When deploying the Thanos Store container image in the k8s environment, can multiple replicas share the --data-dir=/thanos-store-data directory?

Hello, everyone!

When deploying the Thanos Store container image in the k8s environment, can multiple replicas share the --data-dir=/thanos-store-data directory?

When deploying the Thanos Compact container image in the k8s environment, can multiple replicas share the --data-dir=/thanos-compact-data directory?

Hey! I think not but I would need to check. Overall it's best not to share that directory. Perhaps we should implement some kind of locking in Thanos Store where it would store the PID of the process in some file on that dir and then prevent another Store from running if that file & PID exists.
