Description
Observation¶
openqaworker13 was unreachable on 2021-02-22.
Acceptance criteria¶
- AC1: machine is reboot-reliable, e.g. ensured by multiple reboots without failures after boot
Problem¶
Cannot connect to this machine ping.
using ipmitool sol activate connect to this machine, shows:

Then did ipmitool power cycle. The workers on that host works well for now.
Suggestions¶
- Remove from salt
- Identify problem
- Ensure stability with multiple reboots
- Add back to salt after stable
Workaround¶

From the logs it is hard to tell what's wrong. I suppose one really had to reboot the machine a few times to find out what's wrong (and remove it from salt before). (I'm not doing that now and hence unassign myself again.)
Updated by mkittler over 3 years ago
I've power-cycled and regularly restarted the machine. The only problem I've found so far is that the NFS mount doesn't work. It correctly depends on network-online.target:
systemctl list-dependencies var-lib-openqa-share.mount
var-lib-openqa-share.mount
● ├─-.mount
● ├─system.slice
● ├─var-lib-openqa.mount
● └─network-online.target
● └─wicked.service
However, reaching that target does not mean the eth network connection is already up:

Updated by mkittler over 3 years ago
I did power cycle, power reset and some more regular reboots. The mentioned NFS problem was always reproducible but the system booted without problems. So what ever causes the initial problems, it is not apparent anymore. So we can likely close the ticket.
Not sure about the NFS problem. My reboots and the NFS problem together causes the monitoring alerts (so the alerts can be ignored).
By the way, since the worker was offline for a while it hadn't had my recent manual setup changes applied. I took the opportunity to do that now. It should now be on-par with the other workers.

I suggest we still handle the NFS issue. If you prefer make that a separate ticket though
