Convert a Single-Volume Storage Pool to a Multiple-Volume Storage Pool
You can add drives to a storage pool and convert the storage pool from one that supports only a single volume to one that supports multiple volumes, without affecting the original data on the volume.
Before you start:
- This feature is supported on a single-volume storage pool in SHR configuration only. SHR (Synology Hybrid RAID) is available on specific models only. Please refer to this article to find out if your model has limited support for SHR.
- The capacity of a storage pool must be expanded first, thereby allowing new volumes to be created on the storage pool. Please refer to Add Drives to Expand the Storage Pool Capacity for instructions.
- We recommend using drives in the Synology Products Compatibility List to prevent any issues. Using incompatible drives may lower the system performance and even result in data loss.
To convert a single-volume storage pool to a multiple-volume storage pool:
- Launch Storage Manager.
- Go to Storage Pool.
- Click Action > Convert a Single-Volume Storage Pool to a Multiple-Volume Storage Pool.
- Follow the wizard to finish.
Note:
- The Convert a Single-Volume Storage Pool to a Multiple-Volume Storage Pool option only appears when the single-volume storage pool is in SHR configuration, and when there are additional drives installed in your DiskStation.
- The number of added drives must increase the storage pool size; otherwise, you will not be able to perform the conversion.
- The Convert a Single-Volume Storage Pool to a Multiple-Volume Storage Pool option will become disabled if the single-volume storage pool is in SHR configuration, but the storage pool is in Abnormal status.
