I have tried mounting both "cachedev_1" and "/dev/vg1/volume1", but it always says that it's "already mounted or mount point busy". I tried the command for unmounting and shutting down all service except SSH (forgot the exact command), but it doesn't exist in DSM 7, and I couldn't find an alternative. Thanks for the idea! I had tried that previously, with one big issue; I only have the 12 drives on the LSI controller, so passthrough'ing that would make me lose my ESXi datastores which hosts the SynoBoot. I'll try and see if I can get another drive in there to act as datastore. If so, I'll go by your recommendation. Thanks again! Thanks for the idea!
