Hi,
I have 2 identical xSeries 346 with 2 identical IBM 72GB scsi drive. What i did is install the centos 4.2 serverCD on the first IBM and set the HDD to raid1 and raid0 for swap. Now what i did is get the 2nd HDD in the 1st Server swap it with the 1st HDD in the 2nd Server and rebuild the Raids. The 1st server rebuild the array fine. My problem is the Second server, after rebuilding it and rebooted it, i need to rebuild the 2nd HDD again in the 2nd Server i don't know what went wrong.
Here's my dmesg in my 1st server specific in md:
md: raid0 personality registered as nr 2
md: raid1 personality registered as nr 3
