I have the following configuration based on this tutorial:
- Read/write disk image (macOS Extended [Journaled]) created using Disk Utility called
Backup.imgwhich resides on a partition of an external drive; when using a USB connection with the external drive (and mounting the "host" partition), I am able to further mount the disk image and write to its volume.
- Samba server on another machine that I use to serve the partition/volume on which the disk image resides. I can access the samba server fine and can see the disk image perfectly intact.
When I mount the disk image (accessing it from Big Sur in Finder after using the "Go To Server" feature to connect to the samba server), I find that I am unable to write to the volume. Moreover, when I "Get Info" on the volume,
I am told that I can only read even though my user is allowed read/write.
thus, I think because of this, I am unable to successfully execute (per the tutorial instruction)
sudo tmutil setdestination /Volumes/MyVolume/
Why is this? I keep wanting to blame it on a permissions issue but then all the permissions look fine when I check them out.
