{kb-symptom}
Disk space usage reaches 100% with multipath devices.


{kb-cause}
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.


{kb-resolution}
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.
{code}
blacklist { 
devnode "^(hcp|cdp)[0-9]*" 
wwid * 
}
