Hi. I'm currently trying out cephadm, and I got into a state that was a bit unexpected for me.
I created three host machines in VirtualBox to try out cephadm. All drives I made for OSD are 20GB in size for simplicity. Bootstrapped one host with one drive and then added the other two. Then they directly added all available drives, so now I had 3x20 GB OSDs. Watching the GUI, it said I could add WAL and DB devices, I never figured out how to do that in the GUI, but I tried to do it manually. ceph osd destroy osd.2 --force ceph-volume lvm zap --destroy /dev/sdb ceph auth get client.bootstrap-osd > /var/lib/ceph/bootstrap-osd/ceph.keyring ceph-volume lvm prepare --data /dev/sdb --block.db /dev/sdc --block.wal /dev/sdd ceph-volume lvm activate 2 d4a590eb-c0f6-47bc-a5fa-221bf8541e09 It worked, and I got the new OSD registered, but the strange thing was that it was 40 GB and half full. Is this expected? Best regards Daniel _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
