Amanda and OMV

I have two PIs.
On one of PI I have OH and on the second OMV (openmediavault).
I would like to use OMV as a NAS that will store backup copies from first PI.
NFS shared folder is mounted. The problem is that I can’t setup correct permissions to install Amanda (installation is aborted).
Below you can see details of Amanda installation process:

2020-12-14_08:52:30_CET [openHABian] We hope you got what you came for! See you again soon :wink:

I’m not sure if it is a problem with OH or OMV configuration.

Thanks for any help!

It’s probably a user client-side problem (but not OH/openHABian because you do that part yourself manually) to mount the share with the proper options to map root UID. See Amanda README.


Thanks a lot!

The problem was that option no_root_squash was not setup for NAS.

Now everything works ok
