You wanna know how to migrate single disk --> raid1?
i know one recomended method (by Martin Bene):
1) mkraid with the disk containing your data specified as
"failed-disk" instead of "raid-disk". This creates the raid array in
degraded mode, using just the new disk.
2) create a new filesystem on the raid device (mke2fs)
3) copy data from old filesystem to new filesystem on raid (cp -a
generaly works ok).
4) restart system using just the new raid device
5) if all is well, raidhotadd the old disk to the raid device to make
it redundant.
More detailed explanations can be foind on the list archives by
searching for "failed-disk", has been discussed quite often.
Thanks,
Edward.
