4.4.10. Specifying nodes in fencing topology

Procedure

• The following commands configure nodes node1, node2, and node3 to use fence devices apc1 and apc2, and nodes node4, node5, and node6 to use fence devices apc3 and apc4:

  # pcs stonith level add 1 "regexp%node[1-3]" apc1,apc2
  # pcs stonith level add 1 "regexp%node[4-6]" apc3,apc4

• The following commands yield the same results by using node attribute matching:

  # pcs node attribute node1 rack=1
  # pcs node attribute node2 rack=1
  # pcs node attribute node3 rack=1
  # pcs node attribute node4 rack=2
  # pcs node attribute node5 rack=2
  # pcs node attribute node6 rack=2
  # pcs stonith level add 1 attrib%rack=1 apc1,apc2
  # pcs stonith level add 1 attrib%rack=2 apc3,apc4
