I have just rolled back to -p7 and run a number of test builds in
poudriere (the jails still have the -p8 user land). I see the same as
Matthias and Christoph, the rollback to the -p7 kernel/zfs resolved
the build problems, there are no NUL byte files generated anymore.
Adding markj@ to the discussion. Mark, the TLDR so far:
- One of the zfs patches in -p8 seems to cause erroneous writes.
- We noticed because of many build failures with poudriere (presumably
highly io-loaded during build).
- Symptom: Production of files with large runs of NUL-bytes.
