Cannot Access Partitions on Second Hard Drive
 
I have two hard drives in my machine. On each I have installed Fedora Core 3 (in case one drive crashes I have--theoretically--a back up OS and files). I have tried to mount the partitions on each hard drive from the other, and receive, for example, the following error:

mount: /dev/hdb2 already mounted or /mnt/hdb2 busy

To be clear, here are the drives and partitions:

[/sbin/fdisk -l]
Disk /dev/hda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 9729 78043770 8e Linux LVM

Disk /dev/hdb: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hdb1 * 1 13 104391 83 Linux
/dev/hdb2 14 9729 78043770 8e Linux LVM


I have created the directories /mnt/hdb /mnt/hdb1 /mnt/hdb2


I have tried the commands:


mount /dev/hdb /mnt/hdb
mount /dev/hdb1 /mnt/hdb1
mount /dev/hdb2 /mnt/hdb2

and

umount /dev/hdb umount /mnt/hdb
umount /dev/hdb1 umount /mnt/hdb1
umount /dev/hdb 2 umount /mnt/hdb2

There are no processes or open files on any of these partitions. Attempting to forcibly unmount these partitions does not work (I receive a 'busy' response).

Any help is greatly appreciated.

Thanks,
Ariadne

What is the output of just plain 'mount'?
