No available storage pool for creating a new volume

I have Synology DS716+II, recently upgraded my HDD to 8TB - all in one storage pool using RAID 1 with data protection. And without paying much attention, a single volume takes up all the space.

I was able to upgrade to DSM 7.2 without any issue, but when it comes to the whole volume encryption, I am out of luck.

I have “no available storage pool for creating a new volume”, and “no drives are available for storage pool creation”. :face_with_raised_eyebrow:

Since I cannot shrink an existing volume, I am left with no choice but to back up my data and remove the current volume to start over again, is that right? :thinking:

Yes that is correct unfortunately

Thanks Will. Now I am know for certain, I will plan ahead next time when I upgrade.
