This is 97652 1k units (matching your /proc/partitions output) and 195304 512-byte sectors (matching the partition table output). So that all looks consistent. So if xfs is doing: >>> md_d0p2: rw=0, want=195311, limit=195304 >>> XFS: empty log check failed it surely does seem to be trying to read past the end of what even it thinks is the end of its log. And, with your geometry I can reproduce this w/o md, partitioned or not. So looks like xfs itself is busted: loop5: rw=0, want=195311, limit=195304 I'll see if I have a little time today to track down the problem.
