I saw similar negative values when updating my test OSD host to 0.67-rc2
from 0.66 this morning; however, I've seen such negative values being
reported at various times over a number of past releases.

I suspect there's a defect in signed-ness handling somewhere, or similar
— however, it appears to be cosmetic and disappears when the OSD replay
completes.

(I've likewise seen impossible values for other statistics being
reported — a while back I saw multiple EBs being reported as being
read/written during a resync between 4 disks, for example.  I suspect
this is another manifestation of a similar problem.)

Cheers,
David
