I have a squid package-installed test cluster that I am trying to adopt into cephadm. Monitors & managers have been adopted, and the orchestrator is functioning. When I try to adopt an OSD though (e.g. osd.0), cephadm creates the new directory (<fsid>/osd.0) and populates the files from the legacy directory. It then crashes complaining that the directory osd/ceph-0 is not empty so cannot be removed. In some cases none of the files have been removed, and in others the block symlink and require_osd_release file remain. I can remove the new <fsid>/osd.0 and use ceph-volume to activate the OSD again. cephadm.log reports that every file has been moved and the ownership set - even for files that still remain in the legacy directory. It doesn't report any other errors (apart from the directory not empty error. when it crashes). I really can't find where to go from here. Any pointers appreciated... Thanks, Chris
