On Behalf Of Frank Ritchie Hi all, I have a few questions on using BlueStore. With FileStore it is not uncommon to see 1 nvme device being used as the journal device for up to 12 OSDs. Can an adequately sized nvme device also be used as the wal/db device for up to 12 OSDs? Are there any rules of thumb for sizing wal/db? Would love to hear some actual numbers from users. thx Frank |
