[gpfsug-discuss] Can't delete filesystem

[Buterbaugh, Kevin L]

Hi Simon,

No, I do not.

Let me also add that this is a filesystem that I migrated users off of and to another GPFS filesystem.  I moved the last users this morning and then ran an “mmunmount” across the whole cluster via mmdsh.  Therefore, if the simple solution is to use the “-p” option to mmdelfs I’m fine with that.  I’m just not sure what the right course of action is at this point.

Thanks again…

Kevin

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.
