Description

Hello

In almost all systemd unit files (like ceph-mgr, ceph-osd...) there is an override for CLUSTER environment entry.
Example (https://github.com/ceph/ceph/blob/mimic/systemd/ceph-mgr@.service.in)

EnvironmentFile=-@SYSTEMD_ENV_FILE@
Environment=CLUSTER=ceph

So CLUSTER variable is always set to ceph and we are unable to use custom value in any configuration file.
The solution is to swap those two lines

History

#1 Updated by Jacek S. almost 5 years ago

After an investigation of Systemd documentation I found an information: https://www.freedesktop.org/software/systemd/man/systemd.exec.html

Settings from these files override settings made with Environment=

so looks like a bug in systemd (229, Ubuntu Xenial)
