Description

Observation

It seems that openqaworker5 is down since early morning: https://stats.openqa-monitor.qa.suse.de/d/WDopenqaworker5/worker-dashboard-openqaworker5?tab=alert&viewPanel=65105&orgId=1&from=1651359305036&to=1651398742983
The host is reachable via IPMI and it is up.

Suggestions

  • ipmi-openqaworker5-ipmi sol activate allowed login but the network was down. There is one failed service "os-autoinst-openvswitch" failed with can't parse bridge… which could be the cause or is just a symptom of another network issue. okurz triggered systemctl start default.target. Check again if it's reachable, login over SoL, check logs, try multiple reboots, fix any problems in network config or os-autoinst-openvswitch
  • We already have multiple levels of retry, e.g. in os-autoinst-openvswitch. Check if this retry was not enough, different problem, or add more retrying on systemd level

Judging by the code, the exception in the end is "normal" if the bridge's IP isn't assigned in time.

The timeout has already been increased:

# /etc/systemd/system/os-autoinst-openvswitch.service.d/30-init-timeout.conf
[Service]
Environment="OS_AUTOINST_OPENVSWITCH_INIT_TIMEOUT=1200"

(There are no further drop-in configs for the service.)

The full journal shows that the network took apparently very long to setup as other services run into network-related errors as well:

The network was not restored automatically so a retry within/of our service wouldn't have helped (as it didn't help for the cache service).

The network has only been restored on the next day:

I suppose that happened only because okurz invoked systemctl start default.target.


So the failing os-autoinst-openvswitch is a mere symptom and further retried wouldn't help. It looks like wicket's startup got stuck due to a dependency issue:

#7 Updated by cdywan about 2 months ago

  • This looks to be a dependency issue / race condition
  • Can we reduce the prio to High?
    • Yes, it is not happening everywhere; not sure how to even reproduce it
  • It seems related to the overarching multi-machine setup / how we manage the network
    • Not really; none of that units were part of the dependency cycle.

#9 Updated by mkittler about 2 months ago

We're not the only ones with this kind of issue (e.g. https://bugs.launchpad.net/ubuntu/+source/nbd/+bug/1487679, https://forum.siduction.org/index.php?topic=7993.0, https://bugzilla.redhat.com/show_bug.cgi?id=1600823). There's even a SUSE-specific issue (https://www.suse.com/zh-cn/support/kb/doc/?id=000018796) but we are not in that particular situation. (We have a nfs mount but there are no nested mounts within.)

I'm still trying to figure out which of the services in "our" cycle is the culprit.

#10 Updated by mkittler about 2 months ago

TLDR: I suspect the culprit is Before=xvnc.socket in YaST2-Firstboot.service/YaST2-Second-Stage.service. Note that this is also the only significant difference to my TW system where I reboot very often and never run into this issue.


This is the list of dependencies systemd's walked through until it detected the cycle (same order as in the journal entry):

