[CentOS] MD Raid 1 software device not booting not even reaching grub
Hi, I have a raid 1 setup where /boot and the rest lies inside the md0 container. /dev/sda1 md0 has /boot /dev/sda2 md0 has swap /dev/sda3 md0 has / SCSI card is an ADAPTEC AIC79xx Grub as the bootloader Centos 4.1 as the OS version Two 70gb SCSI disks The server was working fine. Then a power outage. checked the board,disk,ram,etc. All fine. Now when I try to boot the server does not even reach GRUB (no splash, no menu). I read a post about maybe the MBR got damaged (no fix posted) and another post about missing SCSI drivers not being loaded before kernel boot. Suggestions? -- ------------------------------------------- Erick Perez Linux User 376588 http://counter.li.org/ (Get counted!!!) Panama, Republic of Panama

[CentOS] Re: MD Raid 1 software device not booting not even reaching grub
Forgot to mention that if I use the rescue mode CD, partitions are being recognized and I can do a "chroot /mnt/sysimage". However, no idea where to go from there.
