Here is the logs after stopping all three volumes and restarting glusterd in all nodes.

Glusterd proccess hangs on reboot
I have been using a 60 server 1560 brick 3.7.11 cluster without problems for 1 years. I did not see this problem with it. Note that this problem does not happen when I install packages & start glusterd & peer probe and create the volumes. But after glusterd restart. Also note that this still happens without any volumes. So it is not related with brick count I think... On Mon, Sep 4, 2017

No worries Serkan, You can continue to use your 40 node clusters. The backtrace has resolved the function names and it *should* be sufficient to debug the issue. Thanks for letting us know. We'll post on this thread again to notify you about the findings. On Sat, Sep 2, 2017 at 2:42 PM, Serkan ?oban <cobanserkan at gmail.com> wrote: > Hi Milind, > > Anything new about the

Here you can find 10 stack trace samples from glusterd.

Glusterd proccess hangs on reboot
I believe logs you have shared logs which consist of create volume followed by starting the volume. However, you have mentioned that when a node from 80 server cluster gets rebooted, glusterd process hangs. Could you please provide the logs which led glusterd to hang for all the cases along with gusterd process utilization. Thanks Gaurav On Tue, Aug 29, 2017 at 2:44 PM, Serkan ?oban

Multi petabyte gluster
We are using 3.10 and have a 7 PB cluster. We decided against 16+3 as the rebuild time are bottlenecked by matrix operations which scale as the square of the number of data stripes. There are some savings because of larger data chunks but we ended up using 8+3 and heal times are about half compared to 16+3. -Alastair On 30 June 2017 at 02:22, Serkan ?oban <cobanserkan at gmail.com>

Brick count limit in a volume
Hi, Gluster version is 3.10.5. I am trying to create a 5500 brick volume, but getting an error stating that 4444 bricks is the limit. Is this a known limit? Can I change this with an option? Thanks, Serkan
