Hi -
I'm having
difficulty getting software RAID0 to work on the following
configuration:
/dev/hda - / partition, contains all
boot, system files.
/dev/hdb - disk 1 of
RAID0
/dev/hdc - hardlinked to
/dev/cdrom
/dev/hdd - disk 2 of
RAID0
Both drives are
Western Digital 18gb Ultra/66 drives (AC418000). Kernel version is
2.2.9-19mdk (Mandrake 6.0 recompiled with RAID0 support built in, not
modular).
My /etc/raidtab file
looks like this:
--------------------------------
raiddev
/dev/md0
raid-level 0
#
persistent-superblock 1
chunk-size 32
#
nr-raid-disks 2
nr-spare-disks 0
#
device /dev/hdb1
raid-disk 0
#
device /dev/hdd1
raid-disk 1
--------------------------------
raid-level 0
#
persistent-superblock 1
chunk-size 32
#
nr-raid-disks 2
nr-spare-disks 0
#
device /dev/hdb1
raid-disk 0
#
device /dev/hdd1
raid-disk 1
--------------------------------
mkraid 0.90.0 returns the
following:

mkraid: aborted, see the syslog and /proc/mdstat for potential clues.

/proc/mdstat looks like
this:

md2 : inactive
md3 : inactive

md3 : inactive

syslog doesn't
contain any information that I recognize as pertinent, with the exception of the
message that indicated that the RAID0 personality was loaded at
boot...
I've looked at all
the docs on this that I can find, which appear to be out of date, and refer
to tools that don't exist in the newer raidtools packages. I've created
the /dev/hdb1 and /dev/hdd1 partitions both as type 83 (ext2) and fd (so
that they automount), but I can't get the RAID to start with either type, and
it's driving me nuts. Are the 18gb drives too big for software RAID?
Can anyone give me a clue as to what the heck is wrong here?
Thanks!
Rob
