tune2fs er et program som bruges til at \u00e6ndre p\u00e5 m\u00e5den OS bruger disken p\u00e5.<\/p>\n

En af de ting du kan \u00e6ndre er reserveret plads.<\/p>\n

Selve kernel reservere normal 5% af disken til kernel ting. Det kan \u00e6ndres hvis du har en stor disk.<\/p>\n

Her s\u00e6tte vi den til 1% af disk pladsen.<\/p>\n
