IDE Raid5 in Debian Sarge
Hi
I'm having trouble building one of my RAID arrays.
Distro: Debian Sarge
Kernel: 2.4.27-1-386
During install I created /dev/md[02] from 2 SCSI HD's in RAID1 (swap, / & /home) and tried to create /dev/md3 from 4 IDE HD's on 2 onboard UDMA controllers in a RAID5 (all partitions ReiserFS).
The installation prg. didn't output any errors.
After installing and rebooting, the first 3 md devices work fine, but the system won't mount the /dev/md3 (the RAID5).
dmesg |grep hd:
SCSI device sda: 17783249 512-byte hdwr sectors (9105 MB)
SCSI device sdb: 17783249 512-byte hdwr sectors (9105 MB)
ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:DMA
ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:DMA
ide2: BM-DMA at 0xec00-0xec07, BIOS settings: hde:DMA, hdf:DMA
ide3: BM-DMA at 0xec08-0xec0f, BIOS settings: hdg:DMA, hdh:DMA
Why are the HD's listed as being scsi devices ?
Furthermore.. When first booting the system I discovered that the file /etc/raidtab hadn't been created so I did this manually, with info from the "Linux RAID Howto". But when typing:
mkraid /dev/md3
I get the response:
couldn't open device /dev/hda -- No such device or address
and the /proc/mdstat just shows my first 3 RAID1 devices (/dev/md[02])
How do I get my RAID5 up and running ?
(I admit - I'm somewhat of a linux n00b so break it to me gently ;)
