8.3.x has got fix for this bug. You need "# avoid too tight pacemaker driven "recovery" loop," patch.W dniu 17.12.2013 12:22, Nikita Staroverov pisze:I forgot some important thing. You must use last version of drbd, due to ocf agent bug that can lead to drbd promote fail with error code 17. AFAIK, you nead drbd 8.4.4 at least.Not good, because I have 8.3.11, this is version which is in Debian Wheezy. I would have to switch to Testing to have latest version.Where can I read about that bug to see what to expect?Currently I see no issues (altought it is running only with few resources).
You can check this by looking into ocf agent's promote function:
Good :) function looks like this:
drbd_promote() {
643 local rc
644 local status
645 local first_try=true
646
647 rc=$OCF_ERR_GENERIC
648
649 # Keep trying to promote the resource;
650 # wait for the CRM to time us out if this fails
651 while :; do
652 drbd_status
653 status=$?
654 case "$status" in
655 $OCF_SUCCESS)
656 do_drbdadm primary $DRBD_RESOURCE
657 if [[ $? = 17 ]]; then
658 # All available disks are inconsistent,
659 # or I am consistent, but failed to fence the peer.
660 # Cannot become primary.
