[Gluster-users] GlusterFS cluster peer stuck in state: Sent and Received peer request (Connected)

Tue Mar 15 16:27:55 UTC 2016

Hi Atin,

All nodes are running 3.5.8 – the probe sequence is:
172.31.30.64
172.31.27.27 (node having issue)
172.31.26.134 (node the peer probe is ran on)
172.31.19.46

I’ve sent the logs directly as they push this message over the size limit.

look forward to your reply,

Tommy

This indicates the peer handshaking didn't go through properly and your cluster is messed up. Are you running 3.5.8 version in all the nodes? Could you get me the glusterd log from all the nodes and mention the peer probe sequence? I'd be able to look at it tomorrow only and get back.

Hi All,

I’m running GlusterFS on a cluster hosted in AWS. I have a script which provisions my instances and thus will set up GlusterFS (specifically: glusterfs 3.5.8).

My issue is that this only works ~50% of the time and the other 50% of the time one of the peers will be ‘stuck’ in the following state:
root at ip-xx-xx-xx-1:/home/ubuntu# gluster peer status
Number of Peers: 3

Hostname: xx.xx.xx.2
Uuid: 3b4c1fb9-b325-4204-98fd-2eb739fa867f
State: Peer in Cluster (Connected)

Hostname: xx.xx.xx.3
Uuid: acfc1794-9080-4eb0-8f69-3abe78bbee16
State: Sent and Received peer request (Connected)

Hostname: xx.xx.xx.4
Uuid: af33463d-1b32-4ffb-a4f0-46ce16151e2f
State: Peer in Cluster (Connected)

Running gluster peer status on the instance that is affected yields:

root at ip-xx-xx-xx-3:/var/log/glusterfs# gluster peer status
Number of Peers: 1

Hostname: xx.xx.xx.1
Uuid: c4f17e9a-893b-48f0-a014-1a05cca09d01
State: Peer is connected and Accepted (Connected)

Of which the status (Connected) in this case, will fluctuate between ‘Connected’ and ‘Disconnected’.

I have been unable to locate the cause of this issue. Has this been encountered before, and if so is there a general fix? I haven’t been able to find anything as of yet.

Many thanks,

Tommy
