Nfsserver helps one to manage the Linux nfs server as a failover-able resource in Linux-HA.
It depends on Linux specific NFS implementation details, so is considered not portable to other platforms yet.

<parameters>
<parameter name="nfs_init_script" unique="0" required="0">
<longdesc lang="en">
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.
