Hello, Sorry if this has been answered before, but I'm having trouble finding the relevant messages by searching. Several solutions are floating around. Want to configure a simple no-bitmap RAID1 with three-drives, one always stored off-site. Will rotate only two or three times a year so I'd rather have the no-bitmap setup where the incoming drive gets a full resync--takes just eight hours. Have a daily incremental cloud-backup, which allows infrequent visits to the safe-deposit box. What are the correct approach and commands for this? Will never have three drives together on-site. I'm nervous about using --fail --remove to take the mirror copy offline, fearing that it could put the backup in an unusable state. Thinking a --stop might be cleanest approach. Wondering if --grow --raid-devices=1 --force after the drive is removed and then --grow --add --raid-devices=2 with the returning drive is correct or if a --raid-devices=3 with no --grow on rotation is better. I'm looking for the most correct way to go, but don't have enough experience of 'mdadm' to have a sense of what it should be.
