Didn't we we fix this problem recently? Failed to set extended attribute indicates that temp mount is failing and we don't have quorum number of bricks up.
We had two fixes which handles two kind of add-brick scenarios.
[1] Fails add-brick when increasing the replica count if any of the brick is down to avoid data loss. This can be overridden by using the force option.
[2] Allow add-brick to set the extended attributes by the temp mount if the volume is already mounted (has clients).
They are in version 3.12.2 so, patch [1] is present there. But since they are using the force option it should not have any problem even if they have any brick down. The error message they are getting is also different, so it is not because of any brick being down I guess.
Patch [2] is not present in 3.12.2 and it is not the conversion from plain distribute to replicate volume. So the scenario is different here.
It seems like they are hitting some other issue.
@Boris,
Can you attach the add-brick's temp mount log. The file name should look something like "dockervols-add-brick-mount.log". Can you also provide all the brick logs of that volume during that time.
Regards,
Karthik
Boris - What's the gluster version are you using?

I’ve got a replicated volume with three bricks (“1x3=3”), the idea is to have a common set of files that are locally available on all the machines (Scientific Linux 7, which is essentially CentOS 7) in a cluster.
I tried to add on a fourth machine, so used a command like this:
sudo gluster volume add-brick dockervols replica 4 webserver8:/data/gluster/dockervols force
but the result is:
volume add-brick: failed: Commit failed on webserver1. Please check log file for details.
Commit failed on webserver8. Please check log file for details.
Commit failed on webserver11. Please check log file for details.
Tried: removing the new brick (this also fails) and trying again.
Tried: checking the logs. The log files are not enlightening to me – I don’t know what’s normal and what’s not.
From webserver8 & webserver11 could you attach glusterd log files?
Also please share following:
- gluster version? (gluster —version)
- Output of ‘gluster peer status’
- Output of ‘gluster v info’ from all 4 nodes.
Tried: deleting the brick directory from previous attempt, so that it’s not in the way.
Tried: restarting gluster services
Tried: rebooting
Tried: setting up a new volume, replicated to all four machines. This works, so I’m assuming it’s not a networking issue. But still fails with this existing volume that has the critical data in it.
Running out of ideas. Any suggestions? Thank you!
