hi, I have got a celeron server with 80gig HD with cPanel. The HD info is as followings:

Filesystem Type Size Used Avail Use% Mounted on
/dev/hda3 ext3 71G 1.7G 65G 3% /
/dev/hda1 ext3 198M 14M 174M 8% /boot
none tmpfs 247M 0 247M 0% /dev/shm

I am just wondering, when I create a user account, does the space count towards hda3 OR hda1?

I see most of the partition is in hda3, so I hope to use those space.

thanks for any help in advance.

/dev/hda3. /dev/hda1 is your boot partition, needed only to boot up your server.
