Subject: Upgrading Raid1 array to have 2. disks.
Date: Wed, 07 May 2003 01:24:15 +0200 [thread overview]
Message-ID: <3EB8441F.8070606@fugmann.dhs.org> (raw)
Hi,
Sorry if this is the wrong list to post this on.
I have made an error when creating a new raid1 array as I specified that
the raid should consist of only one disk. Now, I would like to add
another disk, but mdadm insists on adding it as a spare disk, offering
no data redundancy.
Before:
md0 : active raid1 ide/host0/bus0/target0/lun0/part1[0]
1048704 blocks [1/1] [U]
After running
# mdadm -add /dev/md/0
/dev/ide/host0/bus0/target0/lun0/part1[0]
md0 : active raid1 ide/host0/bus1/target0/lun0/part1[1]
ide/host0/bus0/target0/lun0/part1[0]
1048704 blocks [1/1] [U]
I have read the manpages, and tried googling without success.
I do not wish to destroy the data on the discs, and recreate the array
but It might be a last resort. Can anyone help me convince mdadm to add
the 2. partition as an active disk.
Regards
Anders Fugmann
P.s.
