Hallo zusammen,

ich habe einen Root-Server als Medien-Server mit Ubuntu 18.04.5 LTS (4.15.0-144-generic).. Seit 2 Tagen läuft dieser nicht mehr richtig und ich hab hohe CPU Last.

Wenn ich mich per SSH einlogge kommt die Meldung:

System information disabled due to load higher than 2.0

Ich wollte daher mal wieder update, bekomme aber die folgende Fehlermelung:

root@v22018:~# apt-get update

Hat jemand eine Ahnung was da mit meiner Maschine los ist?

Vielen Dank und viele Grüße

Sieht glatt so aus, alsob da keinen vollständigen Netzwerkzugriff besteht (da sein muss er ja, sonst würde kein SSH funktionieren) oder ein DNS-Problem. Lässt sich so komplett ohne verwertbare Informationen aber schlecht sagen.

Hey tomtomtom,

Kannst du darauf etwas erkennen? Ich hab das Gefühl die DNS können nicht aufgelöst werden.

Vielen Dank und viele Grüße

Das ist komisch.

Hey DJKUhpisse,

gerne:

root@v22018117216076728:/# systemd-resolve --status --no-pager
Failed to get global data: Unit dbus-org.freedesktop.resolve1.service not found.

Gut, dann ist das nicht "Standard". Hast du den Dienst (absichtlich) abgestellt? Wenn nein aktivieren.

sudo systemctl enable systemd-resolved

Dann starten.

Hey DJKUhpisse,

vielen lieben Dank, das war es. Bewusst hab ich den dienst nicht abgestellt, keine Ahnung wieso das der Fall war.

Hauptsache es funktioniert wieder alles

Danke nochmal und noch einen schönen Sonntag
