Expand existing gluster storage in ovirt 4.2/4.3
by adrianquintero＠gmail.com
Hello,
I have a 3 node ovirt 4.3 cluster that I've setup and using gluster (Hyperconverged setup)
I need to increase the amount of storage and compute so I added a 4th host (server4.example.com) if it is possible to expand the amount of bricks (storage) in the "data" volume?
I did some research and from that research the following caught my eye: old post "https://medium.com/@tumballi/scale-your-gluster-cluster-1-node-at-a-time-..."
So the question is, if taking that approach feasible? , is it even possible an oVirt point of view?
---------------------------
My gluster volume:
---------------------------
Volume Name: data
Type: Replicate
Volume ID: 003ffea0-b441-43cb-a38f-ccdf6ffb77f8
Status: Started
Snapshot Count: 0
Number of Bricks: 1 x (2 + 1) = 3
Transport-type: tcp
Bricks:
Brick1: server1.example1.com:/gluster_bricks/data/data
Brick2: server2.example.com:/gluster_bricks/data/data
Brick3: server3.example.com:/gluster_bricks/data/data (arbiter)

Re: Windows Guest timezone
by Strahil
I used to set windows machines to use HW clock in UTC , which helped for dual-boot hardware machines.
Can't you use that approach and never worry about DST?

Windows Guest timezone
by Stefano Danzi
Hello!
I've a guest windows VM (Server 2016) and hardware clock in oVirt
machine configuration is GMT +1.
Now we are DST period and machine timezone is GMT +2. Engine Dashboard
warn me about timezone
mismatch between configuration and running VM. I can't see a setting to
enable DST on emulated hardware.
Some ideas?

change self-hosted engine storage domain
by jason.cox＠harris.com
Is it possible to change a self-hosted engine's storage domain's settings?
I setup a 3-node ovirt + gluster cluster with a dedicated 'engine' storage domain. I can see through the administration portal that the engine storage domain is using a single gluster host and no backup volfile servers. The single gluster host that the engine storage domain settings refer to had to be removed, so now I'm getting issues where VDSM is reporting that it cannot get the volume file information for the engine storage domain.
I'm not sure how to go about changing the settings since the only way I've seen how to do this is through the administration portal, which relies on the engine VM (and its storage) being available.
What I'd like to do is change the storage domain's path and add mount options for the backup volfile servers.

accessing ovirt-image-repository from behind proxy?
by Jarosław Prokopowski
Hi,
Is there a way to connect to ovirt-image-repository from ovirt-engine through proxy server?
I tried to set http_proxy in /etc/profile of the hosted-engine VM and restarted the VM but it does not help...
Errors I get while testing the connection:
2019-04-10 12:36:49,590+03 ERROR [org.ovirt.engine.core.bll.storage.repoimage.GetImagesListQuery] (default task-3) [58f90541-0212-4f1e-9b14-eafc9a8237b9] Failed to retrieve image list: Connec tion timed out (Connection timed out)
