Hello all, a year ago we started with a 3-node-Cluster for Ceph with 21 HDD and 3 SSD, which we installed with Cephadm, configuring the disks with `ceph orch apply osd --all-available-devices` Over the time the usage grew quite significantly: now we have another 5 nodes with 8-12 HDD and 1-2 SSD each, the integration worked without any problems with `ceph orch add host`. Now we wonder if the HDD and SSD are used as recommended, so that access is fast, but without My questions: how can I check what the data_devices and db_devices are? Can we still apply a setup as for example the second one in this documentation? https://docs.ceph.com/en/latest/cephadm/osd/#the-simple-case Some technical details: Xeans with plenty RAM and Cores, Ceph 16.2.5 with mostly default configuration, Ubuntu 20.04, separated cluster and public network (both 10 Gb), Usage as RBD (Qemu), Cephfs, and Ceph object gateway. (The latter is surprisingly slow, but I want to sort out the problem with the underlying configuration first.) Thanks for any helpful responses, Erich _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
