Migrating DB volume using ceph-bluestore-tool was a wrong step.
What's the alternative? Redeploying an entire cluster of spinners doesn't seem
very feasible.
As far as I understand, "ceph-volume lvm migrate" is the (better)
supported way for db migrations.
In our case that tool didn't work. The db was on a partition, not a LV,
and that case seems not to be supported by ceph-volume.
Best,
Sönke
