OCF_HEARTBEAT_EXPORT(7) OCF resource agents OCF_HEARTBEAT_EXPORT(7)NAMEocf_heartbeat_exportfs - Manages NFS exports
SYNOPSIS
exportfs [start | stop | monitor | meta-data | validate-all]
DESCRIPTION
Exportfs uses the exportfs command to add/remove nfs exports. It does
NOT manage the nfs server daemon. It depends on Linux specific NFS
implementation details, so is considered not portable to other
platforms yet.
SUPPORTED PARAMETERS
clientspec
The client specification allowing remote machines to mount the
directory over NFS.
(required, string, no default)
options
The options to pass to exportfs for the exported directory.
(optional, string, no default)
directory
The directory which you wish to export using NFS.
(required, string, no default)
fsid
The fsid option to pass to exportfs. This can be a unique positive
integer, a UUID, or the special string "root" which is functionally
identical to numeric fsid of 0. 0 (root) identifies the export as
the root of an NFSv4 pseudofilesystem -- avoid this setting unless
you understand its special status. This value will override any
fsid provided via the options parameter.
(unique, required, string, no default)
unlock_on_stop
Relinquish NFS locks associated with this filesystem when the
resource stops. Enabling this parameter is highly recommended
unless the path exported by this exportfs resource is also exported
by a different resource.
(optional, boolean, default 0)
wait_for_leasetime_on_stop
When stopping (unexporting), wait out the NFSv4 lease time. Only
after all leases have expired does the NFS kernel server relinquish
all server-side handles on the exported filesystem. If this
exportfs resource manages an export that resides on a mount point
designed to fail over along with the NFS export itself, then
enabling this parameter will ensure such failover is working
properly. Note that when this parameter is set, your stop timeout
MUST accommodate for the wait period. This parameter is safe to
disable if none of your NFS clients are using NFS version 4 or
later.
(optional, boolean, default 0)
rmtab_backup
Back up those entries from the NFS rmtab that apply to the exported
directory, to the specified backup file. The filename is
interpreted as relative to the exported directory. This backup is
required if clients are connecting to the export via NFSv3 over
TCP. Note that a configured monitor operation is required for this
functionality.
To disable rmtab backups, set this parameter to the special string
"none".
(optional, string, default ".rmtab")
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: 10.
monitor
Performs a detailed status check. Suggested minimum timeout: 20.
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 exportfs resource using
the crm(8) shell:
primitive p_exportfs ocf:heartbeat:exportfs \
params \
clientspec=string \
directory=string \
fsid=string \
op monitor depth="0" timeout="20" interval="10"
