Data: DEGRADED on RN104
Hi guys, extreme help required. Added a second 4TB WD RED into slot 2 of my RN104 NAS tonight and everything started off ok and then suddenly I have the following flashing at me every few seconds.. ...
Sent you a PM
I'm in the process of upgrading the original 1TB toshiba disks in my ReadyNAS 104. Following this thread closely.
I have just replaced (10 hours ago) the toshiba drive in Channel 2 with an on-the-list compatible Seagate 3TB disk.
What should the message window display during the rebuilding time?
It continues to display "Data Degraded"
From a UI standpoinrt, I would have thought it, or the admin console, or RAIDar, or ??? would have given some message indicating that the volume was "rebuilding."
Or, is something not working? I.e., I can't find any reference in the forum, nor documentation, nor videos on youtube, what indicator should be presented so I don't just think it's hung in a bad state.
Is it ok that it continues to just say "Data Degraded," and regardless of the message, it is rebuilding?
[Since this is a current thread, on this topic, and would be interesting to the next person looking for what the UI and user experience should be telling them..., I found it logical to ask it here. Moderators, please move and add context, if this is the wrong place. Apologies in advance.]

We prefer new threads for each problem, otherwise the advice/responses get tangled.
Did you insert the new disk unformatted? What firmware are you running?
Thank you StephenB. Apologies for not starting a new thread. If moderators move it (I don't know how.) I'll go there. In the future, I'll start a new thread.
I put the new disk in, just over 48 hours ago. It is still displaying "degraded." Should rebuilding from a 1TB to a 3TB disk take over 48 hours? That seems excessive in my experience with other RAID systems I have.
Just after I put the newe 3TB Seagate disk in, I opened the console, and it said a firmware update was available. I had just updated to 6.2.4 a couple of months ago - or I would have checked this. I downloaded the new 6.2.5 firmware, but did not reboot the system since I assumed that not to be prudent. So, based on the console, I am running 6.2.4.
I figured rebooting, in the middle of a rebuild - which everwhere I read said began immediately after inserting a new disk. So, even with the message "Degraded" flashing on the display, I just let it go on doing what all indications seemed to say it was "rebuilding" the volume. I could not find any documentation or threads that indicated yay or nay to reboot undert these conditions. Being cautious, I let the perceived rebuild go on..., but after 48 hours, I think something has failed.
Basing a conclusion on my obsevations, I assume that NetGear does not display a meaningful message of "Rebuilding" after a hot-swap. And, that "Degraded" is the message it displays until the rebuild is complete? Can anyone confirm this?
0utside of that: user friendly indicator messages on the Wishlist Request for next version of software, please!
Thank you to anyone that can give me guidance on how to get this back to normal operation. I have a second 3TB disk to put in Channel 1, replacing the other original factory Toshiba 1TB drive. But I'm savvy enough to know not to put that disk in until after the rebuild is complete on the first drive replacement, in Channel 2 (above - which is still reporting "Degraded".
As I think about this - is the system in limbo, pending the reboot to load the firmware? And, if I reboot, will that new firmware gracefully handle the new disk? I assume it will have to "infer" that it is new (as X-Raid docs I read elsewhere say it will) which will be an even longer step. I was relying on the software to "see" the hot-swap, and be more expeditious in the rebuild.
Thank you to all the great minds here on this forum that can help me. If I screwed up, I'm a big boy, and can take it. I just need to know what I did, so I can learn not to do it ever again.
Summary questions:
- How long should it take to rebuild from a 1TB to a 3TB disk? Less ormore than 48 hours?
- If the firmware is updated after a disk hot-swap, is the system in limbo, waiting for the reboot, before it will complete the rebuild?
- Ergo, should I reboot the system? The Admin Console keeps prompting me to do so.
- And, of course, what "message" should display on the screen during a rebuild? "Degraded" or something more meaningful?
- Bonus Question: Is there an index/glossary of all the poential screen messages possible for a DN 104? I didn't see anything in the documentation online.
Thank you,
AndrewJohn
In the interest of completeness, here are three pictures of my Admin Console. The first shows the "reboot now" to use the new firmware, message, and the current firmware version. The second shows the arrangement of the volumes and drives installed. The third shows that if I select the new drive, the "FORMAT" button becomes active. Which is wierd. All things I have read indicate that a new drive will be automatically "managed" including formatting, upon inserting it into the channel. To be sure, this is a brand-new, in the original packaging and box, NOT a reused drive. I buy drives by the case - and this is one more of several I have in that lot. I've not had a problem with any other drives in the lot.
