OCF_HEARTBEAT_NFSSER(7) OCF resource agents OCF_HEARTBEAT_NFSSER(7)
NAME
ocf_heartbeat_nfsserver - Manages an NFS server
SYNOPSIS
nfsserver [start | stop | monitor | meta-data | validate-all]
DESCRIPTION
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.
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 p_nfsserver ocf:heartbeat:nfsserver
params
nfs_shared_infodir=string
nfs_ip=string
op monitor depth="0" timeout="20s" interval="10"
