Hi!

For sharing SSD between WAL and DB what should be placed on SSD? WAL or DB?

Our OSDs are BlueStore and are on regular hard drives. Each OSD has a partition on an SSD for its DB. Wal is on the regular hard drives. Should I move the wal to share the SSD with the DB?

you should put wal on the faster device, wal and db could share the same ssd partition,
