I'm still guessing because you've never told us what your original mdrun
command was, but if your original command was

gmx mdrun -deffnm md_0_1 -v

and you've not modified any of those output files, then this does a restart
and appends to the output. mdrun will even tell you why it won't restart or
won't append, but you haven't shared the reason with us.

However, you've surely modified some of those original output files in your
attempts, so it can't work any more. Go and do your science, now that you
know what the procedure for a restart is. :-)

Yes, there's a reason we didn't tell you to try that.

This cannot append to md_0_1.log because you've told mdrun the log file is
named (the default) md.log.
