mkdir: cannot create directory ‘/var/lib/postgresql/18’: Permission denied

❓Question☑️Ready

I previously had a working immich setup as an app on Truenas, but now the app won't start correctly with the

pgvecto

pgvecto

container exiting immediatly with the log line

 mkdir: cannot create directory ‘/var/lib/postgresql/18’: Permission denied

 mkdir: cannot create directory ‘/var/lib/postgresql/18’: Permission denied

. Looking at the volume mounts,

/var/lib/postgresql

/var/lib/postgresql

maps to

/mnt/all_storage/immich/pgData

/mnt/all_storage/immich/pgData

. That dataset pgData is owned by

netdata

netdata

and the owner of that dataset has full read and write permissions, as specified in the Truneas immich setup documentation (http://docs.immich.app/install/truenas/#setting-up-storage-datasets). I've attached images of what that Truenas configuration looks like. How can I debug what's going wrong and resolve this?

I'm on version 1.11.4. I've tried upgrading to 1.13.6 but that hasn't sovled the issue.

Information requeted in other tickets:
- Your docker-compose.yml and .env files: This is handled for me by the Truenas app and I don't know how to access them
- Logs from all the containers. pgVecto just repeats

- All the troubleshooting steps you've tried so far: try many restarts and upgrading immich
- Any recent changes you've made to Immich or your system: no changes
- Details about your system (both software/OS and hardware): Truenas
- Details about your storage (filesystems, type of disks, output of commands like fdisk -l and df -h). Truenas datasets setup as directed by guide: http://docs.immich.app/install/truenas/#setting-up-storage-datasets)
- The version of the Immich server, mobile app, and other relevant pieces: 1.11.4
