I am having a problem mounting a file system on a hard disk that I
installed in a backup computer. The BIOS recognizes the existence of the
hard disk. I am able to use fdisk to partition the disk, and mke2fs to
put an ext3 filesystem on it. Mounting it produces an error. I am NOT
using LVM. This is what I did:
[root@aa2 ~]# fdisk /dev/hdd
The number of cylinders for this disk is set to 58168.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

[root@aa2 ~]#

[root@aa2 ~]# mount /home2
mount: /dev/hdd1 already mounted or /home2 busy
Your system thinks that /dev/hdd1 is already mounted, or /home2 is in use in
some way. Do you have a shell which has /home2 as it's PWD?
Use the command 'fuser /home2' to try to identify what's accessing it.
