Disk space usage reaches 100% with multipath devices.

The error occurs when multipath takes control of the snapshot and is not releasing it back to the agent to manipulate and close as needed.

Blacklisting the snapshot devices in the mutipath configuration file (multipath.conf) and restarting the mutipath deamon. The following code can be added to the configuration file.
blacklist { 
devnode "^(hcp|cdp)[0-9]*"
