Hi,

I am trying to create a drbd device with xfs filesystem

I used to do
#mkfs.xfs /dev/drbd/4

It was ok with the third
But now i cannot do the same because of an error message
#cannot open /dev/drbd/4 : Read-only file system

even if i do before that,

# samba stop
# umount 'all drbd devices'

I installed heartbeat, and DRBD is working in kernel,
---------------------------------------
  my drbd.conf is ...
#
# drbd.conf
resource r0 {

   protocol C;

   incon-degr-cmd "echo '!DRBD! pri on incon-degr' | wall ; sleep 60 ; 
halt -f";

   startup {
     degr-wfc-timeout 120;    # 2 minutes.
   }

   disk {
     on-io-error   detach;
   }

   syncer {
     rate 100M;
     group 1;
     al-extents 257;
   }

   on SVR-LINUX1 {
     device     /dev/drbd/1;
     disk       /dev/hda8;
     address    10.100.1.11:7788;
     meta-disk  internal;
   }

   on SVR-LINUX2 {
     device    /dev/drbd/1;
     disk      /dev/hda8;
     address   10.100.1.21:7788;
     meta-disk internal;
   }
}
resource ext {

   protocol C;

   incon-degr-cmd "echo '!DRBD! pri on incon-degr' | wall ; sleep 60 ;

   startup {
     degr-wfc-timeout 120;    # 2 minutes.
   }

   disk {
     on-io-error   detach;
   }

   syncer {

   startup {

   disk {
