Tip: Install Midnight Commander (MC) on your Rockstor host for fast local file copy/move.
In the System Shell for via SSH:
# zypper install mc
For reference: I am running Rockstor 5.1.0-0
MC has a Text User Interface (TUI) that will allow transfer of files (copy/move) locally on your Rockstor host.
This is beneficial for moving large files between storage arrays. When you move files with your laptop or desktop (via wired or wireless) the file moves are processed “through” your PC and take much longer to transfer.
Before Rockstor, I had a QNAP TS-453 Pro with three external QNAP TR-004 [ https://www.qnap.com/en/product/tr-004 ] expansion units.
The units are fully populated with drives and at the time, seemed like a low level of effort to expand my current NAS storage.
My QNAP TS-453 died and a replacement QNAP software had changed to where I would need professional services to import the previous data and reformat the TR-004 expansion units. So I replaced the TS-453 with a Mini PC (Newsmay AC8) and plugged in the three TR-004 expansion units (via USB 3.0) — been using Rockstor ever since and it has been rock solid. I am a paid subscriber to Rockstor as it runs great on this low spec mini PC. I will never buy a proprietary NAS again.
Using MC I was able to move files between the RAID groups on each of the expansion units at about 10x speed. The same functions can be done via the command line, but MC gives just enough of a text menu to make this easier and faster.
Caveat: You may have to re-adjust your permissions if they differ. You can do this at the command line (e.g. chmod) or use the GUI. For example, in my case I am using SAMBA shares, so navigate to Storage > Samba > Access Control > Edit > Apply
