For the read only thing, this is normal and expected behavior for the pool.  SInce we can't be certain about the duplication levels of all of the files, we disable the ability to write to the pool, so that data doesn't get out of sync (corrupted).      However, the data dump causing the CloudDrive disks to get unmounted is definitely not normal.  If you could, enable drive tracing in StableBit CloudDrive, and reproduce the issue. http://wiki.covecube.com/StableBit_CloudDrive_Drive_Tracing
