Original Infrant ReadyNAS NV powers up but not responding

Well I've been rooting around the rabbit hole for a while now and I'm finally up for air. I was trying to use System Rescue CD but that was a dead end as it was too hard for me to add the necessary software without apt-get.  I switched and set up a live persistent USB with Mint 18 and was able to access the files. As we speak they are being transfered to another drive. The USB was very easy to setup using Windows software here: https://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/

As many here know, the key was to use "fuseext2". Not "fuse-ext2" and not "mount".   For those who are reading this without seeing alot of other info the SPARC versions of the ReadyNAS NV with version 4.x firmware use a non-standard 16k block size so fuseext2 is the only one that will play nice-ish. I still could not access the mounting with any GUI applications on Mint and it would lock up the LV if I tried. With my level of knowledge the only way out at that point was a reboot.

The following instructions posted elsewhere will work.  Just use the right mounter fuseext2 and do not add a dash.  That was a huge time waster for me.

(1) sudo su
(2) apt-get install fuseext2
(3) apt-get install lvm2
(4) modprobe fuse
(5) vgscan
(6) vgchange -ay c
(7) fuseext2 -o ro /dev/c/c /mnt
(7) fuseext2 -o ro -o sync_read /dev/c/c /mnt
That’s it!!!
You can now see the mounted files in the /mnt directory

While the clues were there, it took a long time for me to put them together. On an unsuccessful mount, Mint gives some advice to check the dmesg using

where I found this:

Googling the message found someone with the same issue and that fuseext2 must be used to accommodate the nonstandard block size. With that change, it was off to the races and plodding through authoring the proper rsync and find commands to get what I wanted.

I still like the tool set on the SytemRescueCD and while it can be done, I don't think I am at the level to add the software required to this live CD. It is a shame that it is not easier as there are always new (or old) tools that come along a person might need or want when troubleshooting.

Thank you very much for the time you spent considering my challenge. Just knowing there are knowledgeable people like you willing to help lowered the anxiety greatly.
