opsi-linux-bootimage - Error checking /dev/sda4. partition
Verfasst: 02 Aug 2025, 12:32
Moin,
ich bin aktuell dabei, das win11-x64 Paket auf mehreren Rechnern (UEFI) per PXE-Boot über das opsi-linux-bootimage zu installieren. In seltenen Fehlern schlägt das Erzeugen der WinPE-Partition in /dev/sda4 fehl. In meinem Fall habe ich 8 völlig identische Acer Travelmate Spin B3 Geräte, wo zwei den Fehler hatten. Aber auch auf anderen Computern, wenn auch deutlich seltener, habe ich das Fehlerbild gesehen.
Auf einem der 8 Geräte habe ich die Installation mehrfach neugestartet und es hat nicht funktioniert. Auch ein vorheriges löschen der Partitionstabelle mit dd if=/dev/zero of=/dev/sda hat nicht geholfen. Was am Ende funktioniert hat, war sich per SSH mit dem Bootimage zu verbinden und manuell den Befehl "master" auszuführen (obwohl /dev/sda4 schon existierte). Dann lief die Installation einwandfrei durch.
Das Fehlerbild wirkt wie eine merkwürdige Race-Condition, die nur in bestimmten Fällen aufzutreten scheint.
Soweit ich das sehe ist der Source-Code des linux-bootimages nicht öffentlich, oder? Ansonsten könnte ich hier ggf. noch tiefer reinschauen, was hier passiert.
