Hallo,
ich habe eine SLES 12 SP5 Maschine die gestern extrem lange zum Booten gebr= uacht hat: Jan 18 23:53:21 geneious systemd[1]: Startup finished in 3.310s (kernel) + = 2min 31.383s (initrd) + 9min 11.363s (userspace) =3D 11min 46.057s. Normalerseise dauert dies weniger als eine Minute, auf dem host l=C3=A4uft = eine kleine Postgres Datenbank, sonst nix.
Nachdem der Bootvorgang abgeschlossen war konnte ich mich anmelden, und die= CPU hat fast 100% IO gemacht. Ich habe dann iotop installiert (was nat=C3=BCrlich auch Minuten gedauert h= at). Als die Installation fertig war war aber die IO-Last weg.
Ein paar Sachen sind mir aufgefallen: Teilweise sind die Eintr=C3=A4ge nicht chronologisch: Jan 18 23:45:31 linux-8i1i systemd-journald[137]: Received SIGTERM from PID= 1 (systemd).

Wie kann das sein ?
Ich dachte beim Booten werden Dienste gestartet. Wieso werden dann im Journal so viele runtergefahren ?
