hAP AX3 slow SMB transfers with MacOS and Apple TV

Is ROSE intended to be a full replacement of IP/SMB?

I’m trying to use it but…

[____@____] /disk> set usb1 smb-export=yes
failure: could not unmount filesystem - probably somebody still uses it

yes, disk is in use and should continue to be accessible by ROS for user manager, dude, logs, containers…

I want to share (some folder of) the disk by SMB over the network, not make the usb disk usable only from the network.
