It depends on Linux specific NFS implementation details, so is considered not portable to other platforms yet. Manages an NFS server The default init script shipped with the Linux distro. The nfsserver resource agent offloads the start/stop/monitor work to the init script because the procedure to start/stop/monitor nfsserver varies on different Linux distro. Init script for nfsserver The tool to send out NSM reboot notification. Failover of nfsserver can be considered as rebooting to different machines. The nfsserver resource agent use this command to notify all clients about the happening of failover. The tool to send out notification. The nfsserver resource agent will save nfs related information in this specific directory. And this directory must be able to fail-over before nfsserver itself. Directory to store nfs server related information. Comma separated list of floating IP addresses used to access the nfs service IP addresses.
