I have tried that, but had to build from source as Gluster on FreeBSD is
not much maintained.

Now when I try to mount.glusterfs, I get the following error:

 [quick-read.c:1193:check_cache_size_ok] 0-gv0-quick-read: Cache size 134217728 is greater than the max size of 0

I confirm that the performance.cache-size of the volume is actually

on at gluster:~$ sudo gluster vol get gv0 all|grep cache-size
[sudo] password for on:
performance.cache-size                  32MB
performance.cache-size                  128MB

Where is the value 0 comming from? From my FreeBSD client I guess, how
to change that?

And why is the volume reporting 2 diffrent values for
