I read a post a couple nights ago about zeroing the superblock on the drives that report no superblock, but it seems they are already zeroed? My lack of experience here isn't helping. Bummer. This is where I'll have to leave it. Did SELinux prevent the superblocks being written? But in that case it should also have prevented them being updated. I'm out of my depth. There's some information out there about doing diagnostics by using hexdump. https://raid.wiki.kernel.org/index.php/Advanced_data_recovery This page is currently a work-in-progress, but maybe it'll give you a few clues. You'll probably be asked to boot into a rescue CD, if you can. You'll need to have a copy of the latest mdadm on hand. Any chance of running lsdrv from a rescue CD? What I will say is do NOT do anything that will write to the drive unless an expert is guiding you. You've had a reshape happen. That will have moved data and stuff around on the disk. If you destroy the existing superblocks they will be a *nightmare* to recreate, as stuff is no longer in the default location. Best of luck.
