Strange df -h output

Hi. Last night I received an alert of one of our server indicating that one of our filesystem was full. I then proceeded to log in the system to see what was happening and did a: df -h and here's the output that I got in the filesystems that were full:

Filesystem Size Used Available Capacity Mounted on
root_domain#root 2837M 245M 2585M 9% /
oasis#oasis 8681M 1848M 0 100% /oasis
oasis#u01 8681M 405M 0 100% /u01
oasis#transact 8681M 6460M 0 100% /transact


See how the Size, and Used doesn't correspond to the Available and Capacity columns. I wonder what could be happening here since I nothing is running on this server and I already checked for files newer and bigger and found nothing. If anyone could shed some light on this, I would really appreciate any help.

Thanks!

Re: Strange df -h output

The last three file systems share one AdvFS
domain ("oasis#"). 1848+ 405+ 6460 = 8713,
which is at least 100% of 8681.

It looks full to me.

Yes, even though the last three are different filesystems, they all belong to the same AdvFS domain 'oasis' and draw their storage from the same volume.
