Dear All,
I have recently had a bad experiences with Centos 4.0 and 4.1 when
installing onto mirrored IDE drives using software mirror.
The install goes through ok, but when the system comes to reboot, it
seems the boot loader fails. I've seen fail on the first reboot or
after a random number of reboots, across different hardware as wide and
varied as you can get, the common factor is software raid, (mirrored
drives).
It either fails just displaying "GRUB" or fails with a flashing cursor
at the bootup time.
Booting a rescue cd, doing a chroot /mnt/sysimage and then the following
grub commands fixes the issue permanently, so that it never fails again,
grub
grub-> root (hd0,0)
grub-> setup (hd0)
grup-> root (hd1,0)
grub-> setup (hd1)
grub-> quit
it seems to me the Anaconda installer doesn't do something quite right
which leads to this random style failure. Its only random as to when it
will do it, unless you do this, it will do it at some point.....
I've been doing Redhat for many years and never seen this problem
before......anybody else seen this
P.
