[Gluster-users] problem adding brick to existing replicated volume
I ran into a problem this morning trying to add a brick to an existing replicated volume containing two servers. I was able to probe the host initially, but then the add-brick failed: --- $ gluster peer probe shake Probe successful $ gluster peer status Number of Peers: 2 Hostname: vh-prod02 Uuid: 3bd398ca-5ae3-4bfd-826b-1412bb5b2407 State: Peer in Cluster (Connected) Hostname: shake Uuid: 71460539-c247-4439-b5cd-c5316b71c5ea State: Peer in Cluster (Connected) $ gluster volume add-brick images replica 3 shake:/srv/glusterd/images Operation failed on shake Looking at the information on the volume: --- $ gluster volume info images Volume Name: images Type: Replicate Volume ID: a3f5f6b2-6076-47a6-b4ae-8ed463766334 Status: Started Number of Bricks: 1 x 3 = 3 Transport-type: tcp Bricks: Brick1: vh-prod01:/srv/glusterd/images Brick2: vh-prod02:/srv/glusterd/images Brick3: shake:/srv/glusterd/images Options Reconfigured: performance.cache-size: 512MB network.ping-timeout: 10 So it shows the brick even though it says operation failed. I've since removed the brick with: --- $ gluster volume remove-brick images replica 2 shake:/srv/glusterd/images Removing brick(s) can result in data loss. Do you want to Continue? (y/n) y Operation failed on shake That also failed, but now shows: --- $ gluster volume info images Volume Name: images Type: Replicate Volume ID: a3f5f6b2-6076-47a6-b4ae-8ed463766334 Status: Started Number of Bricks: 1 x 2 = 2 Transport-type: tcp Bricks: Brick1: vh-prod01:/srv/glusterd/images Brick2: vh-prod02:/srv/glusterd/images Options Reconfigured: performance.cache-size: 512MB network.ping-timeout: 10 Although now this shows up: --- $ gluster volume heal images info Heal operation on volume images has been successful Brick vh-prod01:/srv/glusterd/images Number of entries: 1 / Brick vh-prod02:/srv/glusterd/images Number of entries: 1 / which concerns me a bit. I'm running 3.3.0 on RHEL x86-64. Anyone have any suggestions at this point? -- Mark Nipper nipsy at bitgnome.net (XMPP) +1 979 575 3193 - 'Whenever a politician starts talking about "the children," keep one eye on your wallet and the other on your liberty.' -- anonymous
