Hi Iñaki
The steps you are following don't have any issue.
I would like to have more information to debug this further.
1 - gluster v info <volname>
2 - gluster v status <volname> before and after running replace-brick
3 - Brick logs (for this volume only) from /var/log/glusterfs/bricks/4 - glusterd logs /var/log/glusterfs/ starts with "usr-local-etc-glusterfs-glusterd-<volname>"
Although it should not matter, could you also try to replace a brick without killing that brick process?

Subject: replace brick in distributed-dispersed setup
Hi all,
I'm doing some testings with glusterfs in a virtualized environment
running a 3 x (8 + 4) distributed-dispersed volume simulating a 3 node
cluster with 12 drives per node configuration. The system versions are:
OS: Debian jessie kernel 3.16
Gluster: 3.8.0-2 installed from the gluster.org debian repository
I have tested the node failure scenario while some clients are running
some read/write operations and the setup works as expected. Now I'm
trying to test how to replace a faulty drive on this setup, however I'm
not able to replace a brick. To test it I have:
1: Find the pid of the brick I'd like to 'fail' and kill the process.
(tried removing the drive from the host but that would make the whole
guest unresponsive)
2: Attach a new virtual drive, format and mount it
3: Try the gluster volume replace-brick command
And I'm getting the following error:
gluster volume replace-brick vol_1 glusterserver1:/ext/bricks/brick-1
glusterserver1:/ext/bricks/brick-13 commit force
volume replace-brick: failed: Fuse unavailable
Replace-brick failed
I assume I'm doing something wrong but don't know what exactly. Looking
in the documentation I have not found information about brick
replacement in distributed-dispersed setups.
Thanks!
Iñaki
