Readynas RN314 Degraded problem
Hello i have a READYNAS RN314 "DEGRADED" message that i need help with. I looked online but cannot seem to find what to do about this so hopefully someone can help.. Any help is much appreciated! ...
Hi, Thanks for the quick reply.
I had a look at the logs but they dont record any errors. I cant seem to find where it tells me this drive failed. Other than the diagram on teh overview page, and after it failed to resync...(see below)
----
I note you are saying the referencing goes Channel 0 = 1st on left, and Channel 3 = last on right.
However the message i got now is:
Disk in channel 3 (internal) changed state from RESYNC to FAILED
In the diagram disk 3 of 4 ie 3rd from left is highlighted as teh problem drive (not last disk as suggested in your post).
Also the third one light was flashing on and off, while others are constant green. So figured its that one.
So i removed the drive, to see if its still under warranty and check. Turns out it isnt by a few months.! Pretty annoying. WD Nas Red 6TB!
Logs now say the disk was removed from Channel 3 of the head unit
Have ordered a new drive.
Can i just insert once received and it will format and resync data automatically?
Or do i need to format?
Thanks
Thank you for the information you provided. It seems that the GUI is showing the disk bays as channels 1 to 4 instead of the one I mentioned (Channels 0 to 3). My apologies for the mix up but it's still good that the failed drive was removed and will be replaced.
Yes you can insert the drive once you have it and it should automatically resync with the array. The formatting will only be done if it's a used disk or previously formatted drive.

Yes, it's best not to format it.
I do recommend
- testing the drive in a Windows PC (with lifeguard or seatools) before you hot-insert it. I run both the extended test and the destructive "erase disk" (or "write zeros") test myself.
- Backing up your data! RAID isn't enough to keep your data safe - so you should have a backup plan in place anyway. But your data is more vulnerable than usual when the array is degraded - and it's most vulnerable when you are adding a new disk.
- Using a NAS-purposed or enterprise class disk. Personally I use NAS-purposed - but if you have 7200 rpm drives in now, it might be better to go with enterprise-class.
Also there are some maintenance tasks that you can run on demand or schedule on the volume tab. These include a disk test. Personally I run each of those tasks once every three months on my own NAS - one reason is that can give me earlier warning that a disk is starting to fail.
Thanks for the replies, yes we have a backup.
Regarding testing is there a way to auto schedule these disk tests from teh volume tab - it seems to just do it on clicking?
Is it better to insert the new drive when the nas is powered down, or insert when power is on, or does it not matter? Many thanks
Scheduled testing is enabled under the "Volume Schedule" options. I always recommend hot insertion of new drives (and hot removal if replacing one), as one can then see in the log that the NAS recognized the action.
