_______________________________________________Hi,
Any idea how to troubleshoot this?
New folders and files were created on the master and the replication went faulty. They were created via Samba.
Version: GlusterFS 4.1.3
[root@master]# gluster volume geo-replication status

The following error is repeatedly logged in the gsyncd.logs:

The permissions look fine. The replication is done via geo user instead of root. It should be able to read, but I’m not sure if the syncdaemon runs under geoaccount!?

It could be possible that the folder was renamed. I had 3 similar issues since I migrated to GlusterFS 4.x but couldn’t investigate much. I needed to completely wipe GlusterFS and geo-repliction to get rid of this error…
Any help is appreciated.
