TRAID and USB copy problems.

[Tricky]

Having set up my other F5-221 as TRAID i was intending to copy the contents of the RAID and single disks in the other F5-221 via USB copy onto the newly setup TRAID F5-221 and then once copied set up the other as TRAID however I have now run into a problem the RAID disk which is in a caddy and connected to the TRAID F5 is visible in the HDD list but is not mounted, is this because it's a RAID disk or is there something I am missing?

According to @claudiocarli post and the reply form admin, it can be done? viewtopic.php?f=87&t=3191&hilit=TRAID

Copy from one TNAS to another TNAS with USB Copy? How?

[Tricky]

Take a drive from one TNAS and put in a powered USB caddy, plug into the other TNAS USB port and hit USB copy, however as I said the drive shows up as connected in the disk menu but won't show in USB copy menu maybe because it's RAID perhaps?

Can you recommend a way to copy selected content from one machine to another that's reasonably quick? Other than copy and paste on a PC?

Your idea is feasible but there are significant difficulties.
The assemblage of RAID and subsequent storage preparation work are generally automatically executed after starting TNAS. When you directly connect RAID to USB, it cannot automatically assembe RAID and complete storage preparation work.
Although this process can be completed by restarting or manually assemblage, due to the possibility of conflicting storage configurations from two TNAS, we do not recommend doing so.

Have you considered rsync? Seems it was made for this type of process.

You can use Rsync backup or mount folders from one TNAS to another TNAS via SMB or NFS, then back up your data in folders with TFM.
