Thanks for an option, but it seems that it is not that good in our
situation. I can't waste storage space on bricks for disperse and disperse
volumes require having bricks of the same size. We will start with
distributed volume of uneven size at the beginning. As we are speaking of
archive server, it is not that critical, if some portion of data won't be
available for some time (maintenance time). Having like 22 disks per server
makes the proability of raid5 failure,when 2 or more disks will fail a bit
higher though, so I'll really have to decide something about it :)
