I just installed OMV and have everything configured and working properly (I thought). I can access files from all my Windows devices. I can even write to the share - create folders, copy files & folders.
On my Linux box (Ubuntu Mint), I can see the folders & files and I can open them. However, when I try to copy files from my Mint box, I get "Permission Denied". I checked the settings for the OMV and the share is set to "Guest Allowed", the Read Only option is off, the Browseable is on.
I have no idea why I can read/write from the Windows machines (I tried 3 different ones), but not from Linux. I am using SMB/CIFS.
