WARNING: This is risky. Just assume that you would only try this if you were ok losing your data.
When I got my first QNAP almost two years ago it didn’t support storage pools (or if it did I was oblivious). One of the advantage of storage pools is that they enable QNAPs snapshot replica feature. The trick is that you cannot migrate static volumes to storage pools, or so so says QNAP.
But it turns out there is a way to do this. Say you have a RAIDed static volume. There are at least two disks in such a volume, and you can withstand the loss of a single drive. You can “migrate” your data as follows:
- Shutdown NAS
- Remove all but one drive
- Power on NAS and wait for it to boot up. If you go to it (using QFinder for example) it will indicate that there are no disks.
- Insert a single drive (henceforth dubbed the “pool drive”)
- Choose “Restore to factory”
- Once it boots, delete the volume
- Use the deleted volume to create a storage pool and a new volume (I chose thin, because “why not”)
- Once the snapshot pool and vols are created, shutdown the NAS
- Remove the pool drive and insert the other drives
- Once the nas starts up restore to factory settings again.
- Once the factory reset is complete insert the pool drive again.
- You can now create shared folders on the storage pool, then rsync from the old static vol to the new storage pool.
The final step, once this is done (assuming you didnt lose any disks along the way!) you can expand the storage pool using the static vols, and viola, you’re back in action!
