Do you realise that you need to resize the device "/dev/md2" before you can resize the filesystem that is stored in "/dev/md2". > Nothing is failing it just seems to be at a max size.

I guess that if you mdadm -S /dev/md2 mdadm -A /dev/md2 --update=device-size /dev/...list.of.devices mdadm -G /dev/md2 --size=max resize2fs /dev/md2 then it might work. Or maybe it'll corrupt everything. I cannot really be sure because I am being forced to guess. Commands like: mdadm --examine /dev/* mdadm --detail /dev/md* cat /proc/partitions cat /proc/mdstat dmesg | tail -100 are the sort of things that are useful - not "I tried something and it didn't work"...
