[Gluster-users] 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! I?aki

[Gluster-users] replace brick in distributed-dispersed setup
Hi I?aki 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?
