I will raise a bug for that. Without this patch Hyper-convergence feature won't
work at all on gluster because of o-direct files writes. So merge this patch as
without it, 3.7 works, master works but 3.8 will be broken.

Sharding has been working fine in Hyperconverged setup for a long time now. Marking it as WORKSFORME. Reopen if this is still an issue.
