There are several perils when splitting a cache pool: - split invalidstes pg stats, which disables the agent - a scrub must be manually triggered post-split to rebuild stats - the pool may fill the OSDs during that period. - or, the pool may end up beyond the 'full' mark and once scrub does complete and the agent activate we may block IO for a long time while we catch up with flush/evict Make it a bit harder for users to shoot themselves in the foot.
