I've a setup with 2 active-active nodes on debian etch, drbd 8.0.11,
hosting a samba server on the shared resource.

I often run into a problem: when ocfs2 panics one of the machine, upon
reboot drbd starts, connect, but makes the host primary only after some
time. in the meantime mountall runs and fails because the partition is
not primary! so i need to manually mount it later. can I avoid it?

here's my conf:

global {
    usage-count no;

resource r0 {
  protocol C;
  handlers {
    pri-on-incon-degr "echo o > /proc/sysrq-trigger ; halt -f";
    pri-lost-after-sb "echo o > /proc/sysrq-trigger ; halt -f";
    local-io-error "echo o > /proc/sysrq-trigger ; halt -f";
    outdate-peer "/usr/local/bin/gestisci_split_brain.sh";

  startup {
    wfc-timeout 120;
    degr-wfc-timeout 120;
    become-primary-on both;

  disk {
    on-io-error   detach;
    fencing	  resource-only;

  net {
    after-sb-0pri discard-node-file-server-2;
    after-sb-1pri discard-secondary;
    after-sb-2pri disconnect;
    rr-conflict disconnect;

    timeout 600;
    connect-int 11;
    ping-int 11;
    ping-timeout 20;

  syncer {
    rate 10M;
    al-extents 257;

  on file-server-2 {
    device     /dev/drbd0;
    disk       /dev/md1;
    meta-disk  internal;

  on file-server {
    device    /dev/drbd0;
    disk      /dev/sdc1;
    meta-disk internal;
