Hi,
I am trying to configure an array of 12 disks in a RAID 10
configuration. All 12 disks are identical 146Gb drives.
First off, on each disk I created a single partition which spanned the
whole disk with a system id of 0xFD. After writing the partition
table, a print confirmed all looked good.
Secondly, I used mdadm to create 6 RAID 1 pairs. (mirrored).
mdadm --create /dev/md0 --level=1 -n 2 /dev/sda /dev/sdb
mdadm --create /dev/md1 --level=1 -n 2 /dev/sdc /dev/sdd
mdadm --create /dev/md2 --level=1 -n 2 /dev/sde /dev/sdf
mdadm --create /dev/md3 --level=1 -n 2 /dev/sdg /dev/sdh
mdadm --create /dev/md4 --level=1 -n 2 /dev/sdi /dev/sdj
mdadm --create /dev/md5 --level=1 -n 2 /dev/sdk /dev/sdl
I think that maybe you wanted to use /dev/sda1 and /dev/sdb1
instead of /dev/sda and /dev/sdb
The disks need partition tables.
