Is this true for single-sector, vs. single-ZFS-block, errors? (Yes, it's
pathological and probably nobody really cares.) I didn't see anything in the
code which falls back on single-sector reads. (It's slightly annoying that the
interface to the block device drivers loses the SCSI error status,

Take this for what it is: the opinion on someone who knows less about zfs than

Usually a laptop disk suffers a mechanical failure - and the failure rate

That's usually the case, but single-block failures can occur as well. They're
rare (check the "uncorrectable bit error rate" specifications) but if they
happen to hit a critical fil

Hi Matt,
Interesting proposal. Has there been any consideration if free space being
reported for a ZFS filesystem would take into account the copies setting?
Example:
zfs create mypool/nonredundant_data
zfs create mypool/redundant_data
df -h /mypool/nonredundant_data /mypool/redun
