[Gluster-users] Probable file corruption on a simple setup with Debian Lenny?

[Giovanni Toraldo]

Hi,

I am evaluating GlusterFS for the first time, and I have a problem with
a pretty simple setup:

I have 1 server and 9 clients with Debian Lenny, glusterfs installed
from backports (2.0.9-3~bpo50+1);

GlusterFS is used to export /home directory to clients.

What I see, is that randomly people on clients get their iceweasel
profiles locked out: "Another instance of Icewesel is already running,
try to reboot, etc". Obviously there isn't any sign of running iceweasel
process nor segfaults. I usually recover this situation doing an 'rm
.mozilla/firefox/Profiles/*/.parent' of the user reporting the problem.
Today also happened that an Openoffice istance keep crashing on every
launch, and I resolved it doing a 'rm -fr .openoffice.org'.

I constantly check both server and clients logs, without seeing any
warning nor error.

Any hint? Someone that is using GlusterFS from Debian backports with
success?

Thanks.
