Sure not a problem. For the first issue regarding agent and broker crashing. Again the hosted engine VM is up and running at this time, I have no idea why the logs are saying volume doesn't exist and why file /var/run/vdsm/storage/248f46f0-d793-4581-9810-c9d965e2f286/14a20941-1b84-4b82-be8f-ace38d7c037a/8582bdfc-ef54-47af-9f1e-f5b7ec1f1cf8 does not exist when the file actually does exist in that path.
Perhaps not enough permissions?
Can you try reading it as user 'vdsm'? E.g.
su - vdsm
su - vdsm -s /bin/bash
cp /var/run/vdsm/storage/248f46f0-d793-4581-9810-c9d965e2f286/14a20941-1b84-4b82-be8f-ace38d7c037a/8582bdfc-ef54-47af-9f1e-f5b7ec1f1cf8 /dev/null
I assume this problem is most likely also related or causing my other problems when accessing hosted vm snapshot section of web gui as well.

First, apologies for all the posts to this list lately, I've been having a heck of a time after 4.2 upgrade and you've been helpful, I appreciate that.
Since 4.2 upgrade I'm experiencing a few problems that I'm trying to debug.
Current status is engine and all hosts are upgraded to 4.2, and cluster and domain set to 4.2 compatibility. Hosted Engine VM is running and ui accessible etc, all VMs on hosts are running but no HA service. Web UI is giving a few errors when checking network and snapshots on the hosted engine VM only, it doesn't give errors on any of the others VMs that I spot checked.
1. HA-agent and HA-broker are continually crashing on all three hosts over and over every few seconds. I sent an email to users list with more details on this problem but unfortunately haven't heard anything back yet. The general error in the logs seems to be: VolumeDoesNotExist(leafUUID)#012VolumeDoesNotExist: Volume does not exist: (u'8582bdfc-ef54-47af-9f1e-f5b7ec1f1cf8',) -- What? Volume doesn't exist, why not?
If agent/broker logs do not reveal this, the next step is usually checking vdsm logs and/or system logs. Can you please check/share these? Thanks.
2. Error when clicking "network interfaces" in the web gui for the hosted VM engine.
3. Similar to #2 above an error is given when clicking "snapshots" in the web gui for the hosted engine VM.
The errors for #2 and #3 are generic "cannot read property 'a' of null". I've read previous postings on ovirt-mailing list that suggest you can install debug-info package to get a human readable error.. but this package does not seem to be compatible with 4.2, it expects 4.1: Requires: "ovirt-engine-webadmin-portal = 4.1.2.2-1.el7.centos" -- Perhaps this package is no longer required? I do see some additional details in the ui.log that I can post if helpful.
There is obviously something odd going on here with the hosted engine VM. All three errors appear to related to a problem with it, although it is indeed up and running. I'd really like to get HA broker and agent back up and running, and fix these GUI errors related to hosted engine VM. All three problems may be connected to one common issue?
Thanks in advance!
