Quick simple post…

After trying to upgrade from 4.7.1 to 4.8 I ran into a failure and was getting the error: Failed to create cluster snapshot

I checked free space on all nodes and everything was fine… After looking through the logs and finding nothing useful…. I was left scratching my head… Anyway long story short it was NTP!!!

1 of the nodes in the cluster was out by about 20 seconds!! which was enough for the upgrade to fail.

NTP strikes again!!

Hope this was helpful
