@Denson After enabling HA, the host has to be manually rebooted, which I think you're already aware of. OK, well, that leaves pretty much a network issue. Hmm. The statefile created OK on the shared SR within the pool? The "not found" error message doesn't give you much to go on, unfortunately.

Then I would try again after installing all updates.

Ah great news then!

@olivierlambert Those were the only messages on the log, nothing else captured on any other log file like the crit.log file or dmesg
