This Nagios plugin looks at the output of the ‘lvs’ command to find LVM snapshot volumes that are beginning to run out of copy-on-write space. If a snapshot fills up its copy-on-write space, it will fail. This is also a useful way to detect whether some process, such as a backup, failed to release a snapshot volume after finishing with it.
