Hi All,
I'm having trouble mouting my root file system as part of a software
RAID-1. First my setup.
OS: Debian Woody with kernel 2.4.20-XFS (all required fs and RAID
support compiled in, not as modules)
HDDS: Two 40GB drives connected to a Promise PDC 20276 (recognised by
the system as two seperate drives hde and hdg), 1 80GB drive
connected as secondary slave (hdd).
Originally I installed the OS onto hdd, when I boot off it, the system
looks like this:
--
jupter:~# cat /etc/mtab
/dev/hdd2 / ext2 rw,errors=remount-ro 0 0
proc /proc proc rw 0 0
devpts /dev/pts devpts rw,gid=5,mode=620 0 0
/dev/md2 /mnt/new-root ext3 rw 0 0
/dev/md1 /mnt/new-root/boot ext3 rw 0 0
/dev/md5 /mnt/new-root/home xfs rw 0 0
/dev/md6 /mnt/new-root/tmp xfs rw 0 0
/dev/md7 /mnt/new-root/usr xfs rw 0 0
/dev/md8 /mnt/new-root/var xfs rw 0 0
--
The software RAID is working, the md devices will sync and mount and I
have created the file systems on them and copied the whole OS over to
the RAID partitions.
I added the following lines to /mnt/new-root/etc/lilo.conf:
--
boot=/dev/md1
raid-extra-boot="/dev/hde, /hdev/hdg"
root=/dev/md2
--
And run the following command:
--
jupiter:~# chroot /mnt/new-root/ /sbin/lilo
Warning: using BIOS device code 0x80 for RAID boot blocks
Added Linux *
Added LinuxOLD
The boot record of /dev/md1 has been updated.
The boot record of /dev/hde has been updated.
The boot record of /dev/hdg has been updated.
--
Which all looks good... but when I reboot, I get this:
--
NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.
EXT3-fs: unable to read superblock
EXT2-fs: unable to read superblock
iofs_read_super: bread failed, dev=09:01, iso_blknum=16, block=32
XFS: bad magic number
XFS: SB validate failed
Kernel panic: VFS: Unable to mount root fs on 09:01
--
When trying to mount the root file system.
I don't get it. I can mount the RAID partitions under /mnt no problems,
I can boot off the RAID device /dev/md1, I just can't mount /dev/md2 as
my root file system. Can anyone shed some light on this for me? What
do I need to do? I have experimented with the LiLo setup and found that
the system will boot up as expected with /dev/hde2 (or /dev/hdg2) as the
root file system... why doesn't it like /dev/md2? Thanks in advance.
Regards,
Lucas
