[Gluster-devel] Client side AFR race conditions?

[Martin Fick]

I am curious, is client side AFR susceptible to race
conditions on writes?  If not, how is this mitigated? 


In other words, what prevents conflicts when client A
& B both write to the same file?  Could A's write to
subvolume A succeed before B's write to subvolume A,
and at the same time B's write to subvolume B succeed
before A's write to subvolume B?  If so, isn't this
somewhat similar to a split brain operation?  Is there
some form a transaction layer using file version #s
that prevents this?

Thanks for any info you could shed on this,

-Martin
