It looks like that caused the NFS mount to be totally unresponsive. So the workers got stuck trying to access it during initialization (and thus stayed offline). Manual filesystem commands also get stuck. I could not even unmount the filesystem again. It is exactly the same on all 3 sap workers. I'll have a look on the other machines to see whether they are equally badly affected.

The other hosts (piworker and openqaworker1) were not affected. That's strange but also good.

The NFS mount being stuck was also the reason why zypper was stuck on rpm --root / --dbpath /usr/lib/sysimage/rpm -U --percent --noglob --force --nodeps -- /var/cache/zypp/packages/devel_openQA/x86_64/openQA-common-4.6.1688565452.efc15ea-lp155.5933.1.x86_64.rpm and thus the zypper lock was stuck as well and thus salt was not able to apply states. It would be nice if this chain of problems leading to other problems was at least shorter…

SD ticket was resolved, so network is back. Regarding the NFS mount: We tried to fade out the use of that for years for good reasons. I think we should try again, e.g. only provide the mount on some limited workers with a special worker class e.g. "deprecated-nfs".
