Feature #4490
Updated by Sage Weil about 11 years ago
introduce a pg_pool_t flag for 'full', and/or for max_bytes, objects, etc.
in the monitor code to update the quota field(s)
in the osd, return ENOSPC if the pool is too full, or the flag is set.
if we use the flag, then the monitor needs to adjust it as the pool gets bigger/smaller.
