[SOLVED] df shows 53G disk usage, but du only 14G

[mk01]

@wuschl,

just to make this clear.

although there is /, /home and /lib/modules as separate mounts, all three are just sub-volumes of one btrfs filesystem - all three share one common space - size of partition.

that means if you rootfs (system) eat up 500MB and you home 50GB, they will all show 50,5 GB used.

btw: if you want to prevent mounts from being calculated in total, just add "-x" switch to "du". it means don't traverse outside filesystem.

Code:

du -shx /

will sum / without /home and without /lib/modules (and possibly other mounts in /media, /mnt …)
