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,

It?s like I assumed. These are the logs of one of the slaves:

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

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

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"

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
