[Gluster-users] GlusterFS Lockup

[Mark Harrigan]

Hi,

We've been using GlusterFS 3.4.0 on Debian 7 for around 11 months. Every so
often (once every 6 weeks or so) a server running the client and nginx
accessing the gluster storage would suffer a hard lockup of nginx and
require a reboot. This wasn't such a big deal as there were several clients
so there was never a loss to production.

However in the last few days we've seen a huge increase in these lockups.
Perhaps 2-3 times a day on multiple machines.

The bug appears to be very similar to
https://bugzilla.redhat.com/show_bug.cgi?id=764743 from Gluster 3.2 and the
suggestion of first killing the Gluster process does allow a restart of
nginx without a reboot.

The only changes to our usage of late have been to stop a rebalance process
(as we're at the point where we need to add extra bricks) and to breach 80%
usage on the volume (Total volume size is 400TB).

Has anyone else had any experience of this bug re-emerging in Gluster 3.4?

Thanks,

Mark
