eXtremeRAID 2000

[Vitezslav T. Se'm]

Dobry den.

        Pouzivam tento hw RAID od Mylexu zaroven se dvema 18GB LVD SCSI
disky (Slackware 7.1, linux 2.2.19 + ide patche + reiserfs 3.5.32).
Nastavil jsem mirror, udelal partition, udelal filesystem, namountoval,
nakopiroval data, odmountoval, shodil system, vypnul komp, odebral jeden
disk z pole, zapnul komp., nabootoval a nenamountoval.. :-( Pri pokusu o
mountovani "mount -t ext2 -o noatime /dev/rd/c0d0p1 /disk2" dostanu
zpravu "mount: /dev/rd/c0d0p1 is not a valid block device". Predpokladal
jsem, ze mirror pojede po odebrani jednoho disku v degradovanem rezimu,
nejede vsak vubec.

tady jsou drobnosti ze systemu
