Hi, this is somewhat embarrassing, but one of my colleagues fat fingered an
ansible rule and managed to wipe out /etc/systemd/system on all of our ceph
hosts.
The cluster is running nautilus on ubuntu 18.04, deployed with
ceph-ansible, one of our near-future tasks is to upgrade to the latest ceph
and cephadm, so I'm not looking forward to redoing the entire cluster using
ceph-ansible.
Normally I'd put on the workboots and start re-installing a broken host
from scratch, but I hope there's a faster way.
Is there any way to generate the ceph-owned contents of /etc/systemd/system
?
Depending on how your colleague did the job, that is if systemctl
daemon-reload was
executed or not, most information might be in systemctl list-units or
systemctl show <unit>.
This might be too late, but do stash the output of systemctl list-units
for later.
Unless --no-reload is used as arg, systemctl enable <service> actually
does daemon-reload.
