CRC error prevents hammer reblock. What to do?

I am experiencing problems when running hammer reblock on /var. I get:

# hammer reblock /var
reblock start 8000000000000000:0000 free level 0
Reblock /var failed: Input/output error
Reblocked:
    0/0 btree nodes
    0/0 data elements
    0/0 data bytes

I tried all the reblock- typed like inodes and so, the all pass, it is
reblock-data wich is failing:
# hammer reblock-data /var
reblock start 8000000000000000:0002 free level 0
Reblock /var failed: Input/output error
Reblocked:
    0/0 btree nodes
    0/0 data elements
    0/0 data bytes

in dmesg I get
CRC DATA @ a000000578bf8000/65536 FAILED
same in messages.

What to do from here on? /var contains mail and starts eating up my disk
space because I can't regain any space from it with this error, right?

Any chance to correct the CRC error (or delete the file that causes it)
and fix this?

TIA

Jan
