similar to: Brick count limit in a volume

Hi, I think this is the line limiting brick count: https://github.com/gluster/glusterfs/blob/c136024613c697fec87aaff3a070862b92c57977/cli/src/cli-cmd-parser.c#L84 Can gluster-devs increase this limit? Should I open a github issue? On Mon, Aug 21, 2017 at 7:01 PM, Serkan ?oban <cobanserkan at gmail.com> wrote: > Hi, > Gluster version is 3.10.5. I am trying to create a 5500 brick

This is the command line output: Total brick list is larger than a request. Can take (brick_count 4444) Usage: volume create <NEW-VOLNAME> [stripe <COUNT>] [replica <COUNT>] .... I am testing if a big single volume will work for us. Now I am continuing testing with three volumes each 13PB...

An upstream bug would be ideal as github issue is mainly used for enhancements. In the mean time, could you point to the exact failure shown at the command line and the log entry from cli.log?

Here is the logs after stopping all three volumes and restarting glusterd in all nodes. I waited 70 minutes after glusterd restart but it is still consuming %100 CPU. https://www.dropbox.com/s/pzl0f198v03twx3/80servers_after_glusterd_restart.zip?dl=0 On Tue, Aug 29, 2017 at 12:37 PM, Gaurav Yadav <gyadav at redhat.com> wrote: > > I believe logs you have shared logs which consist of

Hi Gaurav, Any progress about the problem?

glusterd returned to normal, here is the logs: https://www.dropbox.com/s/41jx2zn3uizvr53/80servers_glusterd_normal_status.zip?dl=0 On Tue, Aug 29, 2017 at 1:47 PM, Serkan ?oban <cobanserkan at gmail.com> wrote: > Here is the logs after stopping all three volumes and restarting > glusterd in all nodes.

Here you can find 10 stack trace samples from glusterd. I wait 10 seconds between each trace. https://www.dropbox.com/s/9f36goq5xn3p1yt/glusterd_pstack.zip?dl=0 Content of the first stack trace is here: Thread 8 (Thread 0x7f7a8cd4e700 (LWP 43069)): #0 0x0000003aa5c0f00d in nanosleep () from /lib64/libpthread.so.0 #1 0x000000303f837d57 in ?? () from /usr/lib64/libglusterfs.so.0 #2

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

I am working on it and will share my findings as soon as possible.

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

Till now I haven't found anything significant. Can you send me gluster logs along with command-history-logs for these scenarios: Scenario1 : 20 servers Scenario2 : 40 servers Scenario3: 80 Servers Thanks Gaurav On Mon, Aug 28, 2017 at 11:22 AM, Serkan ?oban <cobanserkan at gmail.com> wrote: > Hi Gaurav, > Any progress about the problem? > > On Thursday, August 24,

i usually change event threads to 4. But those logs are from a default installation.

Not yet. Gaurav will be taking a look at it tomorrow.

Serkan, I have gone through other mails in the mail thread as well but responding to this one specifically. Is this a source install or an RPM install ? If this is an RPM install, could you please install the glusterfs-debuginfo RPM and retry to capture the gdb backtrace. If this is a source install, then you'll need to configure the build with --enable-debug and reinstall and retry
