Well, of course: if one write fails, the target zone write pointer will not advance as it should have, so all writes for the same zone after the failed one will be unaligned and fail. Is that what you are talking about ? With the fixes applied to rc3, the automatic error recovery in the block layer is gone. So it is up to the user (FS, DM or application) to do the right thing. -- Damien Le Moal Western Digital Research
