This is the output of df -h:

mos-storage02:/nova/instances   39G  4.0G   33G  11% /var/lib/nova/instances

That does not seem to be right. It gives me a free disk space of 33G.

Executing df -a -h on mos-storage02gives me:

/dev/mapper/system-root   39G  4.0G   33G  11% /export/nova/instances

It seems to me that I have not mounted the right LVM volume to /var/lib/nova/instances, but exported the folder on the system disk. I will check this.

It seems to me that Oh, no! I think, I have not mounted the right LVM volume to /var/lib/nova/instances, '/dev/storage/nfsto/var/lib/nova/instances`, but exported the folder on the system disk. I will check this.
