"Too many open files in system error" during library scan

[awkward-gopher]

Well, I did something absolutely wacky, and it worked.

Here's how it breaks down: SMB support on Mac OS is just really unstable. I couldn't actually get it working using that. Instead, I baked a new container. I'll provide the dockerfile and entrypoint for reference if anyone is interested. But, with these changes, it mounts the SMB mount *within* the container, instead of mounting it in Mac OS and accessing it via a docker volume.

Here's how it works:

Added a new Dockerfile:

Code:

FROM jellyfin/jellyfin:latest

# Install CIFS utilities for mounting SMB shares
RUN apt-get update && \
    apt-get install -y cifs-utils && \
    apt-get clean

# Copy custom entrypoint script
COPY entrypoint.sh /entrypoint.sh
RUN chmod +x /entrypoint.sh

# Override entrypoint
ENTRYPOINT ["/entrypoint.sh"]

And the entrypoint

Code:

#!/bin/bash

set -e

# Ensure required env vars are set
if [[ -z "$SMB_SERVER" || -z "$SMB_SHARE" || -z "$SMB_USER" || -z "$SMB_PASS" ]]; then
echo "Missing SMB environment variables! Exiting."
exit 1
fi

# Define mount point
MOUNT_POINT="/data"

# Create mount directory if it doesn’t exist
mkdir -p "$MOUNT_POINT"

# Attempt to mount SMB share
echo "Mounting SMB share: //$SMB_SERVER/$SMB_SHARE at $MOUNT_POINT..."
mount -t cifs "//$SMB_SERVER/$SMB_SHARE" "$MOUNT_POINT" \
-o username="$SMB_USER",password="$SMB_PASS",vers=3.0,uid=1000,gid=1000,iocharset=utf8,rw

# Ensure mount is successful
if ! mountpoint -q "$MOUNT_POINT"; then
echo "Failed to mount SMB share! Exiting."
exit 1
fi

echo "SMB share mounted successfully."

# Run the default Jellyfin entrypoint
exec /jellyfin/jellyfin

And an update to the compose service

Code:

  jellyfin:
    container_name: jellyfin
    build:
      context: .
      dockerfile: Dockerfile
    privileged: true
    cap_add:
      - SYS_ADMIN
      - DAC_READ_SEARCH
    devices:
      - /dev/fuse
    tmpfs:
      - /run
      - /tmp
    network_mode: host
    restart: unless-stopped
    volumes:
      - ./jellyfin-config:/config
    ports:
      - "8096:8096"
    environment:
      PUID: 1000
      PGID: 1000
      TZ: America/Los_Angeles
      SMB_SERVER: my-server-name
      SMB_SHARE: jellyfin
      SMB_USER: username
      SMB_PASS: password

By doing this, everything works and I'm able to scan the library. I think it might be a bit snappier as well. But that's not measured, just a feeling.
