I'm running CentOS and have a 100GB Micron RealSSD P300. It appears that the drive is almost full, as noted by running df
:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda3 94753636 86002428 3937948 96% /
tmpfs 12298364 0 12298364 0% /dev/shm
/dev/sda1 253871 58571 182193 25% /boot
However, running du /
tells another story:
6.9M /bin
56M /boot
188K /dev
28M /etc
3.3M /home
251M /lib
25M /lib64
16K /lost+found
4.0K /media
4.0K /mnt
8.0K /opt
0 /proc
11M /root
18M /sbin
4.0K /selinux
0 /service
4.0K /srv
0 /sys
436K /tmp
1.4G /usr
1.9G /var
What could be taking up all of these blocks that I can't see? Could the drive just be broken? I don't have too much experience working with SSDs, so perhaps there's an obvious step I'm missing?
du
as root, right? Else it may be time for afsck
