Problem: Currently whenever there is metadata split-brain, a variable sh->op_failed is set to 1 to denote that self heal got failed. But if we proceed for data self heal, even code-path of data self heal also relies on the sh->op_failed variable. So if will check for sh->op_failed variable and will eventually fails to do data self heal. So needed a mechanism to allow data self heal even if metadata is in split brain. Fix: Some data structure revamp is done in http://review.gluster.com/#/c/5106/ fix and this patch is based on the above fix. Now we can store which particular self-heal got failed i.e GFID_OR_MISSING_ENTRY_SELF_HEAL, METADATA, DATA, ENTRY. And we can do two types of self heal failure check. 1. Individual type check: We can check which among all four (Metadata, Data, Gfid or missing entry, entry self heal) got failed. 2. In afr_self_heal_completion_cbk, we need to make check based on the fact that if any specific self heal got failed treat the complete self heal as failure so that it will populate corresponding circular buffer of event history accordingly.
