I changed to replication to use the root user and re-created the replication with “create force”. Now the files and folders were replicated, and the permission denied, and New folder error disappeared, but old files are not deleted.
Looks like the history crawl is in some kind of a loop:

Any ideas how to resolve this without re-creating everything again? Can I reset the changelog history?

I don’t configure the permissions of /bricks/brick1/brick/.glusterfs. I don’t even see it on the local GlusterFS mount.
Not sure why the permissions are configured with S and the AD group…

Yeah right. I get permission denied.

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 point. Could this be an issue? Should I avoid configuring the permissions on .glusterfs and below?

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?
Thanks,

Ok. It happens on all slave nodes (and on the interimmaster as well).
It’s like I assumed. These are the logs of one of the slaves:

Subject: Re: [Gluster-users] [geo-rep] Replication faulty - gsyncd.log OSError: [Errno 13] Permission denied
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.

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.

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
