Yep, I got them both. I added them at the same time, I knew to look at
both to fix them.
Interestingly enough, I never seem to see any performance benefit from
adding io-threads. I suspect that either
a) I'm not utilizing them correctly or
b) My usage and testing doesn't trigger the cases where it's useful.
I've been focusing on fault tolerance and high availability up until
now, so I'm just starting to experiment with the performance
translators. Does anyone have any suggestions for performance
translators to use and where in a config where AFR and Unify are done on
the client side?

And also master has master as its slave for io-threads, might want to
fix it too :)

Yep, it does. Thanks! I knew it was probably a config problem on my
side somewhere, but I figured you would want to know about the segfault.

Oops,
'slave' has 'slave' as its subvolume in the spec. missed that check in the
parser! thanks for notifying. a proper spec should still work for you
though.
thanks,

Trying to start glusterfsd with this config causes a segfault. Removing
io-threads sections results in a running config. Looks like an infinite

This continues on, I haven't had the patience to find the end.
