Name

ocf_heartbeat_nfsserver — Manages an NFS server

Synopsis

nfsserver [ start | stop | monitor | meta-data | validate-all ]

Description

Nfsserver helps 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.

Supported Parameters

nfs_init_script

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. (optional, string, default /etc/init.d/nfsserver)

nfs_notify_cmd

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. (optional, string, default /sbin/sm-notify)

nfs_shared_infodir

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. (required, string, no default)

nfs_ip

The floating IP address used to access the nfs service (required, string, no default)

Supported Actions

This resource agent supports the following actions (operations):

start

Starts the resource. Suggested minimum timeout: 40.

stop

Stops the resource. Suggested minimum timeout: 20s.

monitor

Performs a detailed status check. Suggested minimum timeout: 20s. Suggested interval: 10.

meta-data

Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5.

validate-all

Performs a validation of the resource configuration. Suggested minimum timeout: 30.

Example

The following is an example configuration for a nfsserver resource using the crm(8) shell:

primitive example_nfsserver ocf:heartbeat:nfsserver \
  params \
    nfs_shared_infodir=string \
    nfs_ip=string \
  op monitor depth="0" timeout="20s" interval="10"
