ReadyNas NV+ Expansion for Dummies
Help! I am not an IT guru so please be patient with me...I can't seem to find a manual or info on adding a 3rd & 4th drive to my NV+ that is already set up (2) 500 MB drives. I am using my ReadyNAS ...

Thanks. You are running XRAID, so drive 1 and drive 2 are in a RAID-1 array.
-To get the configuration you want (Drive 1/Drive 2 as one mirrored 500GB pair, Drive 3/Drive 4 as a second mirrored 1000 GB pair) you will need to start over with a factory reset, and switch to flexraid. You'd lose all your data and configuration - so you'd need to do full backup first, and then restore from the backup after the reset.
-The path you are on will expand your system to use RAID-5 with 4x500GB volume. This would have 1.5 TB of space (the same amount of as the configuration you want). There would be 500 GB of unused space on each of the new drives. If later on you replaced drive1 and 2 (one at a time) with 1 TB models, your system would expand to RAID-5 4x1000 GB( 3 TB space total). This is not mirrored, but you would have protection against any single drive failure.
I am not sure why your system hasn't already added the two new drives to your existing array. Wait for the resync to complete, and then report back on your array status.
I suggest you think through whether RAID-5 is acceptable, or if you really want the two mirrored pairs, and also post that info. Then we can outline how to get there.
