I'm trying to edit (with vim) the /etc/samba/smb-names.conf, to enable the archive bit, changing the map archive setting to Yes.

Just after saving, with 'cat' I can see the change, but after a while, the change is reverted.

 

¿ How have I to edit this file ? ¿Why, and with what mechanism is preserving this file? Thanks

As I recall, this original of file is actually inside of the compressed image and gets reloaded each time unRAID is restarted.  So your edits are being lost. 

 

Look inside of smb-names.conf.  I seem to recall that it loads another file that you can create and save on the unRAID USB drive.  Put your changes into that file.

 

If that doesn't work, save your edited smb-names.conf to the USB drive and modify the 'go' file to stop SMB, copy your edited file into the correct location (/etc/samba/) and restart SMB. 

Thanks Frank, maybe thay's the key.

It calls another file, smb-extra.conf, in /boot/config. I`ve created this file and I think it's working
