Angry how to mount an LVM to existing system?


Gentlement,

I would like to mount another harddrive do my existim system

My system is Fedora3 and attached another harddisk that have the same fedora3

here is the information of harddrive

0 19551168 hda
1 104391 hda1
2 19446682 hda2
0 390826682 hdc
1 104391 hdc1
2 38973690 hdc2 <--- i want to mount this
0 19005440 dm-0
1 393216 dm-1
0 256000 sda
1 255984 sda1

syntex i have use:
(error occure)

#mkdir /mnt/hdc
#mount /dev/hdc2 /mnt/hdc
mount: you must specify the file system type

now with file system type
#mount -t ext3 /dev/hdc2 /mnt/hdc
mount: wrong fs type, bad option, bad superblock on /dev/hdc2, or too many file systems

I don't know whay... think that my syntax were correct

If you are sure that hdc2 is ext3 you might want to run a e2fsck on the partition before mounting it.

I had a similar problem when I moved away from FC3 to Slack with a 60G harddrive which holds my music and this fixed it for me.

Good morning

You have not created a fs in that hdc2 partition and cannot be mounted
1st you have to create the filesystem on the disk partition /dev/hdc2, for example
mke2fs -j /dev/hdc2 /mnt/hdc2 , that if that partition has not been formatted yet ,i.e it has not been assigned an fs . After that you have to put the entry in /etc/fstab in order to tell the system to mounted anytime that you start your machine , if not you will have to mount it manually

It seems to me you have not assigned a fs yet to that disk partition .

You can do what Walman says if you do not have any information on the Partition you would like to preserve.

Creating a fs *File System( means to "Format" the partition

i have the same issue.

i did this for knoppix live-cd and everything is happy.
http://www.knoppix.net/wiki/LVM2

but when i try it in rh9. it fails:
Code:
[root@hyper mnt]# mount  /dev/hdb2 hdb5
mount: you must specify the filesystem type
[root@hyper mnt]# modprobe dm-mod
modprobe: Can't locate module dm-mod
[root@hyper mnt]# apt-get update

E: Couldn't find package lvm-common
here's what my disk looks like:
Code:
[root@hyper mnt]# fdisk /dev/hdb
 
The number of cylinders for this disk is set to 14593.
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)
 
Command (m for help): p
 
Disk /dev/hdb: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
