grub cannot find its second stage. Are you booting from a mirrored partition?
Yes
What could be a solution? And what could have happen upon the reboot?
That is weird. I just re-installed centos5 and it is now booting properly. What could I do to avoid this situation in the future?
IIRC, RHEL4 does not properly handle installation of grub on mirrored partitions and therefore Centos4 suffers from the same problem.
RHEL5 does it properly now as you can see. This has been a long outstanding problem of anaconda.
Yeap, this is true. After installing centos4 on RAID1 disk (software raid) i always do:
grub grub>device (hd0) /dev/hdc grub>root (hd0,0) grub>setup (hd0)
where /dev/hdc is second RAID DISK (it could be whatever: /dev/sdb1 etc)
Ok, on one system I had /boot as /dev/md0, and md0 is composed of /dev/hda1 and /dev/hdb1.
I have done:
grub> device (hd0) /dev/hdb
grub> root (hd0,0) Filesystem type is ext2fs, partition type 0xfd
grub> setup (hd0) Checking if "/boot/grub/stage1" exists... no Checking if "/grub/stage1" exists... yes Checking if "/grub/stage2" exists... yes Checking if "/grub/e2fs_stage1_5" exists... yes Running "embed /grub/e2fs_stage1_5 (hd0)"... 16 sectors are embedded. succeeded Running "install /grub/stage1 (hd0) (hd0)1+16 p (hd0,0)/grub/stage2 /grub/grub .conf"... succeeded Done.
Am I in the right way?
Thanks,
