Replication Error "cannot unmount'

[jspfunk]

I just set up my Dell Precision T7910 and I am trying to replicate the data from my current Server, but I keep getting this error.

Code:

"[EFAULT] cannot unmount '/mnt/Plex/Media': pool or dataset is busy." 

I have tried running the replication from both machines, but I get basically the same error.

I am a noob mostly, and I did searches for the error, but I couldn't really find anything that helped.

Here is the log file:

Could someone give me an Idea of what to look for?
