I am trying to implement mirroring RAID-2 for Redhat 6.0 ecommerce
version. Kernel version is 2.2.5-15Smp (I have a dual celeron 366
ABIT Motherboard).
I have connected the two SCSI HDs 4.4G (IBM DDRS)on a Adaptec
2940 UW controller card (SCSI ID 6 & 10).
I partitioned the HDs as sda1 => /home1 , sdb1 => /home2 .
I want to mirror /home1 and /home2 .
I added the following lines in /etc/conf.modules
alias md-personality-3 raid1
alias md-personality-4 raid5
I have looked through the HOW-TOs
http://www.linuxgazette.com/issue45/nielsen.html
and created /etc/raidtab
as follows
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
chunk-size 4
persistent-superblock 1
device /dev/sda1
raid-disk 0
device /dev/sdb1
raid-disk 1
I then typed mkraid /dev/md0 it came up with the following
handling MD device /dev/md0
analyzing super-block
disk 0: /dev/sda1, 4458006kB, raid superblock at 4457920kB
/dev/sda1 is mounted
mkraid: aborted
Can somebody point me further from here ?? I am looking at the
HOW-TOs and other web based doc.
Thanks,
