Gluster users - Feb 2012 - Hanging writes after upgrading "clients" to debian squeeze

Hi,

I am running a simple gluster storage server setup with 2 nodes, one volume with
two bricks and replication. My "clients" are webservers which mount
the gluster storage via native client. My storage server run debian squeeze for
some while now and today I upgraded my webservers from debian lenny to debian
squeeze. The gluster version I am running is 3.2.0, self compiled. After the
debian upgrade I can still mount my volumes. Reading is fine as well but it
hangs on writes. I did not touch the storage servers at all. I did not upgrade
all webservers so I still have some running with debian lenny and everything
works just fine. The log files are rather empty, at least I cannot find anything
during the hanging write.

Do you guys have any idea how to fix this?

Regards,
Stefan

I would start by updating to 3.2.5 and see if you still have the same issue.

Could it be that on the post-upgrade machines one brick is reachable but not
the other?  Compare iptables rules between the pre-upgrade and post-upgrade
machines?  Compare tcpdump or ntop between them?
