OK, so returning to your original response, you suggest increasing the
size of each physical partition and then resizing each of the physical
partitions independently? (/dev/sdwhatever instead of /dev/md6
directly?)

Is there a reason or personal experience you have to not to resize the
RAID-5 directly? I completely trust you as to date I cannot remember
anything you suggested I do that wasn't a good way to do it but doing
/dev/sdwhatever seems problematic if it had been an 8-drive RAID-1
becoming a RAID-5, etc.

Using cfdisk or fdisk, delete the partition and recreate it, USING THE
SAME START BLOCK at a larger size.

Then "resize2fs /dev/sdwhatever" will resize the filesystem to fill the
partition.
