Re: [ovirt-users] hyperconverged question

Jim - result of this test...engine crashed but all VM's on the gluster domain (backed by the same physical nodes/hardware/gluster process/etc) stayed up fine I guess there is some functional difference between 'backupvolfile-server' and 'backup-volfile-servers'? Perhaps try latter and see what

Re: [ovirt-users] hyperconverged question

Jim - One thing I noticed is that, by accident, I used 'backupvolfile-server=node2:node3' which is apparently a supported setting. It would appear, by reading the man page of mount.glusterfs, the syntax is slightly different. not sure if my setting being different has different impacts

Re: [ovirt-users] hyperconverged question

Jim - here is my test: - All VM's on node2: hosted engine and 1 test VM - Test VM on gluster storage domain (with mount options set) - hosted engine is on gluster as well, with settings persisted to hosted-engine.conf for backupvol All VM's stayed up. Nothing in dmesg of the test vm indicating

Re: [ovirt-users] hyperconverged question

I can confirm that I did set it up manually, and I did specify backupvol, and in the "manage domain" storage settings, I do have under mount options, backup-volfile-servers=192.168.8.12:192.168.8.13 (and this was done at initial install time). The "used managed gluster" checkbox is NOT checked,

@ Jim - here is my setup which I will test in a few (brand new cluster) and report back what I found in my tests - 3x servers direct connected via 10Gb - 2 of those 3 setup in ovirt as hosts - Hosted engine - Gluster replica 3 (no arbiter) for all volumes - 1x engine volume gluster replica 3

Re: [ovirt-users] hyperconverged question

So, after reading the first document twice and the 2nd link thoroughly once, I believe that the arbitrator volume should be sufficient and count for replica / split brain. EG, if any one full replica is down, and the arbitrator and the other replica is up, then it should have quorum and all

Thank you! I created my cluster following these instructions: https://www.ovirt.org/blog/2016/08/up-and-running-with-ovirt-4-0-and-gluster-storage/ (I built it about 10 months ago) I used their recipe for automated gluster node creation. Originally I thought I had 3 replicas, then I started

These can get a little confusing but this explains it best: https://gluster.readthedocs.io/en/latest/Administrator%20Guide/arbiter-volumes-and-quorum/#replica-2-and-replica-3-volumes Basically in the first paragraph they are explaining why you cant have HA with quorum for 2 nodes. Here is another

[ovirt-users] Slow booting host - restart loop

Hi everyone, I installed 2 hosts on a new cluster and the servers take a really long to boot up (about 8 minutes). When a host crashes or is powered off the ovirt-manager starts it via power management, since the servers takes all that time to boot up the ovirt-manager thinks it failed to start

Thank you! I created all the VMs using the sparce allocation method. I wanted a method that would create disks that did not immediately occupy their full declared size (eg, allow overcommit of disk space, as most VM hard drives are 30-50% empty for their entire life). I kinda figured that it

Re: [ovirt-users] hyperconverged question

yes, that is the same option i was asking about. Apologies that i had mentioned a different name. So, ovirt will automatically detect it if you select the option 'use managed gluster volume'. While adding a storage domain after specifying the host , you could just select the checkbox and that

Are you referring to "Mount Options" - > http://i.imgur.com/bYfbyzz.png Then no, but that would explain why it wasnt working :-). I guess I had a silly assumption that oVirt would have detected it and automatically taken up the redundancy that was configured inside the replica set / brick

Hi Charles, One question, while configuring a storage domain you are saying "host to use: " node1, then in the connection details you say node1:/data. What about the backup-volfile-servers option in the UI while configuring storage domain? Are you specifying that too? Thanks kasturi

Re: [ovirt-users] hyperconverged question

@ Jim - you have only two data volumes and lost quorum. Arbitrator only stores metadata, no actual files. So yes, you were running in degraded mode so some operations were hindered. @ Sahina - Yes, this actually worked fine for me once I did that. However, the issue I am still facing, is when I

Re: [ovirt-users] hyperconverged question

To the OP question, when you set up a gluster storage domain, you need to specify backup-volfile-servers=: where server2 and server3 also have bricks running. When server1 is down, and the volume is mounted again - server2 or server3 are queried to get the gluster volfiles. @Jim, if this does not

Re: [ovirt-users] hyperconverged question

If gluster drops in quorum so that it has less votes than it should it will stop file operations until quorum is back to normal.If i rember it right you need two bricks to write for quorum to be met and that the arbiter only is a vote to avoid split brain. Basically what you have is a raid5
