fix openqaworker-arm-1+2+3 recovery pipeline (was: likely stuck in reboot loop) size:M

Description
Observation¶
Both openqaworker-arm-1+2 seem to be stuck in reboot&recover loops according to alerts and observations from https://monitor.qa.suse.de/d/1bNU0StZz/automatic-actions. I paused according alerts to also not trigger https://gitlab.suse.de/openqa/grafana-webhook-actions. Maybe the problem is actually within the gitlab CI runners which seems to have problems to resolved hosts like openqaworker-arm-1, see https://gitlab.suse.de/openqa/grafana-webhook-actions/-/jobs/1069000#L8253:
ping: openqaworker-arm-1: No address associated with hostname
ping: openqaworker-arm-1: No address associated with hostname
ping: openqaworker-arm-1: No address associated with hostname
…
After pausing the alerts and cancelling the still running gitlab CI recovery job for openqaworker-arm-1 I could follow in ipmi-openqaworker-arm-1-ipmi sol activate that the machine was coming up just fine (with the usual horribly long boot times).
Acceptance criteria¶
- AC1: All o3 arm workers can be recovered by the automatic pipeline
- AC2: No arm workers are recovered and continue to run when they are fine
- AC3: We know what the expected domain setup is
Suggestions¶
- Check and compare DNS resolution in according environments within gitlab CI runners as well as locally.
- Maybe as a workaround it helps to use the FQDN in the gitlab CI environment
- Fix the issue with the help of SUSE-IT as they recently changed the gitlab CI runners, maybe that had some impact
Rollback steps¶
- Subject changed from fix openqaworker-arm-1+2 recovery pipeline (was: likely stuck in reboot loop) to fix openqaworker-arm-1+2+3 recovery pipeline (was: likely stuck in reboot loop)
- Priority changed from High to Immediate
openqaworker-arm-3 is also affected now, see failed gitlab CI pipeline for recovery, paused alert
- Description updated (diff)
I just tested that inside different Gitlab CI:
$ cat /etc/resolv.conf
### /etc/resolv.conf is a symlink to /var/run/netconfig/resolv.conf
### autogenerated by netconfig!
#
# Before you change this file manually, consider to define the
# static DNS configuration using the following variables in the
# /etc/sysconfig/network/config file:
# NETCONFIG_DNS_STATIC_SEARCHLIST
# NETCONFIG_DNS_STATIC_SERVERS
# NETCONFIG_DNS_FORWARDER
# or disable DNS configuration updates via netconfig by setting:
# NETCONFIG_DNS_POLICY=''
#
# See also the netconfig(8) manual page and other documentation.
#
### Call "netconfig update -f" to force adjusting of /etc/resolv.conf.

Retrigger won't work as it will reuse the old configuration. We need a new run based on the new commit.
yes, done
Much better (at least the DNS part)

agreed.
Can you report a ticket with SUSE-IT, maybe the change was unintented on their side.

ok, good to know. Then I suggest could you please quickly check other common gitlab CI pipeline configs if we might run into the same problem there?
