Switch from SHR-1 to JBOD for more storage

[Enquiries]

I have a DS220+ with 2 4TB hard drives on SHR-1 used for document storage and PMS with all the Sonarr, Radarr, etc. automation. I'm starting to run low on storage, most of which is just TV and movies.

I already have a 3-2-1 backup setup, and I don't feel like I need 100% uptime for business purposes so I'd like to switch from SHR-1 to JBOD to increase storage capacity.
Would doing the following work?

1. Pull one of the drives from my NAS so it degrades the volume
2. Connect that drive elsewhere and format it
3. Connect that drive via USB to my NAS, copy all the existing data in the storage volume to the externally connected drive
4. Delete the existing storage volume on the NAS (will DSM allow this while the volume is degraded or would I need to factory reset the whole thing?)
5. Create a new JBOD storage volume
6. Re-insert the drive I pulled at the beginning that now has the copied data

Aside from purchasing larger drives, is there a better approach to make this change?

Thanks!

Thank you for your question! You can achieve your goal of switching from SHR-1 to JBOD while ensuring your data remains safe during the process. Here's the approach I recommend:

Remove One Drive: Start by removing one of the drives from your DS220+. This will degrade the existing SHR-1 pool but your data will remain accessible on the other drive.

Connect the Removed Drive via USB Dock: Use a USB dock to connect the removed drive to your NAS or a computer. Check if the data is accessible from this drive. If you can access your files, it confirms that your data is intact on the removed drive.

Delete the Existing Storage Pool: Once you’ve verified the data, DSM will allow you to delete the degraded SHR-1 pool with the remaining drive. You won’t need to factory reset your NAS; simply go to the Storage Manager in DSM to delete the pool.

Create a New JBOD Pool: After deleting the existing pool, insert both drives back into the NAS and configure them in JBOD mode.

Copy Data Back: Connect the drive in the USB dock back to your NAS and copy your data into the new JBOD volume using DSM’s File Station or a backup app.
