5.10 Removing a Cluster Resource
To remove a cluster resource you need the relevant identifier. Proceed as follows:
1
Run the
crm
command as system administrator. The prompt changes to
crm(live)
.
2 Run the following command to get a list of your resources:
crm(live)# resource status
For example, the output can look like this (whereas myIP is the relevant identifier
of your resource):
myIP (ocf::IPaddr:heartbeat) ...
3
Delete the resource with the relevant identifier (which implies a
commit
too):
crm(live)# configure delete YOUR_ID
4
Commit the changes:
crm(live)# configure commit
5.11 Configuring a Cluster Resource
Group
One of the most common elements of a cluster is a set of resources that needs to be lo-
cated together. Start sequentially and stop in the reverse order. To simplify this confi-
guration we support the concept of groups. The following example creates two primitives
(an IP address and an email resource):
1
Run the
crm
command as system administrator. The prompt changes to
crm(live)
.
2 Configure the primitives:
crm(live)# configure
crm(live)configure# primitive Public-IP ocf:IPaddr:heartbeat \
