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

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.

You still have a dangling dead mount inside the kernel, a reboot at an opportune moment will clean that up.
