GDS: Global Disk Services

Explanation

Messages output by the daemon are shown below in the order of its severity. There are four levels of severity.

Level of importance	Descriptions	facility.level
HALT	This message is output when an event that will halt all services provided by GDS is detected.	user.crit
ERROR	This message is output when an event that will halt some services is detected.	user.err
WARNING	This message is output when an abnormal event is detected. It will not always result in a service halt.	user.warning
INFO	This message is output to record the daemon operation and the like. Usually, it can be ignored.	user.info

GDS: Global Disk Services

facility.level is the facility and priority of a message passed from the GDS daemon to syslogd(1M). The output destinations of messages are defined in the /etc/syslog.conf configuration file of syslogd(1M) and can be changed by modifying the definitions in /etc/syslog.conf. For details, see the description about syslog.conf(4) in this manual.
