NV+ V2 stuck at booting

Hello

I have been had my NV+ V2 for a few years now without any issue.  It has the latest and last firmware (5.3.11 i think) and is populated with 2x WD 4Tb Red and 2x WD 3Tb Red internally and a usb enclosure attached as well.  I also have Transmission and Sabnzb addons installed and running as well as SSH access enabled.

The issue started today when i noticed that the Transmission website was not accessible from the standard IP.  Everything else on the NAS was working fine.  In the NAS dashboard software it showed the Transmission service as enabled but not running (no green dot).  I wasn't able to enable it from here either after trying.

After this i decided a reboot was the next option, I initiated this from the dashboard and let it run its path. 

15 minutes later i tried to login to the dashboard and it loads but immediately says Device is Offline. Checking the screen on the unit itself just shows "Booting".  I then waited another 15 mintues incase it was doing a long file system check upon boot but it was unchanged.  After this i tried a shut down (by removing power as the power button would not restart it) and it went back to the same status.

The strange part is that the network shares from the NAS appear to be fully opertaional, as well as Transmission, although now Sabnzb is not working.

I'm not an expert by any means of the linux system but looking in SSH i see some bad looking messages about file systems and depreacated SCSI ioctl which i really dont understand.  I have attached the contents of 'dmesg' below.

I have read some threads about similar booting issues and some say it is a bad drive that prevents this.  All the 'smartctl' look normal and don't report any errors.  How can i potentially identify which one is bad before pulling each and trying them on my computer.

Can someone decipher the issue from the below log or point me in the correct next steps for this? My backup of important data is a little old so i think i was going start with that but i don't think i'll have enough room on other devices to back up everything at the moment.

If there are other SSH commands or log files that will be more helpful please let me know.

Thanks in advance.
