[Pacemaker] DRBD secondary to primary when primary lost connection

[Felipe Gutierrez]

Hi Andrew,

I solved the problem doing this on my DRBD configuration.

Thanks.

resource r8 {
handlers {
    fence-peer "/usr/lib/drbd/crm-fence-peer.sh";
    after-resync-target "/usr/lib/drbd/crm-unfence-peer.sh";
    split-brain "/usr/lib/drbd/notify-split-brain.sh root";
}
startup {
}
disk {
    fencing resource-only;
}
net {
    allow-two-primaries;
    after-sb-0pri discard-zero-changes;
    after-sb-1pri discard-secondary;
    after-sb-2pri disconnect;
}
syncer {
    rate 10M;
    al-extents 257;
}
on cloud10 {
    device /dev/drbd8;
    disk /dev/vg_8/lv_8;
    address 192.168.188.10:7789;
    meta-disk internal;
}
on cloud8 {
    device /dev/drbd8;
    disk /dev/vg_8/lv_8;
    address 192.168.188.8:7789;
    meta-disk internal;
}
}
