What is your database size


When I migrate my infra to Hetzner There are a few disk limit such ad max 10TB per volume. On bare metal, max I can get for nvme is 24tb.

I though i never hot these

I found myself now learning table space, btrfs to join multiple volume or sepearate index/table into different volume. my database now even for a 2 years app get to 40tb.

I looked around and even on aws boggest ebs volume is 64tb.

what storage you are using? and what size is it?

At ~35TB Postgres we ended up separating pg_wal onto its own volume first — write amplification there was quietly eating 20–30% of our NVMe throughput before we caught it.
