This applies if it's a RAID 1 install and not a RAID 0 install (Can you do a RAID 0
with esmith?)
Last time I tried the RADI 1 install, it put both parts of the raid on the same
physical drive
i.e. /dev/md0 was formed from /dev/hda1 and /dev/hda2. Never even used /dev/hdb
This may account for your 4G drive showing a 2G /dev/md0 partition.
I think it's a bug with the disk druid which is used with the kickstart installation.
To double check, look at the /etc/raidtab file and see what real devices (/dev/hda1,
/dev/hda2, ..)
make up the RAID device (/dev/md0).
Personally, I've given up with the RAID 1 on e-smith/Red Hat with the kickstart
installation.
An it is almost impossible to manaually build the root RAID installation. I did one,
it's not fun.
For now , I just spent the $130 for a 3ware card. I'll post how it goes later?
Install e-smith tonight :-)
p.s
If you want to try to fix the booting, just rerun lilo as root.
That will read the /boot/lilo.conf file and rewrite the MBR.
If the boot fails after displaying "LI", you may need to put the "linear" keyword in
the
lilo.conf file. Search google on LILO and linear for exact placement.
Hope this helps.

Gotta love those boot floppies! :-)

Just to be sure we are clear... we're talking about RAID 1, right?
RAID 1 = disk mirroring and is what we include in the product (as a
software implementation)
RAID 0 is disk striping *without* parity or any other form of protection
and in fact provides *zero* protection to your system. If anything, it
makes your system *less* secure, in my opinion, because it introduces
more points of failure (multiple disk drives). Some people do use
disk striping as it can provide a speed increase - but we (e-smith) do
not support it and most likely *never* will.
I assume it was just a typo, but want to make sure we're all on the same
page.

Hmmmm... I haven't run into this problem personally. Somehow you have
to get the master boot record to point to where your e-smith install is.
There's probably an fdisk command to do it. My brain can't think of it right
now.

Hmmm... no, it won't eat up that much space. The funky thing about the
software implementation of RAID1 that Red Hat Linux uses (and that we
then use) is that it requires two disk drives that are identical. Ideally,
even to the identical manufacturer. But at least to the same size,
number of cylinders, etc.
It sounds to me like maybe the RAID1 software got confused by existing
partitions and such and didn't know how to properly set up the system.
My suggestion would be similar to what Darrell said - wipe the drives
completely (both of them) and then try the installation again. You might
also try booting with a DOS floppy that has fdisk and making sure that
the partition table is completely erased.
If after all of that the install still doesn't give you more space,
then there might be other issues we need to look at.

Dan
