Package Halt Fails

[James Colby]

All -

When I try to halt a mcsg package I get the following error:

exportfs error: /sapmnt/PRD: unable to remove entry from /etc/xtab.
ERROR: Function un_export_fs
ERROR: Failed to unexport /sapmnt/PRD

any ideas on how to clear this up?

Hi James,

Are you exporting this filesystem for NFS use. If so, in your shutdown script you can unexport the filesystem using,

exportfs -u /exported_filesystem_or_directory

Hope this helps.

Just to add, the reason you're getting this error is you probably have added the entry in /etc/exports while ServiceGuard is running.

Yes, I am exporting the file system for NFS use. I believe that my control script is trying to unexport that filesystem during the package halt and that is when the error is being generated. But maybe I'm wrong.

Actually I have already checked my /etc/exports file and that file sytstem is not in it. Thanks for the suggestion.

Hi James,

Since you want to export the filesystem for NFS use, do this, the exportfs (to export filesystem) command should be the last line in your startup script (or customer_defined_run_commands) and the exportfs (to unexport filesystem) should be the first line in your shutdown script (or customer_defined_halt_commands) in your package control script. There is a possibility that once you export the filesystem and try to unexport it, it may be in use, to kill all the proceeses using that filesystem, add a line "fuser -ck /mount_point" to your shutdown scripts before unexporting the filesystem.

Hope this helps.

Thanks everyone for your suggestions. I found the problem, I was trying to unexport the filesystem twice in my control script.
