[ovirt-users] VM HostedEngie is down. Exist message: internal error Failed to acquire lock error -243

[combuster]

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* <https://bugzilla.redhat.com/show_bug.cgi?id=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
