Use the information in this section to understand the Sun Cluster HA for Samba fault monitor. This section describes the Sun Cluster HA for Samba fault monitor's probing algorithm or functionality, states the conditions, messages, and recovery actions associated with unsuccessful probing.
For conceptual information on fault monitors, see the Sun Cluster Concepts Guide.
The Sun Cluster HA for Samba fault monitor uses the same resource properties as resource type SUNW.gds, refer to the SUNW.gds(5) man page for a complete list of resource properties used.
Samba
Sleeps for Thorough_probe_interval
Tries to connect to the Samba instance fault monitor share (scmondir), using smbclient, as user <fmuser>. If this fails then the probe will restart the Samba resource.
The smbclient uses the NetBIOS name of the Samba server to verify that the NetBIOS name server works. If this fails then the probe will restart the Samba resource.
If all Samba processes have died, pmf will interrupt the probe to immediately restart the Samba resource.
If the Samba resource is repeatedly restarted and subsequently exhausts the Retry_count within the Retry_interval then a failover is initiated for the Resource Group onto another node.
Winbind
Sleeps for Thorough_probe_interval
Retrieves the defined <ntuser> by using getent passwd <ntuser>. If this fails then the probe will restart the Winbind resource.
If the Winbind resource is repeatedly restarted and subsequently exhausts the Retry_count within the Retry_interval then a failover is initiated for the Resource Group onto another node.
If nscd is on (default) and the defined <ntuser> is cached by the nscd daemon, then getent will return a success even if winbind itself isn't working.
