ReadyNAS Ultra 4 "Volume data is degraded"
Hello everyone,
Hope someone can help me with the best course of action for my problem. Yesterday night I got a message from my Ultra 4 saying my Volume is degraded. When I accessed the ReadyNAS webpage and went to the logs I saw this "Disk: Disk in channel 1 (Internal) changed state from ONLINE to FAILED." and I'm assuming it died. Before I replace it with a new one I'm gonna plug it into my computer and run a few tests to see if the issue is true with the HDD. Let's say it is and I need to replace it and that's the questions I have.
1 - Can I continue to use my NAS as usual until I replace it next week? Originally I have 4x 8TB Ironwolf drives on it. Should I leave the "failed" HDD in there for now or should/can I remove the drive and leave the NAS with the remaining 3 HDDs which show as Healthy for now?
2 - I'm getting another 8 TB but I want to know if the ideal would be to replace it with the same HDD brand, size, and model or just the size matters?
3 - After replacing the HDD is there any action I need to do from my end or it will resync automatically? My 4x 8 TB setup is X-RAID. If someone can explain in detail the procedure/process to replace will be super appreciated.
Thanks again in advance for any help and or comments

You can continue to use it - however if a second disk fails, then you will lose all your data. If you don't have a current backup, you should update it (at least copying off irreplacable files).
You might as well remove the disk (with the NAS running).

I run the full long test, followed by the full erase test - because I have had some new drives that passed one of those, and failed the other.
Whether you do that or not, the procedure is to remove the old drive and insert the new one. I always recommend doing both steps with the NAS running.
