[Gluster-users] Volume add-brick: failed: (with no error message)

Tue Apr 15 15:26:47 UTC 2014

Hi folks,

We've had a 2 node gluster array working great for the last year. Each
brick is a 37TB xfs mount. It's now on Centos 6.5 (x64) running gluster
3.4.3-2

Volume Name: gfs
Type: Distribute
Volume ID: ddbb46bb-821e-44db-bc7e-32f43334f62c
Status: Started
Number of Bricks: 2
Transport-type: tcp
Bricks:
Brick1: server1:/mnt/data
Brick2: server2:/mnt/data

We've just bought a new server (identical in every way to the previous
two) and we're trying to get it added to the volume.

The peering process goes fine:

Number of Peers: 2

Hostname: server2
Uuid: 02f1a25b-afd8-49e2-8708-95456f6b8473
State: Peer in Cluster (Connected)

Hostname: server3
Port: 24007
Uuid: 3fc9df26-bb49-4c74-8eae-4b3f37389224
State: Peer in Cluster (Connected)

The only thing of interest (?) there is the addition of the port number
for the new server. Neither of the old servers show a port, even when
running the peer status command on any of the boxes.

The main problem is the addition of the new server/brick:

[root at server1 glusterfs]# gluster volume add-brick gfs server3:/mnt/data
volume add-brick: failed:

There's no error there at all: just a blank after the colon.

The logs on server1 (the one trying to do the add):

W [rpc-transport.c:175:rpc_transport_load] 0-rpc-transport: missing
'option transport-type'. defaulting to "socket"
I [socket.c:3480:socket_init] 0-glusterfs: SSL support is NOT enabled

I [cli-rpc-ops.c:1695:gf_cli_add_brick_cbk] 0-cli: Received resp to add brick
I [input.c:36:cli_batch] 0-: Exiting with: -1

And the logs on server3 (the one being added):

E [glusterd-op-sm.c:3719:glusterd_op_ac_stage_op] 0-management: Stage
failed on operation 'Volume Add brick', Status : -1

The current storage array is live and in-use by users, so it can't be
taken offline at short notice.

For completeness, here's glusterd on server3 running in debug mode when
the add-brick command was attempted:
