I can't say for sure, but my thoughts:
- It probably has nothing to do with pacemaker, cluster and drbd
- SQL databases use garbage collector, which could do one big transaction
on restart and freed some space
- Filesystem itself may be using some sort of garbage collector, especially
on remounting
