This is replica 2, only , with following settings
Options Reconfigured:
performance.quick-read: off
performance.read-ahead: off
performance.io-cache: off
performance.stat-prefetch: off
cluster.eager-lock: enable
network.remote-dio: enable
cluster.quorum-type: fixed
Not sure why you have set this option.
Ideally replica 3 or arbiter volumes are recommended for
gluster+ovirt use. (client) quorum does not make sense for a 2 node
setup. I have a detailed write up here which explains things
http://gluster.readthedocs.org/en/latest/Administrator%20Guide/arbiter-volumes-and-quorum/
which explains things.
cluster.server-quorum-type: none
storage.owner-uid: 36
storage.owner-gid: 36
cluster.quorum-count: 1
cluster.self-heal-daemon: enable
If I'll create "ids" file manually ( eg. " sanlock direct init -s
3c34ad63-6c66-4e23-ab46-084f3d70b147:0:/STORAGES/g1r5p3/GFS/3c34ad63-6c66-4e23-ab46-084f3d70b147/dom_md/ids:0
" ) on both bricks,
vdsm is writing only to half of them ( that with 2 links = correct
)
"ids" file has correct permittions, owner, size on both bricks.
brick 1: -rw-rw---- 1 vdsm kvm 1048576 2. bře 18.56
/STORAGES/g1r5p3/GFS/3c34ad63-6c66-4e23-ab46-084f3d70b147/dom_md/ids
- not updated
Okay, so this one has link count =1 which means the .glusterfs
hardlink is missing. Can you try deleting this file from the brick
and perform a stat on the file from the mount? That should heal (i.e
recreate it ) on this brick from the other brick with the
appropriate .glusterfs hard link.
brick
2: -rw-rw---- 2 vdsm kvm 1048576 3. bře 10.16
/STORAGES/g1r5p3/GFS/3c34ad63-6c66-4e23-ab46-084f3d70b147/dom_md/ids
- is continually updated
What happens when I'll restart vdsm ? Will oVirt storages go to
"disable " state ??? = disconnect VMs storages ?
No idea on this one...

How can I fix it ?? - online !
Ravi?
Is this the case in all 3 bricks of the replica?
BTW, you can just stat the file on the brick and see the link
count (it must be 2) instead of running the more expensive find
command.
