      On Sunday I did pool updates for the latest patches and everything seemed to go fine for the most part. However, the last two nights I have had hosts suddenly decide they needed to be fenced and reboot. On Monday morning it was 2 of them, and then this morning 4 of them that rebooted (it's a 5 node pool).

      Did any of the most recent updates make HA a bit more punchy or is that coincidental?

      Interpreting the xha log is pretty rough for me at this point so I'm having a trouble determining the exact source of the problem - it certainly seems to be a state file disagreement. I'm thinking maybe the backups task, which kicks off at midnight, is having a negative impact to the storage performance enough to cause this - but that's only a guess.

      Any insight would be appreciated! 😊

        Hi,

        I would disable HA for a bit and keep an eye on the shared storage connectivity for a bit (eg a simple dmesg in the Dom0 can display very interesting info). This will reduce the potential disruption until you find the root cause. I'm not aware of any change in XHA recently (pinging @ronan-a in case)

          @jasonmap No recent changes regarding the HA on our repositories. So it can be a connection issue. Like said by Olivier, you can have more info using dmesg. Or even daemon.log/SMlog (it will depend on the shared SR used).

            Right, so yeah I did just that - disabled HA and have been keeping an eye on the logs as well as general performance in the env. Glad to know my actions align with your recommendations at least 😆

            There are a couple of hosts that get a lot of these sorts of messages in the kern.log:

            Apr 25 08:15:33 oryx kernel: [276757.645457] vif vif-21-3 vif21.3: Guest Rx ready
Apr 25 08:15:54 oryx kernel: [276778.735509] vif vif-22-3 vif22.3: Guest Rx stalled

Apr 25 08:16:04 oryx kernel: [276788.780836] vif vif-22-3 vif22.3: Guest Rx ready

            Am I wrong to attribute this to issues within specific VMs (i.e. not a hv performance issue)?

            I know one of the VMs that causes these is a very old centos 5 testing VM one of my devs use and the messages stop when it's powered down.

            Is there any way to easily associate those vifs with the actual VMs they are attached to? My google-foo failed me for that.

            Other than that, I noticed my nic firmware is a bit old on the X710-da2's I use so I'm going through and upgrading those with no noticeable changes. I'm fairly hesitant to re-enable HA without tracking down the root cause.
