[Gluster-users] never ending logging

Hi Nicolas,
I would like to mention 2 things here.
1) The bricks not coming online might be because of the glusterd not being
in the right state.
As you mentioned above, the node rejection is most probably because of the
volfile mismatch.
During the glusterd reboot, we check for the volfile in each of the nodes
to be the same.
If any node has a difference in volfile, you will notice that node to be
rejected in the peer status.
To overcome this, we usually delete/copy-paste the volfile from the correct
machine to the rest
and then restart glusterd on each node one after the other. @Sanju Rakonde
<srakonde at redhat.com> can explain more on this.
2) The "another transaction is in progress" is a message you usually get
when you try to
run any gluster command from different nodes. This would rarely hit the
locking part and throw this message.
If you see it a number of times, then it might be the fact that glusterd is
hanging somewhere.
If you saw this post the above rejection issue, please do fix the glusterd
as per the above steps and then try.
That should fix it. Else we need to restart gluster for this particular
issue
Looks like the resultant state is because of the volfile mismatch, please
do check fix that. This will inturn fix the
peer rejection. Once the rejection is fixed, rest of the things should fall
into the right place.
