ReadyNAS Pro 6 - Stuck on booting while checking fs

Thinking it might just be a random error, I restarted the device and now it gets to the checking root fs and stops around half way (sometimes more or less). I have tried the following:
Did you upgrade the RAM, or is it still using the default 1 GB?
Did you try using the boot option that skips the FS check?
How full is the OS partition?

NO, still using the default RAM.
Yes, I did try the FS Skip but it still hangs during the Root FS check stage.
Running the following:
# mount --bind / /mnt # du -d1 -h /mnt 4.0K /mnt/tmp 0 /mnt/sysroot 0 /mnt/sys 8.0K /mnt/run 0 /mnt/proc 0 /mnt/opt 0 /mnt/mnt 0 /mnt/media 0 /mnt/home 52.0K /mnt/var 9.5M /mnt/usr 396.0K /mnt/sbin 2.6M /mnt/lib 2.4M /mnt/etc 420.0K /mnt/bin 16.0K /mnt/root 0 /mnt/dev 15.5M /mnt

Some have found that isn't enough, so I now recommend upgrading to between 2 GB and 4GB. That is still inexpensive. 8 GB is possible, but expensive and it is hard to find 4 GB memory sticks that are compatible.

Looks like you are running the boot OS and not the OS partition (that is, you ran start_raids instead of rnutil chroot). The OS is much larger than 15.5M.
You could try mount /dev/md0 /mnt
if that works you could try checking it from ssh.

I was running the check as you outlined here: RN314 - OS partition full? | NETGEAR Communities to be preemptive in your possible next steps.
I had not ran start_raids at the time, just the commands from your reply.
Here is what I get when I run rnutil chroot:
# rnutil chroot root@2H0523RC00354:/# df -h Filesystem Size Used Avail Use% Mounted on /dev/md0 4.0G 1.4G 2.4G 37% / udev 10M 0 10M 0% /dev tmpfs 495M 0 495M 0% /run
