Well it obviously sucks to have to re-install OMV after a hard drive failure, specially when the SSD is brand new
But overall that was a very painless process thanks to the wonders of Docker.
I made sure i had copies of all my stacks, so once i restored my AppData share everything was up and running in no time
If i had to redo all that on a windows pc it would have taken me over a day to get all my settings back for Home assistant, Emby, Sonarr, Radarr, ....
Still lots to learn, but i'm liking it!
