Just out of curiosity, assuming this is /usr, what does 'du
/var/hammer/usr/snap*/' output does it give the missing inodes for the
snapshots, too?
I noticed something like this here. I had snapshots that didn't give any
messages with the du, but then, after I did $something, I got similar
messages for several snapshots.
I'm feeling kinda concerned because I thought nothing can change my
snapshot integrity.
