"The RAID6/RAID5 array", do you mean my RAID array (just this instance), or
you mean "all RAID6/RAID5 arrays created by mdadm" ?

My reply above is unambiguous.  I quoted your array data and gave an
answer that applies to your provided array data.

WRT your other questions, I do not have time to research the answer to
those, and wouldn't spend it on that if I did.  I have never used CentOS
nor Fedora, and don't plan to ever use either.  For those answers,
either wait for someone to answer, or research it yourself.

Cheers,

Thank you Stan!

Now I'm going to try remove the write-intent bitmap and bad block log in the
RAID 6 array to reshape two arrays to same size.
