Re: Safe to remove osd or not? Which statement is correct?

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
 Boris
