Multipath devices causing 100% diskspace usage.

Multipath devices causing 100% diskspace usage.

Symptom


Disk space usage reaches 100% with multipath devices.

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.

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.

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