[gpfsug-discuss] Can't delete filesystem

[Simon Thompson (Research Computing - IT Services)]

Do you have ILM (dsmrecalld and friends) running?

They can also stop the filesystem being released (e.g. mmshutdown fails if they are up).

Subject: [gpfsug-discuss] Can't delete filesystem

Hi All,

First off, I can open a PMR on this if I need to…

I am trying to delete a GPFS filesystem but mmdelfs is telling me that the filesystem is still mounted on 14 nodes and therefore can’t be deleted.  10 of those nodes are my 10 GPFS servers and they have an “internal mount” still mounted.  IIRC, it’s the other 4 (client) nodes I need to concentrate on … i.e. once those other 4 clients no longer have it mounted the internal mounts will resolve themselves.  Correct me if I’m wrong on that, please.

So, I have gone to all of the 4 clients and none of them say they have it mounted according to either “df” or “mount”.  I’ve gone ahead and run both “mmunmount” and “umount -l” on the filesystem anyway, but the mmdelfs still fails saying that they have it mounted.

What do I need to do to resolve this issue on those 4 clients?  Thanks…

Kevin
