IMPORTANT: CAPACITY_NAME,
WEIGHT_NAME, and weight_value must all
match exactly.
NOTE: A weight (WEIGHT_NAME,
WEIGHT_DEFAULT) has no meaning on a node
unless a corresponding capacity
(CAPACITY_NAME, CAPACITY_VALUE) is
defined for that node.
For the reserved weight and capacity
package_limit, the default weight is always
one. This default cannot be changed in the cluster
configuration file, but it can be overridden for
an individual package in the package
configuration file.
cmapplyconf will fail if you define a default
for a weight but do not specify a capacity of the
same name for at least one node in the cluster.
You can define a maximum of four
WEIGHT_DEFAULTs per cluster.
Can be changed while the cluster is running.
Access Control Policies (also known
as Role Based Access)
For each policy, specify USER_NAME,
USER_HOST, and USER_ROLE. Policies set in the
configuration file of a cluster and its packages
must not be conflicting or redundant. For more
information, see “Setting up Access-Control
Policies” (page 254).
VOLUME_GROUP The name of an LVM volume group whose disks
are attached to at least two nodes in the cluster.
Such disks are considered cluster-aware. The
volume group name can have up to 39 characters
(bytes).
Cluster Configuration: Next Step
When you are ready to configure the cluster, proceed to “Configuring the Cluster ”
(page 242). If you find it useful to record your configuration ahead of time, use the
worksheet in Appendix E.
