Remove inactive volumes to use the disk. Disk #1,2,3,4.

[bp75]

Had an error on drive 3, had it replaced.  Notice: data restored successfully.  Then got notice that drive 2 had errors. Went to investigate and now says: Remove inactive volumes to use the disk. Disk #1,2,3,4.

Please advise.

if it is booted and you can get to the system management page, go to system > settings > factory default

otherwise, you could do it from the boot menu, but that is a little more involved.

there is a recessed button on the back of the nas, you would need to power up while the button is pressed until you get the boot menu on the lcd screen, press the backup button to cycle through modes, press the button in the back to activate the selected mode.

if you have a device without lcd display, see also @ https://kb.netgear.com/22892/How-do-I-access-the-boot-menu-on-my-ReadyNAS-102-202-212-or-312?cid=wmt...

I have had this happen in the past, not sure what caused it.

Don't panic and don't remove any drives.

What I did was power off.

let it sit a few minutes

the powered back on and it worked normally without issue

if that doesn't bring the volume back up, you may need to wait for support to reply and/or open a support ticket with regular netgear support.

If you do get the volume back up and running, I would make sure you have good backup of any important data.

Nas/raid devices are not backups, backups are separate copies of your data on separate devices/locations.

Thanks for the reply.  No joy with reboot.  Fortunately I do have backups.  However, looking for direction on how to troubleshoot and either recreate, or start over with backups.

Can you send in the logs (see the Sending Logs link in my sig)?

[bp75]

Sent logs, thank you.

You should contact support if you want to purchase a data recovery contract for a data recovery attempt.

Thank you for your reply.  Can you help me understand what those logs mean.  I assume disk 3 that I replaced with a new one is good?? Or is that brand new disk bad as well.  Does 2/4 in the log mean 2 out of 4 disks failed?  Which disks?  Just replace disk 2 as well and I should be good?  Thanks again.

sounds like disk 2 might have failed at some point before the volume was fully resynced.

[bp75]

OK, I replaced disk 2 and i now get disk 2 greyed out and removed from the error which now reads: "Remove inactive volumes to use the disk. Disk #1,3,4."

How do I reset everything to make it useable and start fresh and copy my backups over to the drive.

Excellent, thanks for the reply.  I'm up and running again and recreating the data.  Really appreciate your time.  I know it's simple/obvious stuff for you guys but still appreciate you chiming in and helpin out.  All the best.

You're welcome!

Btw, you were very smart to make backups.

You might consider getting a 6 or 8 bay readynas if your storage needs grow, that way you can utilize dual redundancy and hopefully avoid any future scenario if a 2nd drive fails during a rebuild/resync.

You could then use your 4 bay nas as another backup destination using backup jobs and/or replicate.

The more copies of your data the better.
