A logic volum snapshot could restore the filesystem on ur logical volum. Here's how to do:
# lvcreate --size 100M --snapshot --name snaptest /dev/test-vg/lvol0
This would create a snapshot snaptest of logic volum /dev/test-vg/lvol0, &nbsp;snaptest&nbsp;can be mounted just like lvol0:
# mount /dev/test-vg/snaptest /mount-point
&nbsp;
By the way, here're commands how to operate a test lv:
1. Make partitions with fdisk or on gpt disks with parted.
2. Commands:
pvcreate /dev/sda5
pvcreate /dev/sda6&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;# Create physical volums.
vgcreate test-vg /dev/sda5 /dev/sda6&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;# Create volum group
lvcreate -L 8G test-vg&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; # Create logic volum
3. Other related commands:
pvdisplay vgdisplay lvdisplay
lvremove /dev/test-vg/snaptest&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;# This need to use the absolute path.
