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

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.

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

Comma separated list of floating IP addresses used to access the nfs service

(required, string, no default)

rpcpipefs_dir

The mount point for the sunrpc file system. Default is /var/lib/nfs/rpc_pipefs . This script will mount(bind) nfs_shared_infodir on /var/lib/nfs/ (can not be changed), and this script will mount the sunrpc file system on /var/lib/nfs/rpc_pipefs (default, can be changed by this parameter). If you want to move only rpc_pipefs/ (e.g. to keep rpc_pipefs/ local) from default , please set this value.

(optional, string, default "/var/lib/nfs/rpc_pipefs")

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.

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

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