Hello Jason, Interesting, I used ‘rados ls’ to view the SSDPOOL and can’t see any objects. Is this the correct way to view the journal objects? rbd feature enable SLOWPOOL/RBDImage journaling --journal-pool SSDPOOL The symptoms that we are experiencing is a huge decrease in write speed ( 1QD 128K writes from 160MB/s down to 14MB/s ). We see no improvement when moving the journal to SSDPOOL ( but we don’t think it is really moving ) Kind regards, Glen Baars

We are running 12.2.7 and all bluestore. We have also tried the ceph.conf option (rbd journal pool = SSDPOOL ) Has anyone else gotten this working? The journal header was on SLOWPOOL or the journal data objects? I would expect that the journal metadata header is located on SLOWPOOL but all data objects should be created on SSDPOOL as needed.
