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.... --Jim On Tue, May 29, 2018 at 9:33 PM, Jim Kusznir <jim@palousetech.com> wrote:
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.

-------------------- 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?

Thank you for your response.
I have 4 gluster volumes. 3 are replica 2 + arbitrator. replica bricks are on ovirt1 and ovirt2, arbitrator on ovirt3. The 4th volume is replica 3, with a brick on all three ovirt machines.
The first 3 volumes are on an SSD disk; the 4th is on a Seagate SSHD (same in all three machines). On ovirt3, the SSHD has reported hard IO failures, and that brick is offline. However, the other two replicas are fully operational (although they still show contents in the heal info command that won't go away, but that may be the case until I replace the failed disk).
What is bothering me is that ALL 4 gluster volumes are showing horrible performance issues. At this point, as the bad disk has been completely offlined, I would expect gluster to perform at normal speed, but that is definitely not the case.
I've also noticed that the performance hits seem to come in waves: things seem to work acceptably (but slow) for a while, then suddenly, its as if all disk IO on all volumes (including non-gluster local OS disk volumes for the hosts) pause for about 30 seconds, then IO resumes again. During those times, I start getting VM not responding and host not responding notices as well as the applications having major issues.
I've shut down most of my VMs and am down to just my essential core VMs (shedded about 75% of my VMs). I still am experiencing the same issues.
Am I correct in believing that once the failed disk was brought offline that performance should return to normal?

I would check disks status and accessibility of mount points where your gluster volumes reside.
