Hi all,

For the records, I had to remove manually the conflicting directory and ts respective gfid from the arbiter volume:

 getfattr -m . -d -e hex e1c80750-b880-495e-9609-b8bc7760d101/ha_agent

That gave me the gfid: 0x277c9caa9dce4a17a2a93775357befd5

Then cd .glusterfs/27/7c

rm -rf 277c9caa-9dce-4a17-a2a9-3775357befd5 (or move it out of there)

Triggerred heal: gluster volume heal engine

Then all ok:

gluster volume heal engine info
Brick gluster0:/gluster/engine/brick
Status: Connected
Number of entries: 0

Brick gluster1:/gluster/engine/brick
Status: Connected
Number of entries: 0

Brick gluster2:/gluster/engine/brick
Status: Connected
Number of entries: 0

Thanx.

When I shutdown host3 then no split brain is reported from the remaining two hosts. When I power up host3 then I receive the mentioned split brain and host3 logs the following at ovirt-hosted-engine-ha/agent.log

Hi All,

I have a 3 node ovirt 4.1 setup. I lost one node due to raid controller issues. Upon restoration I have the following split brain, although the hosts have mounted the storage domains:

It is definitely on gluster side. You could try to use

gluster volume heal engine split-brain latest-mtime /e1c80750-b880-495e-9609-b8bc7760d101/ha_agent


I also added gluster developers to that thread, so they may provide you with better advices.
