RN214 Checking file system after firmware upgrade.

The degraded volume message was telling you a drive had failed. Rebooting at that point was not your best option. That bad drive is also likely what's stopping it from properly validating the file system. If you know which drive went bad, remove it with power off and try booting in read only mode. If you don't, try with each set of 3 drives till it boots. Once you know it will boot read-only, then try a full boot and replace the bad drive with a new one, inserting it with the power still applied.
There is a small chance there's not really something wrong with the drive, the data just got corrupted in a manner from whihc the NAS can't recover. You can use vender tools on a PC to test it before you replace it, if you so desire. If it's still under warranty, you'll likely need a code from the test to get an RMA, anyway.
I suppose the drive test built into the NAS would also point to the bad drive, but the method I gave above is typically faster.

Unfortunitely i have already tried booting into Volume read only and just booted into the same 'Checking system FS' as soon as it tries to boot.
I will see if any other suggestions come in then may need to resort to netgear support.
