Feb 4 10:54:01 alb-ndm kernel: VFS: Busy inodes after unmount.
Self-destruct in 5 seconds. Have a nice day...
Feb 4 10:56:32 alb-ndm kernel: XFS: Filesystem sd(8,5) has duplicate UUID
- can't mount
The unmount failed beause xfs thought something was still busy, but the
kernel did not. Looks like a reference count leak somewhere in the old
kernel.
That's what I figured. I'll definitely move this to the top of "reasons
to upgrade already!" pile. (I'd do it tomorrow if there were
some XFS-patched RHEL kernels ready to go... ;)
If you reboot and run repair you should be ok.
I found some mention of this on the mailing list where it was suggested to
`mount -o nouuid`. This worked for me - the filesystem recovered itself,
and I see the freed space now.
Those unlinked bucket messages refer to unlinked inodes which should
have been freed at some point. They probably still have a reference
count inside xfs which means they did not get freed. This is where
your space has gone.
Well, now I know more about XFS internals than I did before. Always has
to learned the hard way...
Thanks for your replies.
