Hi I was going through various conf options to customize a ceph cluster and came across `osd pool default flags` in pool-pg config ref[1]. Though the value specifies an integer, though I couldn't find a mention of possible values this can take in the docs. Looking a bit deeper onto ceph sources [2] a bunch of options are seen at osd_types.h which resemble FLAG_HASHPSPOOL = 1<<0, // hash pg seed and pool together (instead of adding) FLAG_FULL = 1<<1, // pool is full FLAG_DEBUG_FAKE_EC_POOL = 1<<2, // require ReplicatedPG to act like an EC pg FLAG_INCOMPLETE_CLONES = = 1<<3, // may have incomplete clones (bc we are/were an overlay) Are these the configurable options for the osd pool flags? Also in particular what does the `hashpspool' option do?
