Bug #16553
Removing Writeback Cache Tier Does not clean up Incomplete_Clones
0%
Description
It seem that the issue related to bug #8882 still happen on Infernalis (v9.2.1). After removing the writeback cache by following procedure on http://docs.ceph.com/docs/infernalis/rados/operations/cache-tiering/ the ex cachepool become has incomplete_clones flag and still leaves min_read_recency_for_promote and min_write_recency_for_promote flags. Beside, the ex storagepool become has lfor flag. Due to this condition (especially incomplete_clones flag on ex cachepool), I cannot use the same cachepool to build new cache tier with following error message.
Error ENOTEMPTY: tier pool {cachepool} has snapshot state; it cannot be added as a tier without breaking the pool
Anyway, I can delete this ex cachepool.
