Hi - I am trying to add a new hdd to each of my 3 servers, and want to use a spare ssd partition on the servers for the db+wall. My other OSDs are set up the same way, but I can't seem to keep CEPH from creating the OSDs on the drives before I can actually create the OSD I am trying to use the commands ceph orch device zap cube.robeckert.us /dev/sda --force cephadm ceph-volume lvm create --bluestore --data /dev/sda --block.db /dev/sdc1
Two things: You cannot use "cephadm ceph-volume lvm create" in a cephadm orchestrated cluster because it will not create the correct container systemd units. Use "cephadm ceph-volume lvm prepare" to create the OSD and "ceph cephadm osd activate $HOST" to let the orchestrator create the daemons (systemd units for containers). AFAIK it is not possible to use a partition for a block DB device. Create a physical volume on your SSD, a volume group and then a logical volume for each DB device. Use the LV in the command line like this: cephadm ceph-volume lvm preparee --bluestore --data /dev/sda --block.db vgname/lvname Regards -- Robert Sander Heinlein Consulting GmbH Schwedter Str. 8/9b, 10119 Berlin http://www.heinlein-support.de Tel: 030 / 405051-43 Fax: 030 / 405051-19 Zwangsangaben lt. §35a GmbHG: HRB 220009 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
