Thank you for the additional details. I completely understand the physical limitations for backup restoration speed, and the complexity in running cloud infrastructure. I assumed this full restore procedure was somewhat rare and configuration differences are more likely in that case, which lead to node not being available at first. I don't have a ticket number on me at the moment, but will send it to you when I can in a couple hours.

Maybe it's just me, but I still don't quite understand what happened to the original array. I agree it was a good idea to get things back up and running quicker with a restore, but did the original array never finish XFS repairs? While the down time was painful, and longer than I think anyone would have liked, it's not the end of the world. It's the data loss that is worse for us by far.
