:

/vol/csmail     -sec=sys,rw,root=10.146.68.45,nosuid

I don't know what's wrong this time, Add-NaNfsExport  bug?

Hi Vladimir,

The follow up issue that you mentioned was quite tricky to debug. I've managed to find the issue and solution.

I found that when i provided values to the input parameters "RootHosts" and "RWhosts" as 

          RootHosts:     "root1"

          RWhosts:      "rw1 rw2"

the workflow failed to set anon=0 in the /etc/exports file on ONTAP.                                                           

However, when i provided the values as

      RootHosts:     root1

      RWhosts:       rw1,rw2

the workflow successfully set anon=0 in the /etc/exports file on ONTAP.

Please try this out in your setup and let me know if it worked for you.

Hi Tanzin,

Thanks a lot for your help. I can confirm that passing values for both RootHosts and RWhosts as separated by comma in WF works as expected.

Vladimir

[fenton]

Are you wishing to pass something in the anon definition - if no then this field should be left blank in the define chart for the export

Example below...

[vladimirzhigulin]

I really needed to have "-Anon 0".
