We currently have a small pilot gluster setup as Replica 2 + 1 (arbiter)
As a DR test we decided to see that to see what would happen when
taking one of the replicas offline. For the first couple of hours
everything seemed fine and then one of my colleagues tried to a
directory with files via samba from a windows client by using robocopy.
At this point it starting to go wrong. The brick went offline, I could
force it online but when trying to manipulate files on the volume the
brick kept going offline.
What do you mean by the brick going offline? The brick gets killed? What
does the brick log say?
Some Examples of trying to manipulate the files from the mounted
gluster volume:
rm -rf a Directory: "Directory not empty"
on an empty directory ls -la : "total 0" ( didn't show "." or ".." )
After bringing the partner replica up the brick on the system that was
never shutdown kept going offline. In the end I ended up restoring the
volume from a gluster snapshot from the night before and then
everything seemed fine again.
This morning I was made aware that creating a new directory via samba
resulted in 5 New folders being created. Restarting glusterd has made
the issue go away for now.
Are you saying that each brick has the same directory created 5 times?

This is on Centos 7.3 with gluster 3.10.3-1 and samba 4.4.4-14
Can anyone help ?
Thanks
