Subject: Two RAID6 questions
Date: Fri, 20 Jan 2006 13:11:44 +0000 [thread overview]
Message-ID: <1137762704.20659.51.camel@kenny> (raw)
(Before I start, thanks to everybody who replied to my previous
questions.)
First, can raidreconf grow a RAID6 device? The man page doesn't seem to
mention RAID6 at all.
Second, with RAID5 or RAID6 my biggest fear is a system crash whilst the
RAID is writing resulting in dirty blocks. Does RAID6 give some sort of
ECC capability when reconstructing? I'm imagining checking the parity of
a RAID block and if it's wrong assuming each block in turn is dirty,
recalculating it from the first parity and then checking the result
against the second parity.
Thanks
John
