[Ocfs2-users] Space not reclaimed after deletion of files.

Hi,

I've got two machines connecting to an ocfs2 filesystem on an iSCSI
target provided by our hosting company (the iSCSI target is on an HP
SAN). After a bit of usage any deleted files disappear, but checking
the usage with "df" shows that space is not being reclaimed.
I've unmounted the partition from both nodes and run "fsck.ocfs2 -fy
/dev/sdb1" which found a whole lot of orphaned inodes which is
apparently fixed.
Remounting showed that the space still was not reclaimed. I did some
testing to see whether the information supplied by "df" was simply
incorrect, but once the partition showed as full I could not write
anything more to it.

After the weekend I tried to remount the full partition and had the
attached kernel errors splash across the screen. I had to power cycle
the server through the hosting company's interface to get it
responsive again. I then had to do a mkfs.ocfs2 to be able to mount
the partition without those kernel errors.

OS: Ubuntu 9.04 (Jaunty)
ocfs2: 1.5.0 (from "modinfo ocfs2")
ocfs2-tools: 1.3.9-0ubuntu3

Is there any more information I can provide that might help with this?

Thanks
Guy
