Re: Adding a new replica to the cluster

[Atin Mukherjee <amukherj@xxxxxxxxxx>]

Apologies for the delay!

From the logs:

[2017-05-31 13:06:35.839780] E [MSGID: 106005] [glusterd-utils.c:4877:glusterd_brick_start] 0-management: Unable to  start brick 156.125.102.103:/data/br0/vm0                                                                           
[2017-05-31 13:06:35.839869] E [MSGID: 106074] [glusterd-brick-ops.c:2493:glusterd_op_add_brick] 0-glusterd: Unable  to add bricks

This looks like in serv3 the newly added brick failed to come up. You'd have to look at the same brick log file on serv3 to see what was the reason. As a workaround, does gluster v start <volname> force bring up this brick now? As far as glusterd configuration data is concerned, everything seems fine, no inconsistency.

Hello,

Here is a tar gz with the log, and the output of "gluster volume status && gluster volume info && gluster peer status" for each server

Thank you,

Merwan

Gluster peer status tells me that the peer is connected

Here is the log from the servers in the cluster (they are the same for both of them):

https://pastebin.com/4aM94PJ6

The log from the server i'm trying to add to the cluster:

https://pastebin.com/YGTcKRyw

I'm sorry but these log files are for brick and client. What I am looking for is glusterd log ( ls -lrt /var/log/glusterfs/*glusterd* ) from all the nodes. Also please paste the output of gluster volume status, gluster volume info, gluster peer status from all the nodes.

Hello,

I wanted to play around with gluster and I made a 2 nodes cluster replicated, then I wanted to add a third replica "on the fly".

I manage to probe my third server from the cluster, but when I try to add the new brick to the volume, I get a "Request timed out"

My command:
  gluster volume add-brick vol0 replica 3 192.168.0.4:/data/br0/vol0

This might happen if the originator glusterd lost connection with other peers while this command was in process. Can you check if peer status is healthy by gluster peer status command? If yes, you'd need to share the glusterd log files from all the nodes with us to further analyse the issue.

 

Does anyone have an idea ?

Merwan
