No errors, but I noticed it stopped just before 200 gigabytes. The
total size of the plan9 partition is 1.81 terabytes.

A related question: how should I interpret /dev/sdE0/fossil file size?

# ls -l /dev/sdE0/fossil
--rw-r----- S 0 bootes bootes  199405273600 Sep  5 18:35 /dev/sdE0/fossil

Yet:

# con -l /srv/fscons
prompt: df
        main: 196,000,014,336 used + 1,800,341,831,680 free =
1,996,341,846,016 (9% used)

su# disk/fdisk /dev/sdE0/data
cylinder = 8225280 bytes
 * p1                       0 243201        (243201 cylinders, 1.81 TB) PLAN9

Why such mismatch? And could this be related to the write errors?
