Nach Softwareaktualisierung kein Zugriff auf NFS Verbindungen möglich

vkanitz · February 24, 2022, 7:01pm

Hey fellows,

gestern habe ich eine sehr umfangreiche Softwareaktualisierung durchgeführt (fast 2.000 Pakete). Seitdem habe ich keinen Zugriff mehr auf meine NFS Verbindungen. Ich kann auch keine NFS Dienste starten. Ich habe erst mal ein Rollback durchgeführt. Habt Ihr eine Idee, woran es liegen kann?

Viele Grüße
Volker

Mögliche Anfangspunkte bezüglich Diagnose sind:

@vkanitz:

Systemzeit?

Normalerweise, NFS verlangt nicht, dass alle Systemuhren synchronisiert sind –
Aber, ich möchte nicht wissen, welche Nebeneffekte auftauchen wenn, die Systemzeiten nicht synchronisiert sind.
Ja, ja, normalerweise „nur” die Zeitstempeln bezüglich Dateien, aber …

@vkanitz:

NFS Server Export – ist irgend ein Verzeichnis auf ein anderer Server in die NFS Exports Liste eingetragen?

vkanitz · March 8, 2022, 10:56am

Nein, es ist kein Verzeichnis auf einen anderen Server eingetragen.

Zwei Anmerkungen noch.

Wenn ich ein Rollback auf den vorherigen Stand mache, läuft alles wieder.
Ich benutze im Netzwerk außerdem zwei Leap Installationen. Dort funktioniert auch alles problemlos.

boo#1197349, aber ein bisschen voreilig, oder? Ihr habt ja noch nicht einmal an der Oberfläche gekratzt, z.B. das Paket auf die üblichen Verdächtigen eingegrenzt. Da könnt ihr Euch schon ein wenig anstrengen statt Foren-Themen nach Bugzilla kopieren zu lassen.
