Installation guide

Note

The number of fail o verd o mai nno d e attributes depends on the number of nodes in

the failover domain. The skeleton fai l o verd o mai n section in preceding text shows

three fai l o verd o mai nno d e elements (with no node names specified), signifying

that there are three nodes in the failover domain.

3. In the fai l o verdo mai n section, provide the values for the elements and attributes. For

descriptions of the elements and attributes, refer to the failoverdomain section of the annotated

cluster schema. The annotated cluster schema is available at /usr/share/d o c/cman-

X. Y . ZZ/cluster_conf. html (for example /usr/share/do c/cman-

3. 0 . 12/cluster_conf. html ) in any of the cluster nodes. For an example of a

fai l o verd o mai ns section, refer to Example 7.8, “A Failover Domain Added to

cl uster.co nf ”.

4. Update the confi g _versio n attribute by incrementing its value (for example, changing

from co nfi g _versi o n= "2" to co nfi g _versio n= "3">).

5. Save /etc/cl uster/cl uster.co nf.

6. (O pti o nal ) Validate the file against the cluster schema (cl uster.rng ) by running the

ccs_co nfi g _val i d ate command. For example:

[root@ example-01 ~]# ccs_co nfi g _val i d ate

Configuration validates

7. Run the cman_too l versi o n -r command to propagate the configuration to the rest of the

cluster nodes.

8. Proceed to Section 7.5, “ Configuring HA Services”.

Example 7.8, “ A Failover Domain Added to cl uster. co nf ” shows an example of a configuration

with an ordered, unrestricted failover domain.
