Any time you see a /proc/mdstat listing md0 through md3 with all of them inactive,
it means that the kernel has NOT been patched with the latest raid code. Even the
latest 2.2.XX kernels need to be patched up to the raid 0.90 version.
The patch for the 2.2.14 kernel can be found at http://www.redhat.com/~mingo
Patches for earlier 2.2 kernels can be found at ftp://ftp.us.kernel.org in the deamons/raid/alpha directory, I forget the full path.

Hi ,
I have linux 2.2.13 (SuSE) and a problem with a raid1.
I included 2 new SCSI-HD, in my system, created 3 Partitions sda1..3,
sdb1..3 (3x3GB), and i will use only a part of this, so I created
/etc/raidtab
----------------
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
persistent-superblock 1
chunk-size 4
device /dev/sda1
raid-disk 0
device /dev/sdb1
raid-disk 1
# mkraid /dev/md0
----------------------------
handling MD device /dev/md0
analyzing super-block
disk 0: /dev/sda1, 3084448kB, raid superblock at 3084352kB
/dev/sda1 appears to contain an ext2 filesystem -- use -f to override
mkraid: aborted, see the syslog and /proc/mdstat for potential clues.
so what i do is
---------------------
# mkraid --really-force /dev/md0
----------------------------------------------
DESTROYING the contents of /dev/md0 in 5 seconds, Ctrl-C if unsure!
handling MD device /dev/md0
analyzing super-block
disk 0: /dev/sda1, 3084448kB, raid superblock at 3084352kB
disk 1: /dev/sdb1, 3084448kB, raid superblock at 3084352kB
mkraid: aborted, see the syslog and /proc/mdstat for potential clues.
I can't find any wrong messages in /var/log/messages

Do you have a idea what is wrong ???
