In fact, I'm insufficiently familiar with fsck to know why it's reporting fsck-fat, except to suppose that that's the bootsector format. The data partitions themselves are Apple RAID and presumed HFS something. Maybe "fsck -n /dev/md0p1" > might tell you if the filesystem looks OK. > # fsck -n /dev/md0 fsck from util-linux 2.28.2 fsck.fat 4.0 (2016-05-06) FATs differ - using first FAT.
