I’m trying to run Time Machine backups to the Turris Omnia. I’ve managed to set up Samba 4 and can access shared seemingly without issue. I managed to get a first backup to complete, but now I can’t mount the volume any longer. The Mac is giving me a very generic error message, and logread shows me this:

Sep 14 21:17:58 emerson smbd[16361]: sys_disk_free: VFS disk_free failed. Error was : No error information
I can mount other shares without issue. I didn’t find a lot of information about this error. Any suggestions?

I need to limit the available size since I want to back up two machines to the same underlying btrfs filesystem.
