Description
This function is used by the /reserve, /unreserve, /create-volumes, and /destroy-volumes endpoints. It has a few worts:
1. It installs a 5-second filter when rescinding an offer. However, the cluster state might change so that the filter is actually undesirable. For example, this scenario:
- Create DR, make offer
- Create PV => rescinds previous offer, sets filter, makes offer
- Destroy PV => rescinds previous offer
After the last step, we'll wait 5 seconds for the filter to expire before re-offering the DR.
2. If there are sufficient available resources at the target slave, we don't actually need to rescind any offers in the first place. However, _operation() rescinds offers unconditionally.
