Retention setting not working (trying to set 15 days)

[VinothGox]

Hi, I’m trying to set Pyroscope data retention to 15 days, but it doesn’t seem to be working; old data is not getting deleted.
docker-compose.yml

version: "3.8"
services:
  pyroscope:
    image: pyroscope/pyroscope:latest
    container_name: pyroscopenewy
    ports:
      - "4042:4040"
    volumes:
      - /mnt/HC_Volume_102625473/pyroscopeData:/var/lib/pyroscope
      - /var/www/html/projects/docker/testpyroscope/pyroscope-config.yml:/etc/pyroscope/pyroscope-config.yml
    command: server --config /etc/pyroscope/pyroscope-config.yml 
    restart: always

pyroscope-config.yml

server:
  log-level: debug
  api-bind-addr: ":4040"
  retention: 360h  # 15 days
  storage-compression: true
  storage-compression-level: 6

storage:
  path: /var/lib/pyroscope
  max-samples: 10000000

Expected behavior:

• Data older than 15 days should be automatically deleted from /mnt/HC_Volume_102625473/pyroscopeData.
• Storage usage should decrease over time once older profiles are removed.

Actual behavior:

• Data older than 15 days is still present in /mnt/HC_Volume_102625473/pyroscopeData.
• Storage usage continues to grow without old data being cleaned up.

Pyroscope Verison: v0.37.2

Questions:

1. Is the server.retention parameter still supported in the latest Pyroscope version?
2. Does retention automatically delete old data, or do I need to run a manual cleanup job?
3. Could volume mounting or compression settings prevent retention from working?

Any guidance on getting 15-day retention working would be appreciated.
