Name
ocf_heartbeat_Filesystem — Manages filesystem mounts
Synopsis
Filesystem [ start | stop | notify | monitor | validate-all | meta-data ]
Description
Resource script for Filesystem. It manages a Filesystem on a
shared storage medium.
The standard monitor operation of depth 0 (also known as probe)
checks if the filesystem is mounted. If you want deeper tests,
set OCF_CHECK_LEVEL to one of the following values:
10: read first 16 blocks of the device (raw read)
This doesn't exercise the filesystem at all, but the device on
which the filesystem lives. This is noop for non-block devices
such as NFS, SMBFS, or bind mounts.
20: test if a status file can be written and read
The status file must be writable by root. This is not always the
case with an NFS mount, as NFS exports usually have the
"root_squash" option set. In such a setup, you must either use
read-only monitoring (depth=10), export with "no_root_squash" on
your NFS server, or grant world write permissions on the
directory where the status file is to be placed.
Supported Parameters
device
The name of block device for the filesystem, or -U, -L options for mount, or NFS mount specification.
(required, string, no default)
directory
The mount point for the filesystem.
(required, string, no default)
fstype
The optional type of filesystem to be mounted.
(required, string, no default)
options
Any extra options to be given as -o options to mount.
For bind mounts, add "bind" here and set fstype to "none".
We will do the right thing for options such as "bind,ro".
(optional, string, no default)
statusfile_prefix
The prefix to be used for a status file for resource monitoring
with depth 20. If you don't specify this parameter, all status
files will be created in a separate directory.
(optional, string, default .Filesystem_status/)
Supported Actions
This resource agent supports the following actions (operations):
-
start
Starts the resource. Suggested minimum timeout: 60.
-
stop
Stops the resource. Suggested minimum timeout: 60.
-
notify
Suggested minimum timeout: 60.
-
monitor
Performs a detailed status check. Suggested minimum timeout: 40. Suggested interval: 20.
-
validate-all
Performs a validation of the resource configuration. Suggested minimum timeout: 5.
-
meta-data
Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5.
