File number and/or size limits on volumes

There seems to be a limit to number and/or size of files in a docker volume? I used 30 k files with up to 400 kB in size and the volume doesn’t mount properly. when I reduce the file number to 10% or so it works like a charm. Any input appreciated…

Check your resource usage to ensure that it has enough number of the space to handle to volume.

Thank you @Raman004 . There is sufficient disk space and the program package runs like a charm on the same hardware without using docker.

What’s the underlaying file system?

How do you create the volume? Using which options?

The underlying FS is BTRFS.

volumes are created like
volumes:

  • ./data:/app/data
