10 Raid1 [start | stop | status | monitor | meta-data | validate-all]
11
13 This resource agent manages Linux software RAID (MD) devices on a
14 shared storage medium. It uses mdadm(8) to start, stop, and monitor the
15 MD devices. Raidtools are supported, but deprecated. See
16 https://raid.wiki.kernel.org/index.php/Linux_Raid for more information.
17
19 raidconf
20 The RAID configuration file, e.g. /etc/mdadm.conf.
21 (required, string, no default)
23 raiddev
25 One or more block devices to use, space separated. Alternatively,
26 set to "auto" to manage all devices specified in raidconf.
27 (required, string, no default)
29 homehost
31 The value for the homehost directive; this is an mdadm feature to
32 protect RAIDs against being activated by accident. It is
33 recommended to create RAIDs managed by the cluster with "homehost"
34 set to a special value, so they are not accidentally auto-assembled
35 by nodes not supposed to own them.
36 (optional, string, no default)
38 force_stop
40 If processes or kernel threads are using the array, it cannot be
41 stopped. We will try to stop processes, first by sending TERM and
42 then, if that doesn't help in 3 seconds, using KILL. The lsof(8)
43 program is required to get the list of array users. Of course, the
44 kernel threads cannot be stopped this way. If the processes are
45 critical for data integrity, then set this parameter to false. Note
46 that in that case the stop operation will fail and the node will be
47 fenced.
48 (optional, boolean, default true)
50 udev
52 Wait until udevd creates a device in the start operation. On a
53 normally loaded host this should happen quickly, but you may be
54 unlucky. If you are not using udev set this to "no".
55 (optional, boolean, default true)
57 force_clones
59 Activating the same md RAID array on multiple nodes at the same
60 time will result in data corruption and thus is forbidden by
61 default.
62 A safe example could be an array that is only named identically
64 across all nodes, but is in fact distinct.
65 Only set this to "true" if you know what you are doing!
67 (optional, boolean, default false)

71 This resource agent supports the following actions (operations):
72 start
74 Starts the resource. Suggested minimum timeout: 20s.
75 stop
77 Stops the resource. Suggested minimum timeout: 20s.
78 status
80 Performs a status check. Suggested minimum timeout: 20s. Suggested
81 interval: 10s.
82 monitor
84 Performs a detailed status check. Suggested minimum timeout: 20s.
85 Suggested interval: 10s.
86 validate-all
88 Performs a validation of the resource configuration. Suggested
89 minimum timeout: 5s.
90 meta-data
92 Retrieves resource agent metadata (internal use only). Suggested
93 minimum timeout: 5s.
94
96 The following is an example configuration for a Raid1 resource using
97 the crm(8) shell:
98 primitive p_Raid1 ocf:heartbeat:Raid1 \
100 params \
101 raidconf=string \
102 raiddev=string \
103 op monitor depth="0" timeout="20s" interval="10s"
104
106 The following is an example configuration for a Raid1 resource using
107 pcs(8)
108 pcs resource create p_Raid1 ocf:heartbeat:Raid1 \
110 raidconf=string \
111 raiddev=string \
112 op monitor OCF_CHECK_LEVEL="0" timeout="20s" interval="10s"
