Bad Hammer zone statistics

[Tomohiro Kusumi]

1. What's your approximate disk size (or sum of disks) ?

2. If your total block counts from blockmap output matches your disk size,

this line from blockmap output shows your layer2 metadata probably had
bad (broken) free_bytes.
Can't tell how it was broken from this output though.

3. What are the 10 errors for checkmap ?
You have output before statistics that indicates those errors.
