Hi folks,
I notice that a few people have posted spec files with self-heal in
cluster/afr as well as in cluster/unify. I can't seem to demonstrate
this working, however. Is there a way to get healing functionality
with straigh afr?
Take a simple 2 machine afr mirror for example (spec file below). I
have a brick on machine A doing afr to the brick on machine B and vice
versa. If one of the bricks goes down and I create a file on the
remaining one, is there any way to have healing done with the other
brick comes back up?
In my testing, I don't see any evidence of self-heal in afr even
though several folks have it in their spec files. When I bring the
other machine back online, files that were create while it was down
are never created on the mirror brick.
Can someone with a more intimate knowledge of the code comment on this
? thanks...
