ReadyNAS Ultra 6 stuck at "ReadyNAS" after degraded mode / failed drive
My ReadyNAS Ultra 6, running 6.10.8 became inaccessible yesterday. I tried to log in via http and SSH. http was non responsive and SSH allowed me to log in but immediately kicked me out.
When I looked at the front of the unit i saw, "default: DEGRADED". disk 2 had an "X" through it. I checked with RAIDar and I could see the device. The note was, "Volume default: RAID Level 6, Not redundant; 13.9TB (96%) of 14.5TB used".
The unit was making a clicking noise. I left it for a few hours and then decided to reboot - probably a mistake, I now realize.
So right now, about 15 hours later, the machine is on with "ReadyNAS" displayed on the front, fans running full blast, and I cannot hear any disk activity. I can see a very small pinpoint sized white LED flashing next to the display.
I am not sure what to do next. I would like to recover the data on the drives if i can. Should I replace the failed drive with a new drive? Is the system running an fsck or similar on all 13TB? Should I just leave it?
I looked into creating a bootable USB but I only have MacOS, no Windows and that seems to be a requirement for the Intel-based recovery USB.
Thanks in advance for any advice.

I'd start by powering down the NAS, and removing all the disks. Label them by slot as you remove them.
Then power up, and see if you get the expected "no disks" status on the NAS LED screen.
Assuming you do, then I suggest re-inserting all the disks except disk 2 (NAS powered down), then power up. If the NAS boots, then download the full log zip from the logs page. Your post suggests that there might be another failed disk (RAID-6 has dual-redundancy). I can help you analyze the log zip if you can't sort it out.
If the volume mounts, then it would be wise to make a backup before doing anything else.
If the NAS fails to boot w/o disk 2, then I suggest that you power down and insert only disk 1 - leaving the other slots empty. The NAS should boot, but of course the volume can't be mounted.
Repeat this process with the other disks (putting them in their correct spot, with the other slots empty). Note which disks will boot, and which will not. Also, if you hear the clicking noise, then that will tell you that the disk in the NAS is one that has failed. Be careful to power down the NAS before swapping around the disks.
The idea here is to identify any failed disks that might be in the chassis.
Let us know the outcome, and we can then work out any next steps,
Thank you so much for your help!
Here's where I am:
- powered down via button on front and removed all drives
- system booted successfully but could not access admin page via http or login via SSH. I could see it via RAIDar and it reported status as "Healthy"; name was incorrect / random / default name
- powered down via button on front and replaced all but the previously-marked-as-bad drive
- system booted successfully but could not access admin page via http or login via SSH. I could see it via RAIDar and it reported status as "Volume default: RAID Level 6, Not redundant; 13.9TB (96%) of 14.5TB used" (ie same as yesterday before I started).
The volumes are now visible on my local computers. I think my next step should be to copy as much data off the NAS as I can while waiting for a replacement disk from Amazon? Or should I add the disk first?
...or something else?
Thanks again for your help...

Yes, that is exactly what you should do.
I'd start with files that not replaceable (family photos, videos, other personal documents).
