There is a process versus just “swapping the drives out”. If you do that, the NAS will still see that your “volumes” the same sizes as before even though you know the drives are larger. I have the PR2100 that I purchased with (2) 6 TB HD inside the unit.
Before you do anything else, I highly recommend that you navigate to your apps and turn off Plex so that noone is queuing the drive while you’re performing this.
- Open browser and login into your NAS.
- Click “Storage”.
- Make sure you have Auto Rebuild turned to “On”.
- Click “Change Raid Mode”.
- Select “Raid 1”
- Check the box labeled “Expand Capacity”, click “Next” and follow the instructions.
This entire process will take some time, so be patient! Took about 8 hours +/- to rebuild/expand the volumes for EACH drive.
It will tell you to start by swapping Volume 1 and it will start expanding the volume (and rebuilding it).
And yes, my data was intact through the entire process.
Hope this helps you and others!
