Add larger drives in a Raid1 environment

Hi all, my first post here, as I just got my DNS-323 this weekend.  I've done some basic tests to ensure that the Raid 1 recovery works properly.  One thing I noticed is that when adding a new drive, it allows you to specify how much of the volume should be dedicated to Raid 1 (the rest used as JBOD).  One question I have is whether I will be able to increase drive capacity without any hacks?  I would test myself, but I only have the two drives to work with.

If I remove one of the 750GB, and add a 1TB or larger in the future, I'm assuming it will maintain the 750GB Raid 1 volume, and the additional 250 GB will be JBOD.  If I then add a 2nd 1 TB, will I have the option to make all of this a 1TB Raid 1 volume without formatting everything?  If not, I'm guessing the easiest thing to do would remove both drives, replace with the 1TB drives and copy over from the old drives using a USB/SATA adapter and EXT2 IFS.  Again, for now I'm trying to do some of the workarounds without any mods to the box.

Any experience with this?  Thanks all for the help!

Re: Add larger drives in a Raid1 environment

It will stay at the smaller level, assuming that it formats the correct drive.  You will also lose all JBOD information.
