hello,
i have a disk with data on it /dev/hdc,
and a brand new empty disk /dev/hdb.
want to set up raid 1 without moving data off hdc.
it very large and i have no where to put it
will this work?: (notice # of devices)
mdadm --create --verbose /dev/md0 --level=1
--raid-devices=1 /dev/hdb
will this create an unmirrored raid 1 setup?
can i start and mount md0?
then copy the data from hdb to md0?
then?:
mdadm /dev/md0 --add /dev/hdc
seems too good to be true,
maybe you know another way?
jd
