[Debian-ha-maintainers] Bug#576511: drbd8-utils: Ships with violent default actions for various drbd fault conditions - may cause dataloss.

[Tim Small]

Package: drbd8-utils
Version: 2:8.3.7-1
Severity: normal

/etc/drbd.d/global_common.conf ships with the following lines enabled:

handlers {
	pri-on-incon-degr "/usr/lib/drbd/notify-pri-on-incon-degr.sh; /usr/lib/drbd/notify-emergency-reboot.sh; echo b > /proc/sysrq-trigger ; reboot -f";
	pri-lost-after-sb "/usr/lib/drbd/notify-pri-lost-after-sb.sh; /usr/lib/drbd/notify-emergency-reboot.sh; echo b > /proc/sysrq-trigger ; reboot -f";
	local-io-error "/usr/lib/drbd/notify-io-error.sh; /usr/lib/drbd/notify-emergency-shutdown.sh; echo o > /proc/sysrq-trigger ; halt -f";

!!

This might sort of be alright if the box is dedicated to drbd, but it
still might not be.  "echo b > /proc/sysrq-trigger" is particularly
nasty, as it will force a reboot without syncing filesystems.

Tim.
