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 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
