However, the strange thing is that I could replicate new files and folders
before. The replication is broken since the “New folder” was created.
These are the permissions on a dev/test system:

I’ve configured an AD group, SGID bit, and ACLs via Ansible on the local mount

I think I am get what's happening. The geo-rep session is non-root.
Could you do readlink on brick path mentioned above
/bricks/brick1/brick/.glusterfs/29/d1/29d1d60d-1ad6-45fc-87e0-93d478f7331e
from a geaccount user and see if you are getting "Permission Denied" errors?

The problem occured on slave side whose error is propagated to master. Mostly
any traceback with repce involved is related to problem in slave. Just check
few lines above in the log to find the slave node, the crashed worker is
connected to and get geo replication logs to further debug.

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.

Christian Kotte
