Subject: split raid1 into to arrays
Date: Tue, 27 Mar 2007 04:54:47 +0200 [thread overview]
Message-ID: <5d0f60990703261954l2bb8c225ocbc3cf66e868723a@mail.gmail.com> (raw)
Hello experts,
I have a raid1 array with two drives working. It /dev/md0 built from
/dev/hda and /dev/hdb. Now I'd like to split it into two array with
one drive each (and then later add spares to my two arrays again). I
know that I can remove one drive from the array with: mdadm /dev/md0
-f /dev/hdb -r /dev/hdb , however I'm not sure what the superblock of
/dev/hdb now contains and how I could use the contents of /dev/hdb as
the starting point for my new /dev/md1 array? I did not find anything
in the manpage of mdadm which would provide me an automatic split.
So what are your advises?
