Hello,
So I'm seeing a rejected peer with 3.12.6. This is with a replica 3 volume.
It actually began as the same problem with a different peer. I noticed with (call it) gluster-2, when I couldn't make a new volume. I compared /var/lib/glusterd between them, and found that somehow the options in one of the vols differed. (I suspect this was due to attempting to create the volume via the Ovirt GUI; suffice to say I'm not using it for things like this in the future.) So I stopped the daemons and corrected that (gluster-2 had a tiering entry the others didn't).
When you say the others didn't how many peers are you talking about? Are they all running 3.12.6? We had a bug https://bugzilla.redhat.com/show_bug.cgi?id=1544637 which could lead you to such situations but that has been fixed in 3.12.6. So if all of the nodes are running with the same version i.e. 3.12.6 and the cluster.op-version is set to latest, then ideally you shouldn't see this problem. Could you clarify?
Started things back up and now gluster-3 is being rejected by the other two. The error is below.
I'm tempted to repeat - down things, copy the checksum the "good" ones agree on, start things; but given that this has turned into a balloon-squeezing exercise, I want to make sure I'm not doing this the wrong way.
Yes, that's the way. Copy /var/lib/glusterd/vols/<volname>/ from the good node to the rejected one and restart glusterd service on the rejected peer.
What is the currently accepted best method for fixing this?
And given that this happened on a nearly brand-new deployment, it worries me a bit that this happened while nothing hinky was going on - I installed Gluster manually, but the rest of the systems management has been via Ovirt. Has anyone else seen issues with this?
Thanks,
