Issue

  • When our cluster nodes boot-up cman fails with error:
# service cman start
Starting cluster:
   Loading modules... done
   Mounting configfs... done
   Starting ccsd... done
   Starting cman... failed
/usr/sbin/cman_tool: aisexec daemon didn't start
                                                           [FAILED]
  • We get the same error when trying to start cman manually with command:
# service cman start
