Question suse server 8.0 on hp server problem

machine:
Hp Proliant DL145/Opterom 2.4GH
2*72 GBB SCSi hdd,
suse:
suse linux Enterprose server 8.0 for Amd 64

problem:
1. can not boot properly. have to use installation disk to boot it: enter installation and choose "boot from existing installation" and this is the only option. ( just use the boot disk and enter the boot up parameters won't work either. The bootloader is grup and doesn't work either. )
after boot it from installation disck, I checked the boot.msg and boot.omsg in /var/log directory. and there are some wiered stuffs:
boot.omsg:
Inspecting /boot/System.map-2.4.19
Loaded 13874 symbols from /boot/System.map-2.4.19.
Symbols match kernel version 2.4.19.
Error seeking in /dev/kmem

Symbol #ext3, value a019a000

Error adding kernel module table entry.

klogd 1.4.1, log source = ksyslog started.
<4>FAT: bogus logical sector size 0
<3>cramfs: wrong magic

<4>reiserfs: checking transaction log (sd(8,2)) for (sd(8,2))

<4>reiserfs: using ordered data mode
<4>Using r5 hash to sort names
Kernel logging (ksyslog) stopped.
Kernel log daemon terminating.
....

I checked the /dev/sda using fdisk, and some strange file systems exist.

sda1 for swap (starts after 1 and end something like after 10 Gb)
sda2 for / ( located after swap, using up rest of the disk space)
sda3 for compack diagnostic( or something like that) (starts from 1 and ends at 1)

fdisk gives some hints about filesystem order is uncorrect.

so what is wrong here??? can any body help me??? to fix this, should I re-install the system??? and in reinstallation should I change the kernel options???


2. Do you think use 62 GB for /, and don't have other partition is ok for the server? or should there be some other patitions for different directories, like /var and /usr etc???

3. I have been told this server crashed the other day, and I am reponsible to find out the reason. so, what kind of log files should I check? and where is them?
the ones i find is in /var/log.
and in them, there are "warn" and " messages" contain something about that. so are these the ones that I should look into?

Hi,

There are several points that are worth considering here. The server has been built using the defaults from Suse Linux Enterprise Server 8.0, this has resulted in some of your problems.

I would recommend that the disk be re-partitioned to something like the following.

In addition your partition /dev/sda3 would appear to be part of the problem with the boot, it may be what is stopping grub from working. I would suggest that the disk is partitioned using fdisk and then the OS is reinstalled.

A little understanding of the sizes of the amount of space required for data and applications is required here.
