Problems with data import using SharePath

[DP1701]

Hello,

I have spent hours trying to achieve the following on macOS. Install CVAT and configure it so that data can be imported with a SharePath. However, the data should then be stored on an external hard disk. This is my docker-compose.override.yml:

services:
  cvat_server:
    volumes:
      - cvat_share:/home/django/share:ro
  cvat_worker_import:
    volumes:
      - cvat_share:/home/django/share:ro
  cvat_worker_export:
    volumes:
      - cvat_share:/home/django/share:ro
  cvat_worker_annotation:
    volumes:
      - cvat_share:/home/django/share:ro
  cvat_worker_chunks:
    volumes:
      - cvat_share:/home/django/share:ro

volumes:
  cvat_share:
    driver_opts:
      type: none
      device: /Volumes/Data4TB/CVAT/SHARE
      o: bind

I have changed this in docker-compose.yml:

volumes:
  cvat_db:
  cvat_data:
    driver_opts:
      type: none
      device: /Volumes/Data4TB/CVAT/DATA
      o: bind
  cvat_keys:
  cvat_logs:
  cvat_inmem_db:
  cvat_events_db:
  cvat_cache_db:

Now comes the strange behavior. If I do not run the following command in the terminal beforehand, CVAT does not show the SharePath folder when a new task is created.

find /Volumes/Data4TB/CVAT/SHARE \( -name '._*' -o -name '.DS_Store' \) -delete

It removes the metadata in the folder. But even if I then select the folder and choose the option “Copy data into CVAT”, I get the following error message in the console:

When copying the images to the Data folder, there seem to be problems with the metadata being recreated. Does anyone have a solution to this problem?

macOS 15.3.1
CVAT v2.32.1

I have found the reason and the solution. The external hard disk should be formatted to either APFS or HFS+. If it is exFAT or FAT, then macOS creates the metadata on these file systems alongside the original files, as it is needed for the Finder, tags, Spotlight and other things. Under APFS/HFS+ this information is also created, but stored differently and linked to the file. In any case, I no longer have these problems.
