the first time i tried to install centos on my fileserver it detected my reiserfs drives but then didnt give me a kernel to actually access them - strike one
now im trying centos on my mail server, wipe the drives, created a mirrored raid array from the setup, (took over 14 hours to format and sync) finally finished the install AND IT DIDNT WRITE THE BOOT RECORD! when it rebooted i got my grub menu from GENTOO! - strike two,
now im back into the install cd, trying to figure out how to install grub like the install should have done for me, but there is no grub command at the prompt (trying to use tab completion) im ready to hurt something im so frustrated, can anyone help me out here? ive seen http://www.dur.ac.uk/a.d.stribblehill/mirrored_grub.html but without the grub command that page is useless. Im sure someone has to be booting RH/CentOS off mirrored software raid, some help please! id like to get this thing going tonight if possible, thanks!

Err, investigating whether upstream supports reiser would have been a good first move.

That's *extraordinarily* slow, as in something seems very bad.

I've had occasional problems with grub not getting properly installed. It's easy to fix. Put in the first CD, and boot with 'linux rescue'. Once it's mounted your install, 'chroot /mnt/sysimage' and 'grub-install /dev/sda' and/or just follow those instructions you mentioned.

Yeah, never thought i had to, every other distro ive tired has it, and it manages small files better than ext3, but i know now.

the drives are in perfect condition, ran the previous OS without any problems, they are almost new.

Every other non-enterprise distro, you mean ? Or have you tried the enterprise ones too ?
It is something many people keep forgeting. CentOS (and upstream) is not a standard distro, but an enterprise one. Rules change a lot in that case.

Maybe something related to the chipset ?

Note that Centos has an optional 'unsupported' kernel in the centosplus repository. If you want to add or mount existing reiserfs filesystems after installing you can install the kernel and utilities with yum.

I have grub booting off /dev/md0 right now which is mounted as /boot. And have with gentoo and many other distros, I think you have been mis-informed.

If it is a RAID1, I suspect that you are really booting from the underlying normal partition as far as grub is concerned and some magic in the installer figured out how to set it up for you. Lilo has had that magic built in for some time now but if Centos does it for grub it is a very recent addition. Normally you have to run grub manually to install it on both of the mirrored drives.

I think the grub install has been automagic since 4.0 came out. Before that I always kept a boot floppy halfway in the drive just in case the first drive failed.

Well, shouldn't the setup program not bark about this? I installed CentOS yesterday on a system that had been running reiserfs as well. The partition helper (disk druid or what it is) showed it and didn't indicate I should not setup on it. Luckily, I wanted to wipe and format with ext3, anyway. F.i. if you choose a /boot partition lower than 75 MB (I used 50 MB) setup will sound a warning.

I believe if you choose ext2 vs ext3, the size of 75mb will be fine. "ext3" needs some extra space for the journeling factor. For /boot one needs no journeling anyway, it's not a rw item, virtually a "read-only" partition.

I went along with 50 MB (and ext3) since I knew I'd never need that much, at the moment it's less than 10 MB. All is well.
