It's better to use thin provisioned volumes to have snapshots comes for free (copy on write) and are better for SSDs
Thin provisioned volumes are created from a “pool”.
lvcreate -L 100G --thin vg/thin
Then create volume within the pool:
lvcreate -n myvol -T vg/thin -V 10G
Then to take a snapshot:
lvcreate -kn -n myvol_snap -s vg/myvol
To restore the snapshot
lvremove vg/myvol lvrename vg/myvol_snap vg/myvol
Create a volume:
lvcreate -L10G -n myvol vg
Take a snapshot, you MUST give a size here, the diff between snapshot and original volume will be stored here. In case of this space being consumed, the snapshot is corrupted :/
lvcreate -L2G -s -n myvol_snap vg/myvol
To restore the snapshot
lvconvert --merge vg/myvol_snap
