At any moment, the SSD cache may contain data that has not been written to the storage pool. Normally when a user removes SSD cache, the system first moves any unwritten data in the SSD cache to the pool. However, when the pool is in read-only mode, the unwritten data cannot be moved to the pool, so to prevent data loss the system does not allow SSD cache removal.

If you want to remove the SSD cache, restore the storage pool to normal mode, so that any unwritten data in the SSD cache can be written to the pool before the SSD cache is removed.
