affinity towards odd number erasure sets to provide for uniform distribution across nodes*. This is to ensure that same number of drives are pariticipating in any erasure set. For example if you have 2 nodes with 180 drives then GCD is 15 but this would lead to uneven distribution, one of the nodes would participate more drives. To avoid this the affinity is given towards nodes which leads to next best GCD factor of 12 which provides uniform distribution.

### Expiry or removal events

An object that is in transition tier will be deleted once the object hits expiry date or if removed via `mc rm` (`mc rm --vid` in the case of delete of a specific object version). Other rules specific to legal hold and object locking precede any lifecycle rules.

### Additional notes

Tiering and lifecycle transition are applicable only to erasure/distributed MinIO.
