OCF_HEARTBEAT_NFSSER(7) OCF resource agents OCF_HEARTBEAT_NFSSER(7)NAMEocf_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, it should be either
sm-notify or rpc.statd. 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_notify_foreground
Keeps the notify tool attached to its controlling terminal and
running in the foreground.
(optional, boolean, default false)
nfs_smnotify_retry_time
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. Specifying a value of 0 causes sm-notify to
continue sending notifications to unresponsive peers until it is
manually killed.
(optional, integer, no default)
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")
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 p_nfsserver ocf:heartbeat:nfsserver \
params \
nfs_shared_infodir=string \
nfs_ip=string \
op monitor depth="0" timeout="20s" interval="10"