 1. network-online.target                systemd's starting point
 2. wicked.service/start                 because `Before=network-online.target`, makes sense
 3. wickedd.service/start                because `Before=wicked.service`, makes sense
 4. wickedd-auto4.service/start          because `Before=wickedd.service wicked.service`, makes sense
 5. dbus.service/verify-active           because `systemctl list-dependencies --before dbus.service` shows `wickedd.service` (and other wicked services)
                                         but why? maybe because it requires a socket unit (`Requires=dbus.socket`) which in turn requires any of the previous points
                                         it is the same on my TW system (except that the precessor is `NetworkManager.service`)
 6. basic.target/start                   because `systemctl list-dependencies --before basic.target` shows `wickedd.service` (and other wicked services)
                                         but why? it is *not* due to the NFS mount because it is the same on my TW system (except that the precessor is `NetworkManager.service`)
 7. sockets.target/start                 because `systemctl list-dependencies --before sockets.target` shows `basic.target`
                                         but why?
 8. xvnc.socket/start                    because `systemctl list-dependencies --before xvnc.socket` shows `sockets.target`
                                         presumably due to `WantedBy=sockets.target`
 9. YaST2-Firstboot.service/start        because `Before=xvnc.socket` (8.), does it make sense?
10. YaST2-Second-Stage.service/start     because `Before=xvnc.socket` (8.), does it make sense?
11. systemd-user-sessions.service/start  because `systemctl list-dependencies --before systemd-user-sessions.service` shows `YaST2-Second-Stage.service`
                                         due to `After=systemd-user-sessions.service` in YaST2-Second-Stage.service
12. remote-fs.target/start               because `systemctl list-dependencies --before remote-fs.target` shows `systemd-user-sessions.service`
                                         due to `After=remote-fs.target` in systemd-user-sessions.service
13. iscsi.service/start                  because `Before=remote-fs.target`
14. network-online.target/start          because `After=network-online.target` in iscsi.service
  • I assume the list is sorted so a unit further down the list needs to be started before a unit further up in the list.
  • I guess then the most interesting question is why remote-fs.target is required by any of the units further up in the list because it is of course wrong requiring this target to be started before network-online.target (while it makes sense that remote-fs.target itself requires to be started after network-online.target).
  • I've been comparing this to my TW system (which I reboot daily and sometimes more often but never experienced that problem). It looks very similar except that wicked services are replaced by NetworkManager.service. There's are other differences, though:
    • The YaST2 services (9. and 10.) do not have the ordering Before=xvnc.socket.
    • Actually there are no further differences. I assume it is really the YaST2 services which make the difference.

the NFS mount is only required by the worker and the ordering doesn't look cyclic. So I don't think the NFS mount is the culprit.

#11 Updated by mkittler about 2 months ago

If the conclusion from my last comment is right, the problematic package is yast2-installation developed at https://github.com/yast/yast-installation. I found the PR https://github.com/yast/yast-installation/pull/1041 in that repository and it looks like our issue, indeed. (Except that another unit in the cycle is deleted in their case but I assume the concrete unit which is deleted to break the cycle is a random pick.) Note that I haven't found this issue when Googling for the error message because it only contains the error message in form of a screenshot. (If I would have found the issue that would have saved me a lot of my own investigation.)

So we need to get yast2-installation updated on our system or fix is via a drop-in config.

To receive the proper fix would likely mean waiting for https://build.suse.de/request/show/270972 to be accepted into SLE and then forwarded to Leap. As a workaround you could try the drop-in or actually rollback yast2-installation to an earlier, unaffected version and lock the package until we have the SLE update available.

  • Status changed from In Progress to Feedback
  • Priority changed from Urgent to Normal

Considering the change has already been picked on the SLE-15-SP3 branch (see https://github.com/yast/yast-installation/blob/SLE-15-SP3/package/YaST2-Firstboot.service) I suppose all we have to do is waiting to receive the change.

Note that using a drop-in config to fix the dependency only on systemd level is likely not the best idea because the proper revert also contains other changes. So I've been downgrading our hosts with sudo salt '*' cmd.run 'zypper --non-interactive --no-refresh in --oldpackage http://download.opensuse.org/distribution/leap/15.3/repo/oss/noarch/yast2-installation-4.3.37-1.1.noarch.rpm && zypper addlock yast2-installation'. Since the issue has been worked around I'm lowering the priority.

So I'm waiting for a new version (should likely show up on http://download.opensuse.org/update/leap/15.3/oss/noarch) and if it looks good I'll remove the lock again.

I've just tried upgrading but still got the broken yast2-installation-4.3.50-150300.3.27.1.noarch.

Apparently we're waiting for https://smelt.suse.de/request/272018.

Still no progress. Setting to "Blocked" because the issue is blocked by https://smelt.suse.de/request/272018.

Ondřej offered to help with that. Either way I'll bump the due date since this is pending the review.

#18 Updated by mkittler about 1 month ago

  • Status changed from Blocked to Resolved

The request has been accepted and 4.3.52-150300.3.30.1 is available. It looks good on openqaworker5 so I've been removing the locks on all other hosts as well and consider this done.
