yes, this is one of your msgs that I lost...thx for this
no gotta forget druid for this...
wondering if I should just dismantle the raid sys...and redo it as you
did from the command line or...
seeing it's a brand new system...nothing really on it...just throw a
fresh (choose auto for the partitions) then make the arrays.
I really would like to try to do what I'm trying to do just for the
experience but lol I don't know who's gonna give out first me or
raid...lol. It just seems hard to believe that this can't be done.
