I've got a Synology 2-bay NAS (DS213). Initially I added a single 3 TB disk. It was configured with SHR (with no data protection). I have some data in it too.

Now I've got a new disk, and have added it into the 2nd bay.

Is it possible to add this new drive into the same Volume?

My goal is to ensure that data protection can be enabled.

When I open the DSM Storage Manager application, the Manage button is disabled for the volume.

How can I add the new disk to the existing volume?

I guess it is not possible. I had to take backup of the data to a external USB drive, and then recreate the volume using both the harddisks. And then copy back the data into the new volume.
Now its working fine.

I know you found a solution, but in case others read this, they should know that it ought to be possible to expand the existing volume (or disk group) - see this Synology tutorial for the details: http://www.synology.com/en-global/support/tutorials/559

In particular beware that the new disk you add to the volume has be at least the same size as the existing disk in your volume - otherwise you will not be allowed to expand your existing volume.
