I am running telegran 1.20.4 in docker (with grafana, influxdb) in a system with OpenMediaVault 6 (Debian).
I have installed hd-idle to manage when my disks should spin down when they are not in use.
I had one disk that was unable to spin down and after a lot of try and failure I found out that was telegraf container who prevented to spin down. As soon I as I stop the container, the disk goes to sleep.
This is my telegraf docker-compose:
telegraf: container_name: telegraf restart: unless-stopped volumes: - /docker/telegraf:/etc/telegraf:ro - /proc:/host/proc:ro - /:/hostfs:ro - /var/run/docker.sock:/var/run/docker.sock environment: - TZ=Europe/Madrid - HOST_MOUNT_PREFIX=/hostfs - HOST_PROC=/host/proc network_mode: host image: telegraf:1.20.4
I tried to remove HOST_MOUNT_PREFIX and HOST_PROC with no success.
This is my telegraf config file:
[global_tags] [agent] interval = "10s" round_interval = true metric_batch_size = 1000 metric_buffer_limit = 10000 collection_jitter = "0s" flush_interval = "10s" flush_jitter = "0s" precision = "" hostname = "" omit_hostname = false [[outputs.influxdb_v2]] urls = token = bucket = [[inputs.cpu]] percpu = true totalcpu = true collect_cpu_time = false report_active = false [[inputs.disk]] ignore_fs = ["tmpfs", "devtmpfs", "devfs"] [[inputs.io]] [[inputs.mem]] [[inputs.net]] [[inputs.system]] [[inputs.swap]] [[inputs.netstat]] [[inputs.processes]] [[inputs.kernel]] [[inputs.hddtemp]] [[inputs.docker]] endpoint = "unix:///var/run/docker.sock" gather_services = false container_name_include =  container_name_exclude =  timeout = "30s" docker_label_include =  docker_label_exclude =  perdevice = true total = false
I tried to remove [[inputs.disk]] and [[inputs.io]] with no success.
If the disk is sleeping and I start the container, nothing happens. But, if the disk start spinning when the container is running, then it won’t stop spinning again.
I have four disks and only happens in one of them. No idea what to try more. Any help?
