What happens if you run the --assemble --update=revert-reshape command on
these 6 devices (without --force)??
Here's the output
mdadm --assemble --verbose --update=revert-reshape /dev/md127
/dev/sda1 /dev/sdc1 /dev/sdd1 /dev/sdb /dev/sdg1 /dev/sdz1
mdadm: looking for devices for /dev/md127
mdadm: Reshape position is not suitably aligned.
mdadm: Try normal assembly and stop again
What are the steps I need to take to resume the grow, but just enough
to get it to the point I can revert it and see what data I have on the
drives? Or can I force the revert?
I'm stumped. Since your reshape position, while "0%", was 4GB into your
array, there's no way to use --create --assume-clean to fix this.
Unless Neil knows some magic, your data is toast. Sorry.
I guess the only chance is to try and get all the drives that were
reshaping (or copies of them) in a fit state to try and re-assemble the
array. Would the revert work then? Or would the reshape crash on hitting
the first bad sector?
Cheers,
Wol
