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. In the event that this option is not set, this agent will attempt to use an init script at this location, ${DEFAULT_INIT_SCRIPT}, or detect a systemd unit-file to use in the event that no init script is detected.

Disable NFSv3 server reboot notifications Keeps the sm-notify attached to its controlling terminal and running in the foreground. Keeps the notify tool running in the foreground. Specifies the length of sm-notify retry time, in minutes, to continue retrying notifications to unresponsive hosts. If this option is not specified, sm-notify attempts to send notifications for 15 minutes.
