Stickiness
Stickiness is additive in groups. Every active member of the group will contribute
its stickiness value to the group’s total. So if the default
resource-stickiness
is
100
and a group has seven members (five of which are active), then the group
as a whole will prefer its current location with a score of
500
.
Resource Monitoring
To enable resource monitoring for a group, you must configure monitoring sepa-
rately for each resource in the group that you want monitored.
NOTE: Empty Groups
Groups must contain at least one resource, otherwise the configuration is not
valid.
Procedure 4.9 Adding a Resource Group
1 Start the Linux HA Management Client and log in to the cluster as described in
Section 4.1, “Linux HA Management Client” (page 32).
2 In the left pane, select Resources and click Add > Group.
3
Enter a unique
ID
for the group.
4 Below Options, set the Initial state of resource and click Forward.
5
In the next step, you can add primitives as sub-resources for the group. These
are created similar as described in Procedure 4.1, “Adding Primitive Resources”
(page 34).
6 If all parameters are set according to your wishes, click Apply to finish the confi-
guration of the primitive.
7 In the next window, you can continue adding sub-resources for the group by
choosing Primitive again and clicking OK.
When you do not want to add more primitives to the group, click Cancel instead.
The next window shows a summary of the parameters that you have already de-
fined for that group. The Meta Attributes and Primitives of the group are listed.
