readynas 102 can't expand storage by adding a new hard drive

I have tried twice to install a new hard drive in bay 2 to expand my storage but the readynas does not automatically expand and go to raid 5 as it should. I have not changed x raid. The drive has been recongnised and synchronised but usuable space has not increased.

I then tried changing x raid to add a new volume to see if that changed anything but can not select new drive to add volume as it is greyed out.

 

Any suggestions as I'm stumped.

You need at least 3 disks to change to RAID-5.  With XRAID, the second disk converts the array to RAID-1.  That adds redundancy, but does not increase storage.

 

If you want to increase storage, you'd switch to flexraid.  The best approach is to then add the second disk as JBOD - creating a second volume that you can put new shares on. 

 

If your array is already RAID-1 (likely), then you'll need to create a new volume - you can't downgrade it back to jbod.  The simplest way to do that is do a factory reset with only one drive in place.  Then switch to flexraid after the NAS is set up.

Thanks Stephen, that worked. You know I couldn't find any information relating to that issue.

There are some knowledge-base articles and some info on RAID in the user manual (starting on page 22) here: http://www.downloads.netgear.com/files/GDC/READYNAS-100/READYNAS_OS_6_SM_EN.pdf

 

But lots of people do get surprised when they add a second disk and the available space doesn't increase.  Perhaps adding some specifics about that situation to the user manual and in this knowledge-base article would help.
