mount an external usb lvm

scc28y · 09-03-2006, 04:57 PM

Hi, I just purchased a new usb hard drive enclosure and connected my old linux hard drive into the enclosure. I am trying to mount it. It has two partitions:

Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 19457 156183930 8e Linux LVM

Can someone please tell me how I can mount /dev/sda2 onto my new linux machine? Here is the info of the hard drive on my new linux machine:

Device Boot Start End Blocks Id System
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 4870 39013852+ 8e Linux LVM

All I ask is a simple command which will help me to mount /dev/sda2.

thanks.

Stanley

Well, create a new folder which will be the mounting point of the partition you want to mount. Then simply give the following command to the console:

mount -t ext3 /dev/sda2 /mount_point_path

Replace ext3 with the filesystem your partition has.

Hi, thanks for your reply but my /dev/sda2 is a LVM type partition so simple ext3 does not work. Please help.

Try without the type of the partition.

If not then I've found the next information on a different forum. It might help you:

You have to figure out what the volume group is by running

vgdisplay

Then you need to find out what the logical volume is by running

lvdisplay

Inside /dev, you'll find some kind clue as to how to mount them. Typically, it will be under something like /dev/mapper/[volume group]/[logical volume].

mount -t {ext2|ext3|xfs|reiserfs|etc} /dev/mapper/[volume group]/[logical volume] /mnt/[mount point]

After you run vgchange, then the VolumeGroups should be available under /dev/VolGroup00 (or whatever the VG's name is), and you can mount them using 'mount' as if they were normal block devices...
