Something doesn't match up here. If it can take 15 minutes for a write to
replicate to the second brick, according to the first comment, then it
should take that whole 15 minutes for the control to be returned to the
user, per the second comment.
On similar systems, there are options to have control return to the user
either after the first of two mirrored storage locations is written to, or
to have it wait until after the second is written to. Does Gluster have such
an option? If so, what does it default to?
Sorry if I've missed the documents on that. The documents I've found so far
have an admirable simplicity, but also leave out a lot of details it would
be good to know.
