How to mount a partition on a LVM logical volume?

  • 772

I had been installing a paravirtualized (PV) guest with Xen on a Logical volume(LV). The installation has seen the LV as a normal hard disk and installed and ext4 and a swap partition on it.

The output of sudo fdisk -l|grep /dev is

Disk /dev/mapper/vg1/lv1: 40GB
/dev/mapper/vg1-lv1-part1   37G 83 Linux
/dev/mapper/vg1-lv1-part2     3  5 Extended
/dev/mapper/vg1-lv1-part3     3 82 swap

I can use fdisk to modify those partitions like that

sudo fdisk -l /dev/mapper/vg1-lv1

But did not manage to mount the partitions anywhere. I tried

sudo mount /dev/mapper/vg1-lv1-part1 /mnt/tmp      // special device does not exist
sudo mount /dev/mapper/vg1-lv1       /mnt/tmp      // wrong fs type error
sudo mount /dev/vg1/lv1/             /mnt/tmp      // wrong fs type error
sudo mount /dev/vg1/lv1/part1        /mnt/tmp     // special device does not exist

So how do I mount the /dev/mapper/vg1-lv1-part1 partition to /mnt/tmp?

lvm
