Mounting a HD under HAL


I am not a Linux wiz, so I may be overlooking something obvious. Under the Gnome Hardware Browser, I see my 40 GB drive (hdb1), however it is not mounted - at least I believe that is the correct term since when I do

# mount

it is not listed. How do I mount hdb1 under HAL?

First make sure it's listed in your fstab with a mount point assigned.

Assuming it's /mnt/somedrive

#mount /dev/hdb1 /mnt/somedrive

Mason -
If I create /mnt/data and type in

#mount /dev/hdb1 /mnt/data

I get a message that /dev/hdb1 is busy. Here is my /etc/fstab:

# This file is edited by fstab-sync - see 'man fstab-sync' for details
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
/dev/VolGroup00/LogVol01 swap swap defaults 0 0
/dev/hdc /media/cdrom auto pamconsole,exec,noauto,managed 0 0
/dev/fd0 /media/floppy auto pamconsole,exec,noauto,managed 0 0

I do not know how to deal with HAL and the /dev/VolGroup00/LogVol01 type entries. These are foreign to me and Fedora 2 running on another box.

Thank you for your assistance...

I don't see /mnt/data assigned to any device in you fstab

Also I don't use that mess so not sure exactly what is what there.

It appears that upon installing the new Fedora 3, I got dumped head first into Logical Volume Manager (LVM), the way Red Hat is managing file systems. After snooping around this and other forums and using Google, I have increased my understanding somewhat about Fedora 3 and it's file system management, yet in no way am I confortable with understanding what is really going on. Here is what I have found out so far:

* The file system is managed by lvm2 (Logical Volume Manager) which creates LVM entries.

* #mount displays

# This file is edited by fstab-sync - see 'man fstab-sync' for details
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
/dev/VolGroup00/LogVol01 swap swap defaults 0 0
/dev/hdc /media/cdrom auto pamconsole,exec,noauto,managed 0 0
/dev/fd0 /media/floppy auto pamconsole,exec,noauto,managed 0 0

* #fdisk -l displays

Disk /dev/hda: 81.9 GB, 81964302336 bytes
255 heads, 63 sectors/track, 9964 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

It appears that the LV size of 112.91 GB is the combined size of the two HD's. In other words, the LVM system has combined the hard drives into one logical entry. Could this be?

Does anyone on this forum have a good understanding of the LVM system in Fedora 3?
