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
