(source not recorded):
Assuming you have data on sda1
and wish to mirror to sdb1
, here are the steps I have used in the past:
- 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 (maybe with
tar
) fromsda1
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
(diff) ) -
Once you're confident that your one-legged raid is good to go bring
sda1
into the fold (used to beraidhotadd
, these days it'smdadm --manage ???
)
It would be good (perhaps essential?) to set the partition types on both partitions to raid autodetect.
