Hej

Jeg har en gammel server med FreeBSD 4.6.2-RELEASE-p2. Der sidder tre diske i, og ifølge ham som installerede den, skulle den være sat op så de to 18GB diske er spejlede, og indeholder alle vigtige data, men ifølge nedenstående df og fdisk på de tre diske i serveren, ser det ud som om de 2 18GB diske slet ikke bliver brugt. Jeg er dog ikke så skråsikker at jeg tør slette de partitioner som ligger på dem, og sætte dem op så de kan bruges til data, uden først at sende nedenstående output her, og håbe på feedback fra en som er mere kyndig end mig.

Ser det ud til at jeg kan slette de 2 18GB diske? Eller risikerer jeg at miste data. Serveren hoster et par forskellige websites, så jeg kan hurtigt få ballade hvis jeg kommer til at ødelægge noget.

På forhånd tak for hjælpen,

Niels
