You might try logging in with "ssh -X".
I think the program is named system-config-lvm. I don't know if it is under /usr/bin/, /sbin/ or /usr/sbin/.
Look in the kernel source for cciss.txt. The cciss.ko kernel module is for compaq array controllers.
The device naming scheme is:
/dev/cciss/c0d0 Controller 0, disk 0, whole device
/dev/cciss/c0d0p1 Controller 0, disk 0, partition 1
/dev/cciss/c0d0p2 Controller 0, disk 0, partition 2
/dev/cciss/c0d0p3 Controller 0, disk 0, partition 3
/dev/cciss/c1d1 Controller 1, disk 1, whole device
/dev/cciss/c1d1p1 Controller 1, disk 1, partition 1
/dev/cciss/c1d1p2 Controller 1, disk 1, partition 2
/dev/cciss/c1d1p3 Controller 1, disk 1, partition 3
Your fdisk -l command looked at the drives and partition tables. The first entry is probably for /boot.
Disk /dev/cciss/c0d0: 73.3 GB, 73372631040 bytes
255 heads, 63 sectors/track, 8920 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/cciss/c0d0p5 406 8920 68396706 8e Linux LVM
The lvm scan also showed /dev/cciss/c0d1 [ 136.67 GB] LVM physical volume
In the 4th column of the fdisk -l listing is the size of the partition in 1024 byte blocks.
So the first controller, first disk, first partition (c0d0p1) is 104.391 MB in size. The Linux LVM partition is 68 GB in size. The root partition is about 1 GB.
These might be raid devices:
/dev/dm-0 [ 5.00 GB]
/dev/dm-1 [ 20.00 GB]
/dev/dm-2 [ 6.00 GB]
/dev/dm-3 [ 2.00 GB]
/dev/dm-4 [ 20.22 GB]
/dev/dm-5 [ 2.00 GB]
/dev/dm-6 [ 4.00 GB]
/dev/dm-7 [ 102.34 GB]
/dev/dm-8 [ 40.00 GB]
I'm not sure. Use the mdadm program to check your raid setup. Check if these devices are linked to or from somewhere else.
Also read the manpages for mdadm and lvm. There may be an /etc/lvm.conf or /etc/lvm/lvm.conf file showing the configuration.
Also look at /etc/fstab and post it. I don't know how large your LVM volume is and if the two lvm partitions are both members.
