This is the first time I am setting up raid using the mdadm tool. This
is what I am trying to do.
The sever is as follows: 2 drives at 10gig
2 drives at 80gig
hda2 is /
hdd1 is my /home
I have the other drives in ad ready and would like to set up the 2 10
gig's as a mirror and the 2 80 gig as raid0
At the shell I run this command
mdadm --create /dev/md0 --level=1 --raid-disks=2 /dev/hda2 /dev/hdb1
and get the following output:
mdadm: /dev/hda2 appears to contain an ext2fs file system
size=7269412K mtime=Mon Jul 1 11:56:16 2002
mdadm: /dev/hdb1 appears to contain an ext2fs file system
size=7333640K mtime=Mon Jul 1 11:56:29 2002
Continue creating array? y
mdadm: SET_ARRAY_INFO failed for /dev/md0: File exists
Could someone please help me with this problem. I am having a really
hard time finding any info on the web about this.

hda2 is mounted as / and you are trying to make a raid1 array
containing it. This cannot work.
What you want to do is:
mdadm --create /dev/md0 --level=1 --raid-disks=2 missing /dev/hdb1
to create a degraded array containing just hdb1.
Then:
mkfs /dev/md0
mount /dev/md0 /mnt
cp -ax / /mnt
to copy your root filesystem onto /dev/md0.
Then tell lilo:
append= "root=/dev/md0 md=0,/dev/hdb1"
and tell fstab that root in on /md0, and reboot.
Then you should be be running with root on /dev/md0 which consists of
/dev/hdb1, and /dev/hda2 will be unused.
Then
mdadm --add /dev/md0 /dev/hda2
to add hda2 to the mirror. Wait for resync.
Change lilo.conf to say the right thinggs, run lilo and reboot.
Note: it appears that hdb1 is bigger than hda2. If this is so you
will need to give a --size= to mdadm when created md0 so that it is
small enough to be able to use hda2.
Subtract 128 K from the size of hda2, so
mdadm --create /dev/md0 --size=7269280 ......

Thanks so much. That fixed it. It is now up and running.

Hi,
I obtained this email address from Neil Brown's blog site as being the
address to email if we had any issues with mdadm or Linux software RAID in
general.
I have an issue with some RAID1 arrays I have set up on an Ubuntu (Gutsy
7.10, 2.6.22-14-server) installation where arrays seem to randomly become
degraded during the boot process. I have included some of the superblock
data captured before a shutdown, and after boot. Note that arrays 5-8 are
degraded after boot. It also happens with arrays 1-3 so it's not an
extended partition issue. Notice that the Events field for the arrays that
are degraded have a different value for both of the mirrors and even the
array itself.
Any suggestions you could offer would be greatly appreciated. I would
prefer to resolve this problem before deploying the server in a production
environment.
