[tasikputri]

Hi all... I'm new in Linux. i'm installing a Linux system just simply following guide by fellow friends comunity.
Currently, my box are having 2 HDD with 35GB each capacity. Displaying in GNome (36.2 GB Encrypted Data).

During installation, I'd selected :
*Remove Linux partitions on selected drives and create default layout
*The "Encrypt system" option

View from terminal :

# /sbin/fdisk -l

Disk /dev/sda: 36.4 GB, 36401315840 bytes
255 heads, 63 sectors/track, 4425 cylinders

In Gnome desktop, when I right click and select mount volume, it will display :
"Unable to mount location. Internal error: No mount object for mounted volume"

Can fellow friends give me some help on mounting these drives.

You are using LVM and you can not mount it using mount command.
Post the output of df -h command here.

Currently my box is at other location. I'll post it later.

I cannot mount the drives (HDD). When I try to mount the drives it will give me error "Unable to mount location. Internal error: No mount object for mounted volume"

As I mentioned earlier, according to output of fdisk command, you have LVM partitions. These Volumes are like Extended Partitions only. You can't mount it using mount command. You have to activate it and mount volumes available inside LVM.

Sorry, yup both of the drives /dev/sda dan /dev/sdb are LVM.

Can u show me how to activate these HDD.
After activating it, what should I do?

I want to install my JBOSS server at /dev/sda and
PostgreSQL DB on /dev/sdb.

Isn't Fedora booting up fine? You don't have to mount any partition for package installation.
You will face problems during Package installation because Fedora 10 is not supported by Fedora Team now. Its life cycle is over.

Fedora is booting up fine. I'd already update Fedora using yum update. I also installed VNC server over it. Ican connect to my fedora remotely using putty and vnc viewer.

I just want to access the two drives.

Is it a same hard disk where you have installed Fedora? Post the output of df -h command here.

[tasikputri]

Sorry for the late reply. Attach is the output of df -h

[root@xxx ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
65G 3.1G 59G 6% /
/dev/sda1 190M 18M 163M 10% /boot
tmpfs 505M 292K 505M 1% /dev/shm

You have to mount LVM of /dev/sdb1 manually.
Execute this

vgchange -a y

Its will activate VolumeGroup. Execute mount command to mount volume after that.
