Failed to process the path: Input/output error

I use duplicati as docker on unraid. Today i connected a new 10TB harddrive nfts formated and made a succesful backup. When i try to create a second backup i get the error “Failed to process the path: Input/output error” while choosing the backup desination (the new 10TB drive). What can be the reason?

About all I can say as a Duplicati specific answer is:

If it keeps happening, try About → Show log → Live → Warning and click on the error to look at details.

Your OS logs might also say something somewhere, however it’s also conceivable nothing will go deep.

The problem was, that i unplugged one USB that was already listed as mouting point. After cleaning the old mouning points, everything works fine.
