I would agree with that. So, here is what I am planning on doing today. I will try this from scratch on a different OSD node from the very first step and log input and output for every step. Here is the outline of what I think (based on all the email exchanges so far) should happen.
******* Trying to convert osd.120 to Bluestore. Data is on /sda/sdh. Filestore Journal is on a partition drive (40GB) on /dev/sda. #Mark those OSDs out ceph osd out 120 # Stop the OSDs systemctl kill ceph-osd@120 # Unmount the filesystem sudo umount /var/lib/ceph/osd/ceph-120 # Destroy the data ceph-volume lvm zap /dev/sdh --destroy # data disk ceph-volume lvm zap /dev/sda --destroy # ssd for wal and db # Inform the cluster ceph osd destroy 70 --yes-i-really-mean-it # Check all the /etc/fstab and /etc/systemd/system to make sure that all the references to the filesystem is gone. Run ln -sf /dev/null /etc/systemd/system/ceph-disk@70.service # Create PVs, VGs, LVs pvcreate /dev/sda # for wal and db pvcreate /dev/sdh # for data vgcreate ssd0 /dev/sda vgcreate hdd120 /dev/sdh lvcreate -L 40G -n db120 ssd0 lvcreate -l 100%VG data120 hdd120 # Run ceph-volume ceph-volume lvm prepare --bluestore --data hdd120/data120 --block.db ssd0/db120 --osd-id 120 # Activate ceph-volume lvm activate 120 <osd fsid> ****** Does this sound right?
