I am having trouble bringing up a raid 0 volume. I followed the instructions in Jakob
OEstergaard's document and read the man pages, but I am still getting problems. When
I run the mkraid I get the following output:
[root@ahab /etc]# /sbin/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/sdc1, 8883913kB, raid superblock at 8883840kB
disk 1: /dev/sdd1, 8883913kB, raid superblock at 8883840kB
disk 2: /dev/sde1, 8883913kB, raid superblock at 8883840kB

disk 4: /dev/sdb2, 8883913kB, raid superblock at 8883840kB
mkraid: aborted
Note that I had to use the --really-force option because I used the older raidtools
software to see if they worked. They did, but I didn't know how to take the
filesystem info off so I have to use this option.
Here is my /etc/raidtab file.
raiddev /dev/md0
raid-level 0
nr-raid-disks 5
persistent-superblock 1
chunk-size 1024
device /dev/sdc1
raid-disk 0
device /dev/sdd1
raid-disk 1
device /dev/sde1
raid-disk 2
device /dev/sdf1
raid-disk 3
device /dev/sdb2
raid-disk 4
Note that I have tried several variations on this file including knocking the chunk
size down to 4 and including the nr-spare-disks option.
Any help would be greatly appreciated.
Thanks,
Rob Jones
