I'm wondering if anyone has any tips to improve file/directory operations
in HCI replica 3 (no arbtr) configuration with SSDs and 10Gbe storage
network.
I am running stock optimize for virt store volume settings currently and am
wondering what if any improvements I can make for VM write speed and
"Host host1.example.com cannot access the Storage Domain(s) attached to the
Data Center Default-DC1."
Can you check the vdsm logs from this host to check why the storage domains
are not attached?

I was able to use the brick reset process to change hostnames of all
gluster volumes. Traffic is now flowing through my 10gig gluster network.
Thanks for the assistance with this all!

Thanks for the info, but where does it get the new hostname from? Do I
need to change the actual server hostnames of my nodes? If I were to do
that then the hosts would not be accessible due to the fact that the
gluster storage subnet is isolated.
I guess I'm confused about what gdeploy does
The reset-brick and replace-brick affects only one brick and notifies the
gluster cluster that a new hostname:/brick_path is being used.
Of course, you need a hostname that resolves to the IP that is on the storage
network.

Check why the sanlock.service reports no pid.
Also check the logs of the broker and agent located at
/var/log/ovirt-hosted-engine-ha
You might have to increase the verbosity of the broker and agent.

Sahina,
Thank you very much for the explanation. I definitely do want Gluster
traffic on my 10gig network but am being extra cautious because there are
live VMs on the volumes.
This is my current configuration
host0.blah.example.com: 10.11.0.220 (gluster interface: 10.12.0.220)

For example my gluster network IP is 10.10.10.1/24 and the /etc/hosts entry is:
10.10.10.1 gluster1.localdomain gluster1
Then I did 'gluster volume replace-brick ovirt1:/gluster_bricks/data/data
gluster1:/gluster_bricks/data/data commit'
So you use a hostname that is resolved either by DNS or
10 matches
