[Pacemaker] drbd doesn't work on simple 2-node cluster.

[Daniel Qian]

it seems on the new versions of corosync/pacemaker you will have to specify monitor interval for both master and slave drbd resource. I had this problem before but not sure if you are having the same.

  Hi, 

  I'm trying to install a simple 2-node cluster, drbd/failover-IP/filesystem. 
  Followed the usual examples, wich are mostly the same. I got this working before, but now it doesn't work anymore. 
  The problem (i think) is this (from de log): 

  Feb  9 14:03:04 test1 pengine: [5152]: notice: clone_print:  Master/Slave Set: ms_drbd_websites

  Feb  9 14:03:04 test1 pengine: [5152]: notice: LogActions: Leave resource drbd_websites:0#011(Stopped) 

  Why can't my drbd not run anywhere? Must I tell my the drbd-resource which nodes it can use or something? 
  (PS the drbd alone without the cluster-stuff is working) 

  My config: 

  Debian Lenny

  drbd.conf: 

  global { 
    usage-count yes; 
  }

    protocol C; 
  } 
  resource r0 { 
    device /dev/drbd0; 
    meta-disk internal; 
    on test1 { 
      disk      /dev/sda11; 
      address   10.100.5.1:7789; 
    } 
    on test2 { 
      disk      /dev/sda10; 
      address   10.100.5.2:7789; 
    } 
  } 


  Thanks in advance for your help.
