I recently upgraded my Distributed-Replicate cluster from Gluster 7.9 to 8.3 on CentOS7 using the CentOS Storage SIG packages. I had geo-replication syncing properly before the upgrade, but not it is not working after.
After I had upgraded both master and slave clusters I attempted to start geo-replication again, but it goes to faulty quickly:
[root@storage01 ~]# gluster volume geo-replication storage geoaccount@10.0.231.81::pcic-backup start
Starting geo-replication session between storage & geoaccount@10.0.231.81::pcic-backup has been successful\

I went through the gsyncd logs and see it attempts to go back through the changlogs - which would make sense - but fails:

It seems like there is an issue selecting the changelogs - perhaps similar to this issue? https://github.com/gluster/glusterfs/issues/1766

Any ideas on where to debug this? I'd prefer not to have to remove and re-sync everything as there is about 240TB on the cluster...
