Subject: RAID0 extent sizes?
Date: Fri, 12 Dec 2014 14:54:24 -0800 [thread overview]
Message-ID: <548B7220.1040403@pobox.com> (raw)
I've seen it mentioned here that generally data extents are 1G and
metadata extents are 256M.
Is that per-drive or per-stripe in the case of RAID0?
That is, if I have data mode raid0 across N drives does the system
allocate one 1G extent on each drive making the full stripe allocation
N-gigs; or does it allocate 1/Nth(gig) on each drive making the total
new allocation 1G?
Does the raid0 have any arity constraints (like how raid1 is always
arity-2)?
