as someone with hardware on the way to build a 3 node HCI cluster with only 2 2tb SSDs per node this problem concerns me, I sometimes worry about the complexity glusterfs adds to the mix and how how difficult it can be to manage when things go wrong.

Ive been following this thread and feel for you. You must be getting tired, been there done that and don't wish it upon anyone. I hope you get your environment back in working order soon and at some point discover what went wrong to cause this problem.

I've just gotten back to where hsoted-engine --vm-status does (eventually) return some output other than the ha-agent or storage is down error. It does currently take up to two minutes, and the last run returned stale data.

Gluster-wise, gluster volume heal <volume> info shows the three volumes with all bricks are all showing 0 entries (and return quickly). The 4th volume missing one brick (but still has two replicas) does return entries, and is currently taking a very long time to come back with them.

Making progress toward getting it online again...Don't know why I get stale data in hosted-engine --vm-status or how to overcome that...

I believe the gluster data store for the engine is up and working correctly. The rest are not mounted, as the engine hasn't managed to start correctly yet. I did perform the copy-a-junk-file into the data store, then check to ensure its there on another host, then delete that and see that it disappeared on the first host; it passed that test. Here's the info and status. (I have NOT performed the steps that Krutika and Ravishankar suggested yet, as I don't have my data volumes working again yet.

hosted-engine --deploy failed (would not come up on my existing gluster storage). However, I realized no changes were written to my existing storage. So, I went back to trying to get my old engine running.

hosted-engine --vm-status is now taking a very long time (5+minutes) to return, and it returns stail information everywhere. I thought perhaps the lockspace is corrupt, so tried to clean that and metadata, but both are failing (--cleam-metadata has hung and I can't even ctrl-c out of it).

How can I reinitialize all the lockspace/metadata safely? There is no engine or VMs running currently....

I think the first thing to make sure is that your storage is up and running. So can you mount the gluster volumes and able to access the contents there?
Please provide the gluster volume info and gluster volume status of the volumes that you're using.

Well, things went from bad to very, very bad....

It appears that during one of the 2 minute lockups, the fencing agents decided that another node in the cluster was down. As a result, 2 of the 3 nodes were simultaneously reset with fencing agent reboot. After the nodes came back up, the engine would not start. All running VMs (including VMs on the 3rd node that was not rebooted) crashed.

I've now been working for about 3 hours trying to get the engine to come up. I don't know why it won't start. hosted-engine --vm-start says its starting, but it doesn't start (virsh doesn't show any VMs running). I'm currently running --deploy, as I had run out of options for anything else I can come up with. I hope this will allow me to re-import all my existing VMs and allow me to start them back up after everything comes back up.

I do have an unverified geo-rep backup; I don't know if it is a good backup (there were several prior messages to this list, but I didn't get replies to my questions. It was running in what I believe to be "strange", and the data directories are larger than their source).

I'll see if my --deploy works, and if not, I'll be back with another message/help request.

When the dust settles and I'm at least minimally functional again, I really want to understand why all these technologies designed to offer redundancy conspired to reduce uptime and create failures where there weren't any otherwise. I thought with hosted engine, 3 ovirt servers and glusterfs with minimum replica 2+arb or replica 3 should have offered strong resilience against server failure or disk failure, and should have prevented / recovered from data corruption. Instead, all of the above happened (once I get my cluster back up, I still have to try and recover my webserver VM, which won't boot due to XFS corrupt journal issues created during the gluster crashes). I think a lot of these issues were rooted from the upgrade from 4.1 to 4.2.

[12127.466494] perf: interrupt took too long (8263 > 8150), lowering kernel.perf_event_max_sample_rate to 24000

--------------------
I think this is the cause of the massive ovirt performance issues irrespective of gluster volume. At the time this happened, I was also ssh'ed into the host, and was doing some rpm querry commands. I had just run rpm -qa |grep glusterfs (to verify what version was actually installed), and that command took almost 2 minutes to return! Normally it takes less than 2 seconds. That is all pure local SSD IO, too....

I'm no expert, but its my understanding that anytime a software causes these kinds of issues, its a serious bug in the software, even if its mis-handled exceptions. Is this correct?
