friends, first of all thanks for all the responses I get from u all to help me out in past, and sorry for this question being a little long. Because the conf. files are small I am posting them otherwise i would have put them on my yahoo briefcase.
:-( These days I am fiddling with software Raid level 5 with / as well as /boot partition on RAID device with lilo-21.4.4-14 using raidtools-0.90-23 on RH7.2 with a system of 3 SCSI Hard disks on intel L440GX smp motherboard. there are two raid devices I am configuring, md0 (RAID5)and md1(RAID1 ) for / and /boot respectively as I wanted the system to boot on RAID and probably lilo can understand RAID1 but not RAID5 My procedure is as follows: a) creating the raid devics as per the conf file below , with 3 partitions sda1,sdb1,sdc1 with initial full installation on sda1 and that is why initially sda1 is made failed-disk to remove it from the raid because it already contains / filesystem and also because I have only 3 hard disks.Once raid works I will include sda1 in it to bring redundancy in my RAID5 for / b) created filesystems ext2 and reiserfs respectively on md1 and md0 respectively, copied all files in / directories on md0 and /boot dir on md1 ( This step is also perfect i am pretty sure). c) edited my /etc/fstab (shown below) d) ran lilo -v after editing lilo.conf with a floppy in drive, lilo was written. When I try to boot the system on RAID with the floppy to test it before installing lilo on hard disks, I get an error as follows(which occurs after my hard disks partitions are detected: -------------------------- loading jbd module loading ext3 module mounting /proc filesystem Creating root device Mounting root filesystem EXT3-fs: unable to read superblock mount: error 22 mounting ext3 pivotroot: pivot_root (sysroot, /sysroot/initrd) failed: 2 freeing unused kernel memory: 240k freed kernel panic: No init found. Try passing init=option to kernel. -------------------------- MY QUESTION IS THAT WHEN I AM NOT MOUNTING ANY EXT3 FS, WHY IS THE KERNEL GIVING EXT3-fs ERROR. ( MIGHT BE IT SEES REISERFS AS EXT3 fs), WHY IS MY SYSTEM NOT BOOTING ON RAID. ANY OTHER PARAMETER TO BE PASSED TO LILO.CONF? ( to tell u all of my raid partitons are set to tpye "fd" using fdisk so that kernel autodetects them) -------------------------- My /etc/raidtab: ---------------------- raiddev /dev/md0 raid-level 5 nr-raid-disks 3 nr-spare-disks 0 persistent-superblock 1 parity-algorithm left-symmetric chunk-size 32 device /dev/sdb1 raid-disk 1 device /dev/sdc1 raid-disk 2 device /dev/sda1 failed-disk 0 raiddev /dev/md1 raid-level 1 nr-raid-disks 3 nr-spare-disks 0 persistent-superblock 1 chunk-size 32 device /dev/sda3 raid-disk 0 device /dev/sdb3 raid-disk 1 --------------------------- --------------------------- my lilo.conf for floppy booting (to test before installing lilo on harddisks): --------------------------- boot=/dev/fd0 install=/boot/boot.b message=/boot/message map=/boot/map lba32 prompt delay=50 timeout=50 default=linux-raid image=/boot/vmlinuz-2.4.7-10smp label=linux-raid #initrd=/boot/initrd-2.4.7-10smp.img root=/dev/md0 read-only ---------------------------------- ---------------------------------- My /etc/fstab: --------------------------------- /dev/md0 / reiserfs defaults 1 1 /dev/md1 /boot ext2 defaults 1 1 none /dev/pts devpts gid=5,mode=620 0 0 none /proc proc defaults 0 0 none /dev/shm tmpfs defaults 0 0 /dev/sdb2 swap swap defaults 0 0 /dev/sdc2 swap swap defaults 0 0 /dev/sda2 swap swap defaults 0 0 /dev/cdrom /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0 /dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0 ======================= Thanks for going through my idiotic mail Regards, Sagar Srivastava CWLGobal,Bangalore _______________________________________________ linux-india-help mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/linux-india-help
