Maybe this feature is already in front of me, but I could not find it. I have setup 3x HDD in SnapRAID (no pariry yet) and mergeFS system, I would like to know how can I transfer files between disk. I am in a situation where I need to replace a temporary HDD with a permanent one. I just want to empty the HDD and swap it with a new HDD and put the new HDD as part of the SnapRAID/mergeFS system.
Thanks
