Debian man lvcreate snapshot
The Red Hat Enterprise Linux release 6. Repeat from 1 to 4 times to increase the detail of messages sent to stdout and stderr. Down-sizing a file system is a delicate process. The second form supports the creation of snapshot logical volumes which keep the contents of the original logical volume for backup purposes. While writethrough may be slower for writes, it is more resilient if something should happen to a device associated with the cache pool LV. This operation requires 2 devices because the log is in memory.

A LVM snapshot can be used to backup a logical volume data while it is. LVM Snapshots are Point in Time copies of LVM Logical Volumes. Follow the link below to download the 'Complete Guide to LVM2 in Linux'.
But for example, snapshots of active origin can only be created in the active state so -an cannot be used with --type snapshot.

Thin snapshot shares same blocks within the thin pool volume. Certain LV types require more physical extents for data redundancy or metadata. See lvconvert 8 for online conversion to thin volumes with external origin.
Pool volumes cannot have persistent major and minor numbers.
