Sorry if this comes twice, but netscape crashed right when I hit the send button, so not sure if the first one made it. Hello, Looking for some help/advice. I'm trying to append three logical drives defined on a HP NetRAID 3si Raid controller. The sizes of the three logical drives are :363Gb, 101Gb and 34Gb. I have read through the Software-RAID.HOWTO.txt doc and have setup the kernel and raidtab file as specified in the doc (I'm running RH6.2) plus set the fd for the partition types. Anyway when I run the mkraid command this is what I get: [root@megatera /etc]# mkraid /dev/md0 handling MD device /dev/md0 analyzing super-block disk 0: /dev/sdc1, 373414828kB, raid superblock at 373414720kB disk 1: /dev/sdd1, 106687633kB, raid superblock at 106687552kB disk 2: /dev/sde1, 35559846kB, raid superblock at 35559744kB /dev/md0: Invalid argument Here is what the /proc/mdstat file says: [root@megatera raidtools-0.90]# more /proc/mdstat Personalities : [linear] read_ahead not set unused devices: <none> Have I hit a size limit on what the raidtools/kernel can handle?
