from a mailing list:
Assuming you have data on sda1 and wish to mirror to sdb1, here are the steps I have used in the past:
- step one, make sure you have a full backup of your data on external device
- create a degraded RAID1 (single device using sdb1)
- mirror your data manually (I use tar) from sda1 to your raid device (md0 perhaps?)
- mount the raid device, reboot, etc ... whatever you wish to be confident that your copy is intact (perhaps diff -rq)
- once you're confident that your one-legged raid is good to go bring sda1 into the fold (used to be raidhotadd, these days it's "mdadm --manage ???")
It would be good (perhaps essential?) to set the partition types on both partitions to raid autodetect.
