Hi Atin, Setting 'state=3' on the instances and restarting the service seems to have fixed the problem. Is this an 'issue' with glusterfs? I will implement an automated solution for my problem, just would be good to know if this is something that will be patched in the future? Thanks, Tommy -----Original Message----- From: Atin Mukherjee [mailto:amukherj@xxxxxxxxxx] Sent: 22 March 2016 13:10 To: Yardley, Tommy (UK Guildford); gluster-users@xxxxxxxxxxx Subject: Re: GlusterFS cluster peer stuck in state: Sent and Received peer request (Connected) Tommy, It seems like that there were frequent disconnect events which may have caused the peer handshaking to remain incomplete and leading to an inconsistency in the cluster state. Further follow up questions: 1. Restarting glusterd instances doesn't solve the problem? 2. If answer to 1 is yes can we try to set state=3 in all the /var/lib/glusterd/peers/<UUID> files and then restart glusterd to see whether the problem persists? If the above still doesn't solve the problem output of 'cat /var/lib/glusterd/peers/*' from all the nodes should help us in figuring out the correct workaround. ~Atin On 03/22/2016 02:51 PM, Atin Mukherjee wrote: > Gaurav is looking into it and he will get back with his analysis. > > ~Atin > > On 03/22/2016 02:42 PM, tommy.yardley@xxxxxxxxxxxxxx wrote: >> Hi, >> >> Is anyone able to help with this issue? >> >> Thanks, >> Tommy >> >> -----Original Message----- >> From: gluster-users-bounces@xxxxxxxxxxx >> [mailto:gluster-users-bounces@xxxxxxxxxxx] On Behalf Of >> tommy.yardley@xxxxxxxxxxxxxx >> Sent: 17 March 2016 08:49 >> To: gluster-users@xxxxxxxxxxx >> Subject: Re: GlusterFS cluster peer stuck in state: >> Sent and Received peer request (Connected) >> >> Hi, >> >> Sorry I had sent them directly to Atin >> >> I've trimmed down the larger log files a bit and attached all of them to this email. >> >> Many thanks, >> Tommy >> >> -----Original Message----- >> From: Gaurav Garg [mailto:ggarg@xxxxxxxxxx] >> Sent: 17 March 2016 07:07 >> To: Yardley, Tommy (UK Guildford) >> Cc: gluster-users@xxxxxxxxxxx >> Subject: Re: GlusterFS cluster peer stuck in state: >> Sent and Received peer request (Connected) >> >>>>> I’ve sent the logs directly as they push this message over the size limit. >> >> Where have you send logs. i could not able to find. could you send glusterd logs so that we can start analyzing this issue. >> >> Thanks, >> >> Regards, >> Gaurav >> >> ----- Original Message ----- >> From: "Atin Mukherjee" <amukherj@xxxxxxxxxx> >> To: "tommy yardley" <tommy.yardley@xxxxxxxxxxxxxx>, >> gluster-users@xxxxxxxxxxx >> Sent: Wednesday, March 16, 2016 5:49:05 PM >> Subject: Re: GlusterFS cluster peer stuck in state: >> Sent and Received peer request (Connected) >> >> I couldn't look into this today, sorry about that.
