'fdisk -l /dev/hda' or 'sfdisk -l /dev/hda' where your hard-drive is the device '/dev/hda'.

If your hard-drive is something other than that, use that device name.

To find out what it's device name is, use 'mount', and strip off the trailing number from one of the listed device nodes.

What user are you doing it as?

Also, please show us the output of the command 'mount'.

that device doesn't exist!!!

a valid device is
/dec/cciss/c0d0

or

/dev/cciss/c0d0p1

check thru
ls /dev/cciss/cXdYpZ

Peace, R.

The first half of what Roberto was saying was precisely correct. I didn't pick up on the trailing 'p'.

The actual container (logical disk) is the device node:

/dev/cciss/c0d0

So you want to use:

fdisk -l /dev/cciss/c0d0

The 'p[0-9]' is the partition number of the disk 'd0' on controller 0 ('c0').

It does all make sense ;) A simple 'ls -l /dev/cciss | more' will show all of the previously created device nodes. Browsing through them should make sense now.

with RH AS I suggest using
parted
instead of fdisk

Hi,

-s partition
The size of the partition (in blocks) is printed on the standard output.

to save your caculation, so, it's

fdisk -s /dev/cciss/c0d0p1
fdisk -s /dev/cciss/c0d0p2
..........
fdisk -s /dev/cciss/c0d0p11

Regards !
