I have 2*1000GB hard drives + 60GB SSD. When I'm running df -H I'm getting "wrong" information about the server's hard drives. The output

# df -H
Filesystem             Size   Used  Avail Use% Mounted on
/dev/md1                78G    48G    26G  66% /
tmpfs                  4.2G      0   4.2G   0% /dev/shm
/dev/md0               520M    46M   448M  10% /boot

    What does fdisk -l report? – skohrs Dec 11 '13 at 20:54
  • What makes you think the output is "wrong"? What output are you expecting? How does what you see differ from what you expected? – voretaq7 Dec 11 '13 at 23:00

df is for filesystems, not disks. As skohrs says, you'll want to use something like fdisk to deal with disks directly.


It would appear that you don't have your 2*1TB HDDs mounted anywhere. The only disk being shown is a MDRaid device of ~80 GB, presumably on your 80 (not 60) GB SSD.

To get your larger disks to appear, simply (format, if necessary, and) mount them.
