[kwlug-disc] Degraded systems (all of mine, yours too (probably))

[Ron]

For reasons unknown, I ran the following on a machine today:

 > # systemctl is-system-running
 > degraded

Uh-oh.  *All* my machines were like this. Some due to, i.e., `certbot` 
failing to renew a cert for an expired domain.


To find out what's going on, I ran:

# systemctl list-units --state failed
   UNIT                     LOAD   ACTIVE SUB    DESCRIPTION 
           ● cantonese-milter.service loaded failed failed Rewrite 
Cantonese Word-of-the-Day

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

1 loaded units listed.


I was then able to fix the failed unit(s) and now:

# systemctl is-system-running
running



Curious, am I really sloppy, or is it common to have a failed unit on 
machines? What are your results?
