Yes entries of both machines is in /etc/hosts file, and resolving

I used this command from pr009
drbdadm -- --overwrite-data-of-peer primary all

no it is not.
my drbd.conf file is
global { usage-count yes; }
common { syncer { rate 10M; } }
resource r0 {
protocol C;
startup { wfc-timeout 12; degr-wfc-timeout 120; }
net {
cram-hmac-alg sha1;
shared-secret "prolog";
allow-two-primaries;
}
on pr009.prolo.com {
device /dev/drbd1;
disk /dev/hdb10;
address 192.168.10.38:7789;
meta-disk internal;
}
on pr0005.prolo.com {
device /dev/drbd1;
disk /dev/hda6;
address 192.168.10.31:7789;
meta-disk internal;
}
how do i synchronize both primary/primary nodes?
i found that if i unmount and remount after a while i can see pr009
machine updated.
How to define sync timing?
What about /etc/ha.d/resource.d/drbddisk script
i started it with
/etc/ha.d/resource.d/drbddisk r0 start
thanks and regards
