[Gluster-users] Pre Validation failed when adding bricks
Hello, When I try to add 3 bricks to a working cluster composed of 3 nodes / 3 bricks in dispersed mode 2+1, it fails like this : root at gl1:~# gluster volume add-brick vol1 gl4:/data/br1 gl5:/data/br1 gl6:/data/br1 volume add-brick: failed: Pre Validation failed on gl4. Host gl5 not connected However all peers are connected and there aren't networking issues : root at gl1:~# gluster peer status Number of Peers: 5 Hostname: gl2 Uuid: 616f100f-a3f4-46e4-b161-ee5db5a60e26 State: Peer in Cluster (Connected) Hostname: gl3 Uuid: acb828b8-f4b3-42ab-a9d2-b3e7b917dc9a State: Peer in Cluster (Connected) Hostname: gl4 Uuid: 813ad056-5e84-4fdb-ac13-38d24c748bc4 State: Peer in Cluster (Connected) Hostname: gl5 Uuid: a7933aeb-b08b-4ebb-a797-b8ecbe5a03c6 State: Peer in Cluster (Connected) Hostname: gl6 Uuid: 63c9a6c1-0adf-4cf5-af7b-b28a60911c99 State: Peer in Cluster (Connected) : When I try a second time, the error is different : root at gl1:~# gluster volume add-brick vol1 gl4:/data/br1 gl5:/data/br1 gl6:/data/br1 volume add-brick: failed: Pre Validation failed on gl5. /data/br1 is already part of a volume Pre Validation failed on gl6. /data/br1 is already part of a volume Pre Validation failed on gl4. /data/br1 is already part of a volume It seems the previous try, even if it has failed, have created the gluster attributes on file system as shown by attr on gl4/5/6 : Attribute "glusterfs.volume-id" has a 16 byte value for /data/br1 I already purge gluster and reformat brick on gl4/5/6 but the issue persist, any ideas ? did I miss something ?

[Gluster-users] Pre Validation failed when adding bricks
1. Could you mention which gluster version are you running with? 2. Does restarting glusterd instance on gl1 & gl5 solves the issue (after removing the volume-id xattr from the bricks) ?
