[Pacemaker] cannot create gfs2 filesystem : can't open device /dev/drbd1: Read-only file system

[Soni Maula Harriz]

and when i restart drbd service on node 2, i found this message :
[root at cluster2 ~]# service drbd restart
Stopping all DRBD resources: .
Starting DRBD resources: [ d(wwwdata) s(wwwdata) n(wwwdata) ]..........
***************************************************************
 DRBD's startup script waits for the peer node(s) to appear.
 - In case this node was already a degraded cluster before the
   reboot the timeout is 0 seconds. [degr-wfc-timeout]
 - If the peer was available before the reboot the timeout will
   expire after 0 seconds. [wfc-timeout]
   (These values are for resource 'wwwdata'; 0 sec -> wait forever)

and this is the drbd config :
include "drbd.d/*.res";
global {
 usage-count yes;
}
common {
 protocol C;
}
resource wwwdata {
 meta-disk internal;
 device  /dev/drbd1;
 syncer {
  verify-alg sha1;
 }
 net {
  allow-two-primaries;
 }
 on cluster1 {
  disk   /dev/vg_cluster1/drbd-demo;
  address  xxx.xxx.xxx.213:7789;
 }
 on cluster2 {
  disk   /dev/vg_cluster2/drbd-demo;
  address  xxx.xxx.xxx.235:7789;
 }
}
