Hi folks. I'm having a bit of trouble, and was wondering if I could get
some help.
---------The Short Version
I'm getting:
# raidstart /dev/md0
/dev/md0: Invalid argument
The RAID stuff is compiled into the kernel, not as modules. /proc/mdstat
shows all inactive, but mkraid will not work for me:
# mkraid /dev/md0
handling MD device /dev/md0
analyzing super-block
disk 0: /dev/sdb1, 4257193kB, raid superblock at 4257088kB
disk 1: /dev/sdc1, 4257193kB, raid superblock at 4257088kB
disk 2: /dev/sdd1, 4192933kB, raid superblock at 4192832kB
mkraid: aborted
---------The Gory Details
I've read all the documentation I can find (I joined this list a week ago
to ask this question, but decided to search around and see if the answer
was already posted/documented...)
I'm running a 2.2.3 kernel that I compiled with RAID turned on. Two of
these drives are on an Adapted 7880, one is on the 2940A (as is my boot
disk, /dev/sda). They all format and run normal partitions just fine, but
I just can't get them to work together.
# cat /proc/mdstat
Personalities : [1 linear] [2 raid0] [3 raid1] [4 raid5]
read_ahead not set
md0 : inactive
md1 : inactive
md2 : inactive
md3 : inactive
# cat /etc/raidtab
raiddev /dev/md0
raid-level linear
nr-raid-disks 3
persistent-superblock 1
device /dev/sdb1
raid-disk 0
device /dev/sdc1
raid-disk 1
device /dev/sdd1
raid-disk 2
# cat /etc/mdtab

# mkraid --really-force /dev/md0

Any help would be appreciated!
Thanks!
