[ovirt-users] Storage Domain used space strangeness

[urthmover]

Oddly a reboot of the host resulted in the space showing up correctly.

[root at jmini08 ~]# df -h /data
Filesystem      Size  Used Avail Use% Mounted on
data-pool       914G  3.5M  914G   1% /data

[root at jmini08 ~]# du -hs /data
3.3M	/data

Snapshots?
# zfs list -t snapshot

What does the hosts that are mouting think? If you log into one of them and run:
# df -h

/K

When I ssh into the host there is 2.2M on the top level of that mount according to du.  How do I account for and reclaim the mysterious space usage?
