A judicious setting of mon_osd_down_out_subtree_limit can help mitigate the

Hi,
do you know why the OSDs are not starting?
When I had the problem that a start does not work, I tried the 'ceph-volume
lvm activate --all' on the host, which brought the OSDs back up.
But I can't tell you if it is safe to remove the OSD.
Cheers
