Hi, seeing as Pascal covered the other base, I can chime in on this one. There is indeed no Pacemaker magic required to protect the disk on your Secondary. DRBD will not allow any access to a DRBD that is in the Secondary role. It does this on kernel level, so you really cannot shoot yourself in the foot (so long as you don't uselessly play with the allow-two-primaries option). Your other assumptions are fair enough, one remark: You may want to cram "colocation bunny_on_fs" and "order bunny_after_fs" into a single "group mq drbd_fs bunny". HTH, Felix
