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?
