[Gluster-users] 3.1.2 feedback

Sat Jan 22 03:34:22 UTC 2011

I have been testing 3.1.2 over the last few days. My overall
impression is that it resolved several bugs from 3.1.1, but the latest
version is still prone to crashing under moderate to heavy loads.

I was running some stress tests on a two server replicated setup today
with ~150 clients connected with RDMA. The glusterfsd process crashed
on one server. I waited about 30 minutes to see if the automatic
fail-over would work, but I continued to receive "Transport: endpoint
not connected" error messages on all the clients. I saw the following
error messages in the server log:
(I removed several hundred error messages from the following snippet)

I think the crash is related to this bug:
http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=2197

I ran some smaller tests on a single server setup. The were ~50
clients connected via RDMA. While the jobs were running, several of
them crashed with "File descriptor in bad state" or "Stale File
Descriptor" errors. Here are the error messages from the server log:

(I removed dozens of similar error message)

The glusterfsd process did not crash in that instance.
