So I updated to Firmware 6.9.4 the other night, I turned the nas off yesterday afternoon and restarted it this morning to be greeted with "Remove inactive volumes to use the disk. Disk #1,2,3,4." Currently running x4 4TB harddrives in a Raid 5.
Below is a copy of the system log, all hard drives appear to be in 'good health' and weren't showing any issues relating to performance etc.
Sep 19, 2018 10:19:40 AM System: The system is rebooting.

Sep 18, 2018 08:12:42 PM Disk: System will be shut down in 30 minutes because of disk failure.
Sep 18, 2018 08:12:42 PM Volume: Volume data health changed from Degraded to Dead.
Sep 18, 2018 07:55:32 PM Volume: Resyncing started for Volume data.
Sep 18, 2018 07:53:32 PM System: ReadyNASOS background service started.
Sep 18, 2018 07:53:08 PM Volume: Volume data is Degraded.
Sep 18, 2018 07:53:07 PM System: Alert message failed to send.
Any issues what would've caused this / if the volume and data are lost for good?
Thanks for that, I hadn't replaced any disk taken anything out for that matter.
So it's possibly down to a drive failure? If so, do I have to have replacement disks ready? (I have none atm) The drive is still under warranty though, it also says it's healthy on raidar
Are the drives bundled with the NAS? or they still have warranty with the Manufacturer? I would advised claiming warranty from the Manufacturer or NETGEAR if this is the case.
You will have to ready your replacement once this is handled by L3 experts, The lost of volume data is from the drive failure and not the upgrade itself.
RAIDar might be showing healthy disks but what needs to be done is to have your RAID mounted so you can access Data. I do think that only Disk on Ch4 is the only one needing replacement.
Base on the logs you posted, your disks failed after the update. Were you having warnings before the update regarding your disks status? Losing the volume might be of multiple disk failure or another issue.
You may want to check if you can still download the full logs and see disk_info, volume, kernel and systemd-journal
Data might still be intact but that would need a Recovery service (You can contact NETGEAR Support for the service or a 3rd party recovery service).
Checking on the logs, the update pushed through last Sept 16 [18/09/16 19:33:08 WEST] notice:system:LOGMSG_FIRMWARE_UPGRADED Firmware was upgraded to 6.9.4.
The possible cause would be disk on Ch 3 is resyncing and Ch 4 failed rendering your Data volume dead.

Have you replaced Disk on Channel 3? Under Smart history your disk on Channel 4 was already getting errors (Pending Sector)
The best action right now is to contact NETGEAR Support and ask for L3 assistance for Data recovery. Have replacement disks ready as well. You can login to my.netgear.com and create a case so it can be prioritized.

The drivers and nas were purchased from a retailer in 2014. All purchased at same time from Scan UK.
All of the devices were registered, the Western Digital drives are still under warranty. The nas is showing as still under warranty (however it wont show under my account as registered, then when I register a new device it says already registered).
Correct me if I'm wrong, so after the firmware update the drives resync and I'm guessing this can take a while? The drives were still resyncing and then possibly Ch4 failed which caused the issue?
Does Raid 5 not prevent from this happening, I'm naive so please excuse me.

With RAID-5, there is no redundancy during a resync - the resync operation was rebuilding drive 3 from the remaining (the same way it does when a drive is replaced). So there was no protection when drive 4 failed during that resync - and the volume fails.
Could it be result of a sudden loss of power (we had storms)? I didn't think we lost power but I was off site.
That could be it. If the NAS shut down with cached writes that never got written then the system might do a resync. There are counters on each drive maintained by mdadm (the program that does the software RAID), so it will detect lost writes.
Unfortunately it's not protected by a UPS which I do regret in hinds sight. I suspect it may be a result of loss of power, and the drive log did say something referencing pending sector count.
