I have redhat 7.2 running and my users are about to fill the whole hard drive thats in there so i added another hard drive now how do i get linux to allocate the space on the new drive to the users home directory ?

Usually folks create a /home2 on the new drive, and move some (or all) users from /home to /mnt/newdrive/home2. If you do this, remember to specify the new basedir when adding new users. This can cause problems with scripts that reference '/home/user/somefile'.

Alternatively, you can move /home to the new drive, leaving the existing drive just for the system. If you do that, create a symbolic link to the new home so no software changes are needed:

ln -s /mnt/newdrive/home /home

Make sure to automount the new drive in /etc/fstab.

its okay i tried to mkfs and all i get is bad block count if i try to mount it basicly same error what of this ?

Have you formatted your hard drive yet ?

I thought thats what mkfs did

Yes, that is what mkfs does. What filesystem are you using, and can you post the output of the mkfs?

Are you using the '-c -c' option to check for and map out bad blocks?

i am trying to make ext3
with this command mkfs ext3 /dev/hdb

then it returns with this
mkfs 1.23 15-aug-2001 for ext fs 0.5b 95/08/09
mkfs.ext2: bad blocks count - /dev/hdb

and no i am not useing the -c option

Ah, bad syntax.

First fdisk the drive. Delete existing partitions, and add a primary partition for the entire drive (default cylinder extents), and make the partition type 83 (Linux).

then you can format it as ext3 with:

mke2fs -j -m 0 /dev/hdb1

That is assuming that the drive is /dev/hdb; the '1' at the end signifies the first partition.

ahh, Thank you i was wondering what i was doing wrong.
