Hi, I'm running out of idea why my wal+db nvmes are maxed out always so thinking of I might missed the cache tiering in front of my 4:2 ec-pool. IS it possible to add it later? There are 9 nodes with 6x 15.3TB SAS ssds, 3x nvme drives. Currently out of the 3 nvme 1 is used for index pool and meta pool, the other 2 is used for wal+db in front of 3-3 ssds. Thinking to remove the wal+db nvmes and add it as a write back cache pool.
The only thing which makes head ache is the description: https://docs.ceph.com/en/latest/rados/operations/cache-tiering/#a-word-of-caution feels like not really suggested to use it :/ Any experience with it? Thank you. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
