I haven't done anything more than peer thus far, so I'm a bit confused as to how the volume info fits in, can you expand on this a bit?

Failed commits? Is this split brain on the replica volumes? I don't get any return from 'gluster volume heal <volname> info' on all the replica volumes, but if I try a gluster volume heal <volname> full I get: 'Launching heal operation to perform full self heal on volume <volname> has been unsuccessful'.

forget about this. it is not for metadata selfheal .

I have 5 volumes total.

'Replica 3' volumes running on gluster01/02/03:

vm-storage

iso-storage

export-domain-storage

env-modules

And one distributed only volume 'storage' info shown below:

So far between gluster01/02 and gluster03/04 the configs are the same, although the ordering is different for some of the features.

On gluster05/06 the ordering is different again, and the quota-version=0 instead of 1.

This is why the peer shows as rejected. Can you check the op-version of all the glusterd including the one which is in reject state. you can find out the op-version here in  /var/lib/glusterd/glusterd.info

Also, I forgot to mention that when I initially peer'd the two new hosts, glusterd crashed on gluster03 and had to be restarted (log attached) but has been fine since.

Thanks,

Hello,

I upgraded from 3.6.6 to 3.7.6 a couple weeks ago. I just peered 2 new nodes to a 4 node cluster and gluster peer status is:

Looks like your configuration files are mismatching, ie the checksum calculation differs on this two node than the others,

Did you had any failed commit ?

Compare your /var/lib/glusterd/<volname>/info of the failed node against good one, mostly you could see some difference.

can you paste the /var/lib/glusterd/<volname>/info ?

Regards
Rafi KC

I followed the write-up here: http://www.gluster.org/community/documentation/index.php/Resolving_Peer_Rejected and the two new nodes peer'd properly but after a reboot of the two new nodes I'm seeing the same Peer Rejected (Connected) State.

I've attached logs from an existing node, and the two new nodes.

Thanks for any suggestions,

Steve
