Migrating from single disk to Raid 1
Hi all! Setting up my first Raid 1 NAS because I want redundancy for my important files. So here is my proposed plan.
1. I have a 3 TB drive with about 2 TB data on it - I'll call this the source disk. It has never been in an array, just a normal single disk. I purchase a D-Link DNS325 NAS which supports Raid 1 and has 2 drive bays. I also purchase a new 3 TB hard drive.
2. Install the new single drive into the NAS and set it up in Raid 1 mode.
3. Copy all files from source drive to the NAS which has 1 drive in it in Raid 1 mode.
4. Wipe the source drive and add it to the NAS and the Raid 1 array.
Does anyone know if that will work, and will the newest hard drive with all the data automatically mirror to the 2nd hard drive when it is added?
If the answer is NO, then my next question is what happens when 1 hard drive fails in the Raid 1 array and I need to replace it?
Thanks!
