[SQL] Different size in the DATA directory

[Maurício Sessue Otta]

Hi, in my production server a "du -hs" in the DATA directory returns 21GB in a newly installed server, after I restored the dumps from the production server, the "du -hs" gives me just 8GB   why is there such a diference???   what should I do (besides buying bigger and bigger HDs) ???   []'s Mauricio
