I am using a 64 MB QSPI formatted in some UBI partitions.
df is an applet of busybox 1.27.2
Actually,
~ # df -h
Filesystem Size Used Available Use% Mounted on
/dev/ubi0_0 3.1T 1.9T 1.2T 63% /
/dev/ubi1_0 1.6T 21.8G 1.5T 1% /conf
But, obviously, the size cannot be that! Anyway, the use % seems to be correct, for the files contained in the partitions weight few MB.
How do you explain that?
