This defines a collection of resources, known as a resource
41
group or cluster service.
44
Defines a service (resource group).
48
<parameter name="name" unique="1" required="1" primary="1">
50
This is the name of the resource group.
55
<content type="string"/>
58
<parameter name="domain" reconfig="1">
60
Failover domains define lists of cluster members
61
to try in the event that a resource group fails.
66
<content type="string"/>
69
<parameter name="autostart" reconfig="1">
71
If set to yes, this resource group will automatically be started
72
after the cluster forms a quorum. If set to no, this resource
73
group will start in the 'disabled' state after the cluster forms
77
Automatic start after quorum formation
79
<content type="boolean" default="1"/>
82
<parameter name="exclusive" reconfig="1">
84
If set, this resource group will only relocate to
85
nodes which have no other resource groups running in the
86
event of a failure. If no empty nodes are available,
87
this resource group will not be restarted after a failure.
88
Additionally, resource groups will not automatically
89
relocate to the node running this resource group. This
90
option can be overridden by manual start and/or relocate
96
<content type="boolean" default="0"/>
99
<parameter name="nfslock">
101
Enable NFS lock workarounds. When used with a compatible
102
HA-callout program like clunfslock, this could be used
103
to provide NFS lock failover, but at significant cost to
104
other services on the machine. This requires a compatible
105
version of nfs-utils and manual configuration of rpc.statd;
106
see 'man rpc.statd' to see if your version supports

<shortdesc lang="en">
110
Enable NFS lock workarounds.
112
<content type="boolean" default="0"/>
115
<parameter name="nfs_client_cache">
117
On systems with large numbers of exports, a performance
118
problem in the exportfs command can cause inordinately long
119
status check times for services with lots of mounted
120
NFS clients. This occurs because exportfs does DNS queries
121
on all clients in the export list.
123
Setting this option to '1' will enable caching of the export
124
list returned from the exportfs command on a per-service
125
basis. The cache will last for 30 seconds before expiring
126
instead of being generated each time an nfsclient resource

<parameter name="recovery" reconfig="1">
138
This currently has three possible options: "restart" tries
139
to restart failed parts of this resource group locally before
140
attempting to relocate (default); "relocate" does not bother
141
trying to restart the service locally; "disable" disables
142
the resource group if any component fails. Note that
143
any resource with a valid "recover" operation which can be
144
recovered without a restart will be.

initial startip. If the other service stops, this

183
Maximum restarts for this service.
185
<content type="string" default="0"/>
188
<parameter name="restart_expire_time">
190
Restart expiration time. A restart is forgotten
191
after this time. When combined with the max_restarts
192
option, this lets administrators specify a threshold
193
for when to fail over services. If max_restarts
194
is exceeded in this given expiration time, the service
195
is relocated instead of restarted again.

204
<parameter name="priority">
206
Priority for the service. In a failover scenario, this
207
indicates the ordering of the service (1 is processed
208
first, 2 is processed second, etc.). This overrides the
209
order presented in cluster.conf. This option only has
210
an effect if central processing within rgmanager is turned
