Hi, I have a ReadyNAS NV+ v2, running RAIDiator 5.3.12 firmware. I replaced the drive in bay #4 after seeing these warnings in the logs (newest entry shown first): Disk failure detected. Detected ...

That's the OS partition, not the data volume. Are those the only file systems you are seeing?
Yes, this is all the output I get when running df -h

When I run fdisk, I can see the 4 3TB drives listed:

Here is the contents of /etc/fstab in case that helps:

sysfs /sys sysfs defaults 0 0

/dev/c/c /c ext4 defaults,acl,nodelalloc,user_xattr,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0,noatime 0 2
fdisk won't show anything useful here. But it's clear from the df -h that the system hasn't mounted the data volume.
Do you have a backup of the data?
Unfortunately I don't have a backup of the data, so hoping to be able to figure out how to get access to it.

Understood. I am thinking you have issues on multiple disks. Unfortunately the DM disks (particularly the 3 TB models) are problematic in RAID arrays.
One option is to use Netgear's data recovery service ( https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service ).
Some folks have reported success with a recovery tool called ReclaiMe. That has the benefit that you can see what it will recover before you purchase it. It does require that you be able to connect your drives to a Windows PC.
These are expensive options, but I think any data recovery is going to cost you.
