Hi all,
The first step is to mark an OSD down, in Hammer one can achieve this in this way:
ceph osd out osd.3
/etc/init.d/ceph stop osd.3
However, in Jewel, package like ceph-10.2.2-0.el7.x86_64 no longer offers /etc/init.d/ceph, thus making it "unable to stop an OSD".
I noticed the package of ceph-10.2.2-0.el7.x86_64.rpm
is only 3176 bytes on official site: http://download.ceph.com/rpm-jewel/el7/x86_64/
Compared to Hammer ceph-0.94-0.el7.centos.x86_64.rpm 17156672 bytes.
I also noticed in the official JEWEL release notes, systemd is used instead. I also tried systemctl ceph stop osd.3 or systemctl stop osd.3:
# systemctl ceph stop osd.3
Unknown operation 'ceph'.
# systemctl stop osd.3
Failed to stop osd.3.service: Unit osd.3.service not loaded.
So my question is how to remove OSD in JEWEL? To be more specific, how to mark an OSD down?
Thanks.
