Mirrors are the best way to preserve data -- very simple to implement, and if a disk crashes, rebuild is just a matter of copying data from the known good disk. If RAID10 is too complicated, I'd say set up a pair of RAID1 volumes via gmirror. That will give you 400G total data. It is not the best way to utilize your capacity, but then, I assume you have 200G drives because disk is cheap these days. Cheers, -danny -- http://dannyman.toldme.com/
