Probleme mit newfs und großer Disk
Sonnenbrand:
Frage an die Experten,
ich habe hier eine große logische Partition (ca. 840GB - HW-RAID5 aus 4x300GB in einem SE3310) auf der ich mittels newfs ein UFS-FS anlegen will. Dabei "nervt" mich newfs mit diversen Fehlermeldungen und Warnings:

letztendlich bekomme ich ein FS - bin mir aber angesichts der Warnings nicht sicher ob meine newfs-Optionen nun der letzte Hit sind. Was meint Ihr?

Aber die Warnings gefallen mir irgendwie nicht.

7ami7:
Sieht wie ein newfs und nicht wie ein mkfs aus.

Das klingt jetzt wie die Standardantwort vom Sun-Support, aber dein Kernel scheint schon etwas älter zu sein: mal ein wenig auf Sunsolve stöbern und ggf. einen aktuelleren Patch-Stand einspielen. Ich habe dunkel in Erinnerung, dass es mit Dateisystemen im Bereich 1TB Probleme gab.
