acebmxer said: I have issue with rolling pool update with 1 of my 3 pools at work. It was the last pool to be updated. Host 1 updated no issues. vms stopped migrated off host 2 to complete updates. Support ticket opened - Ticket#7758427. Found 1 vm with cpu stuck at 100% and unresponsive. Force rebooted vm and proceed updates on host2. Well I think i found the source of my problems. After having continues other odd issues with this remote pool. I decided i was going to reboot everything. That's when every vm started to fail. Logged into Synology rs1221+ and it was just very sluggish and not responsive. No new error alerts or anything to explain the odd behavior. Rebooted it and even after boot still odd behavior until finally disk error. Then the system started to respond. Luckily I have a spare drive onsite but cant gain access until Monday possibly Tuesday. Fingers crossed. Lucky for backups. Looks like the important vms had a successful backup as of yesterday so thats good.
