Boot partiton on seperate hard disk


Hi,
I installed this system ages ago. I think there is something seriously wrong with the partitioning scheme i ended up with.

I have two 1.2gb hard disks. It appears my boot partition is on hard disk a, but hard disk a is only seen as 98mb.

Can i regain the rest of that drive space?

Also, what is none mounted on /dev/shm mean?

This is my set up:
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/hdb1 1.2G 884M 253M 78% /
/dev/hda1 98M 8.8M 84M 10% /boot
none 23M 0 23M 0% /dev/shm

cheers,
karl

From Documentation/filesystems/tmpfs:

2) glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
POSIX shared memory (shm_open, shm_unlink). Adding the following
line to /etc/fstab should take care of this:

tmpfs /dev/shm tmpfs defaults 0 0

Remember to create the directory that you intend to mount tmpfs on
if necessary (/dev/shm is automagically created if you use devfs).

This mount is _not_ needed for SYSV shared memory. The internal
mount is used for that. (In the 2.3 kernel versions it was
necessary to mount the predecessor of tmpfs (shm fs) to use SYSV
shared memory)

Thanks,
fstab already has :
none /dev/shm tmpfs defaults 0 0

Do you know if I can get the rest of the hard drive space from /dev/hda1 which is used as the boot partition?

This is a redhat 9 install.
cheers.
