SMB broke in 13.2

the plot thickness, I created an external boot drive for the Mac Studio, with a 'scratch' volume. If I put an icon on the volume smb fails. If I remove it, and stop and restart file serving it works fine.

In my previous tests, I removed the icon from a drive I was trying to mount via SMB, but left the others as shared with their icons. After I am done with setting up the external boot drive and back on to the internal drive, I will remove all drives from sharing except one that will not have an icon and see if that works.

If that does "work" it will make things a bit harder for me as I have lots of external drives with icons representing what they are for. It has made my life easier, but I suppose I should be able to get along without the icons.

I just updated to 13.3, it is mostly fixed. The permissions (specifically write) still disappear for no reason, the work around with 13.3 is to unmount the drive from the client, then remount. No need to unmount on the server. At least that much is better.

Mounting seems to work fine. Overall, better, but not perfect.

I was finally able to test this great idea. It works fine. You are so correct about not making a mistake and trying to mount a volume. I did that at first. After a reboot, and this time selecting a folder to share, it worked just fine.

I put it in the apple feedback page. Who knows if that is ever looked at...

I have found a method of working around the permission issue. When the write perm from a shared volume on the client "disappears". If you dismount the drive from both systems, client and server. Then mount on the server and again on the client, the drive is again writeable, until it isn't again. Normally, I get several days between the mount/dismount cycle.

It works! If you remove ALL icons from ALL drives that have been shared, then they can be mounted by other systems. I blew away all the icons and now SMB sharing is "working" again.

I rebooted and all is well.

the only true workaround that anyone has posted is to go back to 13.1.

I ended up purchasing a couple of SSDs from OWC and installed 13.1 on them. Things are working for me since I did that.

More details on the write permission disappearing. It seems that instead of dismounting the share, one only needs to close the finder window, then open a new finder window for the same shared volume. Very odd...

Do you have an external drive to boot from? I did that and went back to 13.1 for my server system. It works, of sorts. Folders sometimes can not be deleted from the client system.

I have two ghastly workarounds, have a barf bag nearby ;-)

1. use screen sharing, you can drag and drop files between the windows.
2. I am able to mount windoze file systems on both, so copy from one Mac to windoze, then copy to other Mac.

I am still digging, but haven't figure out the issue yet.
