Hello, because of a performance problem I've checked services and noticed this line: ● shadow.service loaded failed failed Verify integrity of password and group files So I checked this service and got this output: $ systemctl status shadow ● shadow.service - Verify integrity of password and group files Loaded: loaded (/usr/lib/systemd/system/shadow.service; static; vendor preset: disabled) Active: failed (Result: exit-code) since Wed 2018-12-12 06:59:27 CET; 14h ago Process: 561 ExecStart=/bin/sh -c /usr/bin/pwck -r || r=1; /usr/bin/grpck -r && exit $r (code=exited, status=1/FAILURE) Main PID: 561 (code=exited, status=1/FAILURE) Dez 12 06:59:24 tuchola systemd[1]: Started Verify integrity of password and group files. Dez 12 06:59:26 tuchola sh[561]: Benutzer »ceph«: Verzeichnis »/run/ceph« existiert nicht. Dez 12 06:59:26 tuchola sh[561]: pwck: Keine Änderungen Dez 12 06:59:27 tuchola systemd[1]: shadow.service: Main process exited, code=exited, status=1/FAILURE Dez 12 06:59:27 tuchola systemd[1]: shadow.service: Failed with result 'exit-code'. As system seems to run without problems (other than performance), I've got two questions: 1. Do I need the shadow service? Why? 2. Why does it fail? User "ceph" is defined, but /run/ceph does not exist as its home directory - why? Seems there's a problem in the installation of ceph-libs or any or its dependants (like libvirt). Probably the user is created only if whole ceph is installed, too? Kind regards Peter
