OK, good work. It seems:
- sdb1 is marked with a partition type ext2, but hasn't been formatted 
with that file system yet. To be sure, perhaps try fsck.vfat and others, 
which should also fail... If so depending on the size you might like to 
make this your /home partition. Another alternative is to mark it as 
LVM, then add it to the VG0, and then extend an existing or add a new LV 
within that space.
- sdb2 is marked ext2, and has been formatted ext2, and has the normal 
boot files on it.
- sdb3 is marked LVM. The complete space is one physical volume {LVM 
PV}. A VG has been created that uses that PV called VolGroup00. There 
are at least two Logical Volumes created within that VolGroup00. 
LogVol00 {guess} is 146GB ext2 mounted as /, LogVol01 is 2GB swap, and 
there is a tiny bit of space {32MB} that is within the PV, but is not 
assigned to an LV {and might be too small to do so}.
-- the space free on the LV00 ext3 partition is 131GB.

I don't know what might have made it stop being bootable, and then 
suddenly be bootable again. How are you telling the machine to boot from 
the second hard disk ? Where there any action commands issued that you 
can remember ?
