Description Asaf Rachmani 2022-03-09 13:58:51 UTC 
Description of problem:
Under "Crash dump location" when the location is "Remote over ssh"
the default value for the directory field is "/var/crash" and cannot be empty, if the path does not exist on the NFS, the operation will fail with the following error:
"Unable to apply settings: Error: systemd job RestartUnit ["kdump.service","replace"] failed with result failed"

Version-Release number of selected component (if applicable):
cockpit-260-1.el8.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Launch cockpit "http://localhost:9090"
2. Set crash dump location to "Remote over NFS"
3. Use the default value in the Directory field and make sure it doesn't exist on the NFS
4. Test kernel dump

Actual results:
Getting an unclear error message - "Unable to apply settings: Error: systemd job RestartUnit ["kdump.service","replace"] failed with result failed"

Expected results:
Get a clear error message

I improved this in https://github.com/cockpit-project/cockpit/pull/17214 , the dialog now shows the kdump.service journal to give more details. kdump's error message is still confusing though, I filed bug 2071529 about that. When that is fixed, it should be clear enough. Thanks!
