Replacing fail boot disk from md raid1 set One of my disk fail and I replace it with new one. I fail to make the new disk bootable. Right now the system is boot only from IDE2 master (hdc1) Here are the steps I made, it use to work on previous occurrence: - fdisk the new disk -Adding all the partition to the raid array /sbin/raidhotadd /dev/mdX /dev/hdaY... - Reboot from a Linux CD-ROM in rescue mode. - mkdir /mnt/hda_disk_par1 - Mount the / partition mount /dev/hda1 /mnt/hda_disk_par1 - Replace md1 with hda1 in /etc/lilo.conf - chroot /mnt/hda_disk_par1 /sbin/lilo - Replace hda1 with md1 in /etc/lilo.conf - halt - disconnect hdc - boot At this stage the system not boot. I can boot it only in one of those senarios: From boot diskette or connecting again hdc. After boot the raid status of all the partition is [UU] (up) The configuration: -Red Hat 8.0 -Two IDE disk both master on IDE1 (hda) and IDE2 (hdc) -My bios is capable to boot from IDE1 or IDE2 master -lilo boot loader -My bios is capable to boot from IDE1 or IDE2 master Any Idea what wrong?
