I know this is a common problem and it should be easy to fix but I've spent the last hour trying to understand what I'm doing wrong.
I just set up OMV on a Raspi4. An external USB hard drive exFat formatted is mounted and then activated as share. I can see the share and read files from it from both Mac and Windows in the LAN.
However, I do not get any write permissions (tried on both Windows and Mac OS): whenever I try to write I get a message saying that only root has write permissions?!
I created specifically a new user (sambauser), which I'm using to log in to the share, that has read/write permission on the share.
I rebooted both the host and the server multiple times without luck... Can anyone tell me what I'm doing wrong?
I don't know if it's relevant or not but I cannot save anything in the ACL tab.
