Volume root is degraded

I would like to completely reconfigue my NAS unit after a Volume root is degraded message showing up after running diagnostics.

I'm only running 2 drives in this unit as JBOD no need for RAID as I have the same amount of drives on the PC.

I have already taken the drives out and tested them for errors but are OK.

What is the best way to do this? so I can simply add another drive at a later stage.

I would like one drive storing TV Shows and the other drive Movies, Video's, Documents etc.

Just to clarify this, the OS partition is always mirrored on all drives - so it is RAID-1, no matter what RAID mode you are using for your data volume.  That ensures that the NAS can boot from any disk.

I'd do a factory reset with one drive installed.  Switch to FlexRAID as soon as the NAS is set up.

 

Then hot-insert the second drive, select that disk on the volume tab, and create a second jbod volume. 

 

I suggest either erasing the second disk, or unformatting at in a PC before you insert it.  If you don't do that, the NAS will require you to format the drive the NAS before it lets you create the second volume.

There's no "best" way, but there are three options:

  1. use the web ui: system->settings->update has a "Perform Factory Default" control.
  2. use the boot menu: see pages 74-75 here: https://www.downloads.netgear.com/files/GDC/READYNAS-100/ReadyNAS_%20OS6_Desktop_HM_EN.pdf
  3. Remove the disks, and either erase them or un-partition them in a PC.  Reinstall disk(s) with the NAS powered down.  On power up, the NAS will do a factory install.

nas.jpgI removed the drive from the NAS and performed a factory reset on the single drive left in the NAS.

I un-partitioned the other drive in another PC and added (16TB) back to the NAS and it took awhile to resync, now I can not do anyhting with it, I would like to use it as a seprate drive.

The only thing I can do is toggle the X-RAID

Allowing the second disk to resync was a waste of time.  What you should have done is toggled X-RAID off before you added the disk back, and then created a second volume.

 

What you do now is:

  • toggle XRAID off
  • destroy the current volume (option is on the volume settings wheel).
  • create two new ones.
