The latest version gluster 2.0.0 has a bug in I/O xlator:
if we have this:
volume iothreads
type performance/io-threads
option thread-count 8 # deault is 1
subvolumes <x>
end-volume
it reported:
iothreads: '8' in 'option thread-count 8' is out of range [16 - 256]
it works fine when we were at gluster 2.0.0rc4. Looks some bugs introduced after rc4.
Please let us know when it got fixed.
thanks
Doug
