ats-tls-restart failed on cp4027
Closed, ResolvedPublic

Description

I've upgraded trafficserver to 8.0.5-1wm10 on cp4027, and restarted successfully the backend with ats-backend-restart.

After that, I've tried restarting the tls instance too, but the command failed:

root@cp4027:~# ats-tls-restart
ulsfo/cache_text/nginx/cp4027.ulsfo.wmnet: pooled changed yes => no
trafficserver-tls.service is not active, cannot reload.

Relevant logs at that time:

The restart looked ok, so I've pooled the service manually with:

confctl --host --quiet select name=cp4027.ulsfo.wmnet,service=nginx set/pooled=yes

I fixed the touch issue with https://gerrit.wikimedia.org/r/#/c/operations/puppet/+/550475/, but still update-ocsp-all tries to reload trafficserver-tls.service, which fails due to the unit being inactive. @Vgutierrez: ideas for how to tackle this?
