Hi! I had some phantom issues that are chasing me through this 3.17
merge window period. While chasing those issues, I decided to do an
xfsdump of a v5/finobt XFS system rescued from PEBKAC issues. The

output...

That looks fine for a lack of obvious error messages. However, it
should end like this:

xfsdump: dumping regular file ino 13653555 offset 0 to offset 16554 (size 16554)

What's the inode number progression of a successful dump at the
point at which the incomplete dump ends? i.e. around inode 4194527?
That number is one inode chunk short of 2^22, which implies that
there is a failure or some kind moving from one AG to the next.
The progrssion of inode numbers will tell me whether this is the
case or not...
It is this, run a bit longer to show xfsdump start to dump regular
