Hi
I have a 9-drive ZFS2-pool (4TB WD Red), anre are planning on upgrading to 9x10TB drives. Everything on my NAS is backed up in the cloud!
What would be the best way to upgrade? I dont have enough extra space to temporary store everything currently on the server locally (approx 20TB).
One option is to replace one (or two) drives at a time. I know I will increase the risk of losing the entire pool if the resilvering process fails while I replace two drives at a time, but this will cut my resilver-time in half (I hope). Would you resilver one drive at a time, or two?
Keep in mind, I have everything backed up. The only consequence of a failure, is having to download everything from my online backup, which would take at least about a week, but I would imagine resilvering 9 times will take significantly longer than this.
