1. What's your approximate disk size (or sum of disks) ?
2. If your total block counts from blockmap output matches your disk size,
> zone 0 1095221 0 18446744073709486080 2.00784e+06
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.
