never mind file systems... is that one raid set? do you have any idea
how LONG rebuilding that is going to take when there are any drive
hiccups? or how painfully slow writes will be until its rebuilt? is
that something like 22 x 2TB or 16 x 3TB? I'll bet a raid rebuild
takes nearly a WEEK, maybe even longer..
I am very strongly NOT in favor of raid6, even for nearline bulk backup
storage. I would sacrifice the space and format that as raid10, and
have at LEAST a couple hot spares too.
