never mind. I do not have enough time to debug why basic commands of gluster do not work on production server. It was enough of tonight's system freeze due to not documented XFS settings MUST have to run glusterfs with XFS. I'll keep to EXT4 better. Anyway XFS for bricks did not solve my previous problem.
To solve split-brain this time, I've restored VM from backup.

Thanx for pointing out...but doesn't seem to work... or i am too sleepy due to problems with glusterfs and debian8 in other topic which i'm fighting for month..root@stor1:~# gluster volume heal HA-2TB-TT-Proxmox-cluster split-brain source-brick stor1:HA-2TB-TT-Proxmox-cluster/2TB /images/124/vm-124-disk-1.qcow2Usage: volume heal <VOLNAME> [{full | statistics {heal-count {replica <hostname:brickname>}} |info {healed | heal-failed | split-brain}}]seems like wrong command...2015-07-14 21:23 GMT+03:00 Joe Julian <joe@xxxxxxxxxxxxxxxx>:On 07/14/2015 11:19 AM, Roman wrote:
https://github.com/gluster/glusterfs/blob/master/doc/features/heal-info-and-split-brain-resolution.mdHi,
played with glusterfs tonight and tried to use recommended XFS for gluster.. first try was pretty bad and all of my VM-s hanged (XFS wants allocsize=64k to create qcow2 files, which i didn't know about and tried to create VM on XFS without this config line in fstab, which lead to a lot of IO-s and qemu says it got time out while creating the file)..
now i've got this:
Brick stor1:/exports/HA-2TB-TT-Proxmox-cluster/2TB/
/images/124/vm-124-disk-1.qcow2 - Is in split-brain
Number of entries: 1
Brick stor2:/exports/HA-2TB-TT-Proxmox-cluster/2TB/
/images/124/vm-124-disk-1.qcow2 - Is in split-brain
ok. what next?
I've deleted one of files, it didn't help. even more, selfheal restored the file on node, where i deleted it... and still split-brain.
how to fix?
