No info what directory. I have tried multiple variants, but it doesn’t work.

How to fix this? Error message is not helpful.

How to make the right config config for NAS Synology? This imply data are already mirrored and also I don’t care about losing logs, because of hardware failure.

I have not setup Loki on Synology but when I installed Docker, I had to use the /volume1 directory as my root folder, so /data probably won’t work. if you long into DSM and go to the filestation, and create a data folder, it will be /volume1/data not /data.

Hope this helps!

Sorry for misleading. I added docker-compose.yaml context. This is not about /data/.

Any hints? I stuck on this.

Am seeing the same problem after upgrading my deployment on Kubernetes with the loki-distributed helm chart to 0.78.1. Everything but the compactor pod seems to be working fine. Was running the loki-distributed helm chart version 0.76.1 before this.

I was able to get things working again by adding this to the config:

compactor:
  working_directory: /var/loki/compactor
