Restart single resource

crm resource restart traffix_webui-grp

Stop all cluster resource

crm configure property stop-all-resources=true

Un-stop all cluster resources

crm configure property stop-all-resources=false

Migrate Web UI to a node (and lock

it to stay there)

crm resource migrate traffix_webui-grp sdclab001-02

Remove lock forcing Web UI to run

on particular node

crm resource unmigrate traffix_webui-grp

Relay migration of CPF VIP and

SCTP

crm resource migrate traffix_cpf-vip-grp sdclab001-01

Remove migration of CPF VIP and

SCTP

crm resource unmigrate traffix_cpf-vip-grp

Note: It is recommended in most cases to only perform start/stop operations on top-level

Resource Groups and Clones. Remember to always "unmigrate" resources before and to

"migrate" resources after performing start/stop operations as otherwise the resource will get

stuck on a node. When migrating, use the crm configure edit command that can be applied

from the Linux command line. This opens an editable file that can be modified as shown in the

following example:

location traffix_webui-loc traffix_webui-grp \

rule $id="traffix_webui-loc-rule" -inf: #uname ne sdcvm108-01 and #uname ne

sdcvm108-03

Removing either #uname ne sdcvm108-01or #uname ne sdcvm108-03 will result in

migrating the resource to the other node.

Recurring Resource Failures

4.3.1 Symptom – Current Failure Counts

In response to the crm command to count all the nodes in a SDC site, only some are “counted.”

In the following example, only nodes Node sdclab002-01 and Node sdclab002-09 are counted

and there is a failure to count the other nodes 02-08.

1 2 ... 9 10 11 12 13 14 15 16 17 18 19 ... 41 42
