I've seen that problem in other threads, the common denominator was "nfs on top of gluster". So if you have this setup, then it's a known problem. Or you should double check if you hosts have different ids otherwise they would be trying to acquire the same lock. --Jirka On 06/06/2014 08:03 AM, Andrew Lau wrote:

Hi Ivan,

Thanks for the in depth reply.

I've only seen this happen twice, and only after I added a third host to the HA cluster. I wonder if that's the root problem.

Have you seen this happen on all your installs or only just after your manual migration? It's a little frustrating this is happening as I was hoping to get this into a production environment. It was all working except that log message :(

Thanks, Andrew

Hi Andrew,

this is something that I saw in my logs too, first on one node and then on the other three. When that happend on all four of them, engine was corrupted beyond repair.

First of all, I think that message is saying that sanlock can't get a lock on the shared storage that you defined for the hostedengine during installation. I got this error when I've tried to manually migrate the hosted engine. There is an unresolved bug there and I think it's related to this one:

[Bug 1093366 - Migration of hosted-engine vm put target host score to zero] https://bugzilla.redhat.com/show_bug.cgi?id=1093366

This is a blocker bug (or should be) for the selfhostedengine and, from my own experience with it, shouldn't be used in the production enviroment (not untill it's fixed).

Nothing that I've done couldn't fix the fact that the score for the target node was Zero, tried to reinstall the node, reboot the node, restarted several services, tailed a tons of logs etc but to no avail. When only one node was left (that was actually running the hosted engine), I brought the engine's vm down gracefully (hosted-engine --vm-shutdown I belive) and after that, when I've tried to start the vm - it wouldn't load. Running VNC showed that the filesystem inside the vm was corrupted and when I ran fsck and finally started up - it was too badly damaged. I succeded to start the engine itself (after repairing postgresql service that wouldn't want to start) but the database was damaged enough and acted pretty weird (showed that storage domains were down but the vm's were running fine etc). Lucky me, I had already exported all of the VM's on the first sign of trouble and then installed ovirt-engine on the dedicated server and attached the export domain.

So while really a usefull feature, and it's working (for the most part ie, automatic migration works), manually migrating VM with the hosted-engine will lead to troubles.

I hope that my experience with it, will be of use to you. It happened to me two weeks ago, ovirt-engine was current (3.4.1) and there was no fix available.

Regards,

Ivan

It also appears to occur on the other hosts in the cluster, except the host which is running the hosted-engine. So right now 3 servers, it shows up twice in the engine UI.

The engine VM continues to run peacefully, without any issues on the host which doesn't have that error.

I'm really having a hard time finding out why it's happening.. If I set the cluster to global for a minute or two, the scores will reset back to 2400. Set maintenance mode to none, and all will be fine until a migration occurs. It seems it tries to migrate, fails and sets the score to 0 permanently rather than the 10? minutes mentioned in one of the ovirt slides. When I have two hosts, it's score 0 only when a migration occurs. (Just on the host which doesn't have engine up). The score 0 only happens when it's tried to migrate when I set the host to local maintenance. Migrating the VM from the UI has worked quite a few times, but it's recently started to fail. When I have three hosts, after 5~ mintues of them all up the score will hit 0 on the hosts not running the VMs. It doesn't even have to attempt to migrate before the score goes to 0. Stopping the ha agent on one host, and "resetting" it with the global maintenance method brings it back to the 2 host scenario above. I may move on and just go back to a standalone engine as this is not getting very much luck.. On Tue, Jun 10, 2014 at 3:11 PM, combuster <combuster@archlinux.us> wrote:

Does it just happen without any procedure on the engine itself? Is the score 0 for just one node, or two of three of them?

I just ran a few extra tests, I had a 2 host, hosted-engine running for a day. They both had a score of 2400. Migrated the VM through the UI multiple times, all worked fine. I then added the third host, and that's when it all fell to pieces. Other two hosts have a score of 0 now.

I'm also curious, in the BZ there's a note about:

where engine-vm block connection to storage domain(via iptables -I INPUT -s sd_ip -j DROP)

What's the purpose for that?

Ok, I thought I was doing something wrong yesterday and just tore down my 3-node cluster with the hosted engine and started rebuilding. I was seeing essentially the same thing, a score of 0 on the VMs not running the engine, it wouldn't allow migration of the hosted engine. I played with all things related to setting maintenance and rebooting hosts, nothing brought them up to a point where I could migrate the hosted engine. I thought it was related to ovirt messing up when deploying the other hosts (I told it not to modify the firewall that I disabled, but the deploy process forcibly reenabled the firewall which gluster really didn't like). Now after reading this it appears my assumption may be false. Previously a 2-node cluster I had worked fine, but I wanted to go to 3-nodes so I could enable quorum on gluster to not risk split-brain issues. -Brad On 6/10/14 1:19 AM, Andrew Lau wrote:

Hi Ivan,

Thanks for the in depth reply.

I've only seen this happen twice, and only after I added a third host to the HA cluster. I wonder if that's the root problem. It shouldn't be if a shared storage that vm is residing on is accessible by a third node in the cluster.

Have you seen this happen on all your installs or only just after your manual migration? It's a little frustrating this is happening as I was hoping to get this into a production environment. It was all working except that log message :( Just after manual migration, then things went all to ... My strong recommendation is not to use self hosted engine feature for production

Hi Andrew,

this is something that I saw in my logs too, first on one node and then on the other three. When that happend on all four of them, engine was corrupted beyond repair.

First of all, I think that message is saying that sanlock can't get a lock on the shared storage that you defined for the hostedengine during installation. I got this error when I've tried to manually migrate the hosted engine. There is an unresolved bug there and I think it's related to this one:

[Bug 1093366 - Migration of hosted-engine vm put target host score to zero] https://bugzilla.redhat.com/show_bug.cgi?id=1093366

This is a blocker bug (or should be) for the selfhostedengine and, from my own experience with it, shouldn't be used in the production enviroment (not untill it's fixed).

Nothing that I've done couldn't fix the fact that the score for the target node was Zero, tried to reinstall the node, reboot the node, restarted several services, tailed a tons of logs etc but to no avail. When only one node was left (that was actually running the hosted engine), I brought the engine's vm down gracefully (hosted-engine --vm-shutdown I belive) and after that, when I've tried to start the vm - it wouldn't load. Running VNC showed that the filesystem inside the vm was corrupted and when I ran fsck and finally started up - it was too badly damaged. I succeded to start the engine itself (after repairing postgresql service that wouldn't want to start) but the database was damaged enough and acted pretty weird (showed that storage domains were down but the vm's were running fine etc). Lucky me, I had already exported all of the VM's on the first sign of trouble and then installed ovirt-engine on the dedicated server and attached the export domain.

So while really a usefull feature, and it's working (for the most part ie, automatic migration works), manually migrating VM with the hosted-engine will lead to troubles.

I hope that my experience with it, will be of use to you. It happened to me two weeks ago, ovirt-engine was current (3.4.1) and there was no fix available.

Ivan

Hi,

I'm seeing this weird message in my engine log

It also appears to occur on the other hosts in the cluster, except the host which is running the hosted-engine. So right now 3 servers, it shows up twice in the engine UI.

The engine VM continues to run peacefully, without any issues on the host which doesn't have that error.

Any ideas? _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
