Storage spaces low capacity while drives are half full

Ok I've researched and seen this but no real answer other than start over. Have a mirrored refs storage pool on win 10 pro. Pool was created with 2 6tb drives and then 2 8tb drives were added. This all before any data was actually written to them. That was last year. No failures or hiccups until now. Server is accessed remotely and not always looked after but getting a low capacity warning to add 2 drives and shows all 4 drives are 99.99 percent full. I over provisioned the pool originally to 24tb for future expansion. With 14tb of actual storage it's not even using 7tb yet. Optimization will not run for the gui. Running in powershell it kicks out that the volume is too full. System restore past last major update did nothing and system restore was checked to make sure that the mirrored drive was not listed causing mirrored snapshots. ![74581-img-20210303-053648.jpg][1]![74591-img-20210303-053355.jpg][2] [1]: /api/attachments/74581-img-20210303-053648.jpg?platform=QnA [2]: /api/attachments/74591-img-20210303-053355.jpg?platform=QnA

    Well I thought I would get a little more input on this but maybe I'm the only one that plays with storage spaces. Have a backup drive on the way to rebuild my storage. Still going to use storage spaces but provisioning will be set to fixed this time. The one thing I wondered is why a storage spaces is defaulted to thin. Whatever drives I would want to use for mass storage I'm trying to use whatever space I can get. I understand setting thin provisioning for vms because you can set many to one drive. So anyways new setup. Mirrored refs fixed provisioning. Hopefully good to go.
