I would like to change the configuration adding 2 more 300 GB disk and creating a a big raid disk : (75+75+150) + 300 + 300 = 600 GB (a little less). My questions are : Is this possible in gvinum ? In other words, can i use for a raid a concatenated disk ? If yes, how ? Someone can point me to some examples or how-tos (googling i didn't find anything to that specific configuration) ? If i can do this (weird thing, i admit it :-) ) , must i destroy the concatenated file system ? (my answer to this question is "yes, of course, stupid", but ...) Best regards, Paolo Tealdi Ing.
