OCF_HEARTBEAT_RAID1(7) OCF resource agents OCF_HEARTBEAT_RAID1(7)

NAME

ocf_heartbeat_Raid1 - Manages Linux software RAID (MD) devices on shared storage

SYNOPSIS

Raid1 [start | stop | status | monitor | meta-data | validate-all]

DESCRIPTION

This resource agent manages Linux software RAID (MD) devices on a shared storage medium. It uses mdadm(8) to start, stop, and monitor the MD devices. Raidtools are supported, but deprecated. See https://raid.wiki.kernel.org/index.php/Linux_Raid for more information.

SUPPORTED PARAMETERS

raidconf
The RAID configuration file, e.g. /etc/mdadm.conf.
(required, string, no default)
raiddev
One or more block devices to use, space separated. Alternatively, set to "auto" to manage all devices specified in raidconf.
(required, string, no default)
homehost
The value for the homehost directive; this is an mdadm feature to protect RAIDs against being activated by accident. It is recommended to create RAIDs managed by the cluster with "homehost" set to a special value, so they are not accidentially auto-assembled by nodes not supposed to own them.
(optional, string, no default)
force_stop
If processes or kernel threads are using the array, it cannot be stopped. We will try to stop processes, first by sending TERM and then, if that doesn't help in 3 seconds, using KILL. The lsof(8) program is required to get the list of array users. Of course, the kernel threads cannot be stopped this way. If the processes are critical for data integrity, then set this parameter to false. Note that in that case the stop operation will fail and the node will be fenced.
(optional, boolean, default true)

SUPPORTED ACTIONS

This resource agent supports the following actions (operations):
start
Starts the resource. Suggested minimum timeout: 20s.
stop
Stops the resource. Suggested minimum timeout: 20s.
status
Performs a status check. Suggested minimum timeout: 20s. Suggested interval: 10.
monitor
Performs a detailed status check. Suggested minimum timeout: 20s. Suggested interval: 10.
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.

EXAMPLE

The following is an example configuration for a Raid1 resource using the crm(8) shell: 
primitive p_Raid1 ocf:heartbeat:Raid1 \
  params \
    raidconf= string \
    raiddev= string \
  op monitor depth="0" timeout="20s" interval="10"
