(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.
