Hi all !
I'm having a problem configuring RAID1.
Installed sw at this point:
RedHat 6 (Hedwig); Kernel 2.2.12; raidtools-0.90-3.i386.rpm
Relevent Hw description:
3 SCSI disks: onde with 1G and the others with 2G.
/dev/sda (...) with the system
And, I have created in the other 2 hard disks only one partition with 2G
each: /dev/sdb1 and /dev/sdc1
However ,and I'm refering this 'cause it can be important and maybe the
reason for the problem, the sdb1 has cylinders of 4154*512 bytes and the sdc1
has cylinders of 4030*512 bytes .
Prob:
The famous: mkraid: aborted
The steps I walked through:
1. I've created the partitions sdb1 and sdc1 like described above.
2. The contents of the /etc/raidtab file:
# RAID1 configuration file
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
chunk-size 4
persistent-superblock 1
device /dev/sdb1
raid-disk 0
device /dev/sdc1
raid-disk 1
3. mkraid /dev/md0
handling MD device /dev/md0
analyzing super-block
disk 0: /dev/sdb1, 2095662kB, raid superblock at 2095552kB
disk 1: /dev/sdc1, 2033104kB, raid superblock at 2033024kB
mkraid: aborted
^^^^^^^^^^^^^^^^^
Well... anyway... I read a few messages posted to this mailling list and there
were some people that had a similar problem and I tried to go the other way
around:
3. mdcreate -c4k raid1 /dev/md0 /dev/sdb1 /dev/sdc1
and the contents of the /etc/mdtab was create like this:
# mdtab entry for /dev/md0
/dev/md0 raid1,4k,0,37ca643f /dev/sdb1 /dev/sdc1
4. mdadd /dev/md0 /dev/sdb1 /dev/sdc1
REGISTER_DEV sdb1 to md0 done
REGISTER_DEV sdc1 to md0 done
4. mdrun -p1 /dev/md0 OR mdrun -ar
/dev/md0: Invalid argument
I hope someone can help me with this :/
Thanks in advance for any suggestion, tip or "recipe" ;-)
