Hello,
Is it possible to set up a multi-site Loki? Here are some specific questions:
Can I set up Ceph in the backend and configure replication between two sites?
Can I install Loki in monolithic mode at the other site and transfer the backups I collect here?
If Ceph can replicate, can we access and work on the data at the DR location with a simple Loki setup?
Looking forward to your feedback. Thank you.
I’ve not tried to do this myself, so I am just offering some opinions and guesses. Hopefully someone more knowledgable cane chime in as well.
I think active-passive is definitely reasonable. You can have the backend replicated, and have a separate configuration for your secondary site that’s identical to your primary site except the backend, and spin up when needed.
I think you’d run into challenges with active-active, primarily because of clustering of the writers / ingesters. But if your link between primary and secondary is low enough latency maybe this is not a problem. Unfortunately I just haven’t tried this so I don’t really know what the operational threshold is.
