RN212 Disk 2: Volume Creation Failed

Hi,

 

I recently bought a RN212 and started with one Seagate Ironwolf 4T ST4000VN008, which should be supported. 

 

It started with no problems.

 

Alas, last week I bought the same disk: Seagate Ironwolf 4T ST4000VN008 for slot two.

Now, I only get to see a 'black disk' in my dashboard under Volumes and get errors when I want to activate the HD.

 

Like:

Volume Creation Failed

 

I do see this: Disk one marked Blue and has a green dot which indicates spare disk.

Blue is marked Raid 1

Disk two is black.

 

Does this mean: RAID1, it uses the second disk? which I don't believe it does...

 I tried to make it a Global spare disk but got this error:

 

All I want is to use Disk 2 as my back up disk...

 

What can I do?

 

Thanks for the help!

 

Michel

    That makes sense, since you can't test it in a PC.  I do suggest picking up a USB adapter/dock - the adapters are pretty inexpensive, and they are useful when you need to test a disk.

    Did you first turn off XRAID?  If not, the NAS was attempting to create a RAID1 from your two drives, and you would not have created a second volume for use as a backup (unless you believe RAID is backup).

     

    Did you do anything with the drive before putting it in the NAS (like format it on a PC)?  Did you hot insert the drive or do so with power off?  Is your desire to get RAID redundancy for your volume, or do you really want a separate volume for backup (which is not really the best way to do backup)?

     

    One possibility is that the drive is simply bad from the supplier, so testing with Seatools in a PC (via internal SATA connection or SATA to USB dock) is a good first step.  Also, see if your NAS complains about a degraded (which means non-redundant RAID) condition with the new drive removed.

      Hi Sandshark Sandshark

       

      I feel really dumb, I think i insert the disk hot, while the nas was still on and the xraid on.

       

      Can I still recover the disk?

        That does no damage, and in fact is what we normally recommend. Though since XRAID was on, the system should have created a RAID-1 array on the two disks.

         

        Can you download the log zip file, and then copy/paste the contents of mdstat.log into a reply?
