OK part of my confusion is that you sorta threadjacked, while still being on topic, and didn't realize you weren't the original poster. So you started out with a raid5 from the get go. Original poster had a raid6. I still don't know why you're getting messages: clearing incompat feature flag for RAID56 (0x80) I think that's confusing if you haven't asked for a conversion from raid5 to a non-raid56 profile. -- Chris Murphy
