'Out of space' MacOS error (code 100060) when moving files around on the same dataset

about 100GB of free space on the client. The share is pretty bog standard as far as the setup went. Default share parameters and no advanced settings as far as I can tell. Here’s what is checked off:

Access

  • Enable ACL
  • Browsable to Network Clients

Other Options

  • Enable Shadow Copies
  • Enable Alternate Data Streams
  • Enable SMB2/3 Durable Handles

All other options are unchecked.
