Hello,
It may not be a bug at all, but I was surprised to find out that 'du
-x' is reporting a lower disk usage on /mnt when partitions are
mounted.
Here is an example with '/mnt' belonging to the same filesystem as '/'
:
linux$ LANG=EN ls -l /mnt
total 12
drwxr-xr-x 2 root root 4096 Jul 8 2018 VL1800
drwxr-xr-x 2 root root 4096 Jul 8 2018 data
drwxr-xr-x 3 root root 4096 Aug 19 13:24 nfs
# I mount two partitions from other disks on /mnt
linux$ sudo mount /mnt/VL1800
linux$ sudo mount /mnt/data
linux$ du -x /mnt
4 /mnt/nfs/nas
8 /mnt/nfs
12 /mnt
# I unmount the two partitions
linux$ sudo umount /mnt/VL1800
linux$ sudo umount /mnt/data
linux$ du -x /mnt
4 /mnt/data
4 /mnt/VL1800
4 /mnt/nfs/nas
8 /mnt/nfs
20 /mnt
/mnt is now bigger.
Is this a normal result, because even when mounted, physically, the
directories '/mnt/VL1800' and '/mnt/data' still exist on the '/'
filesystem, or not ?
Shouldn't they still occupy 4Kb of disk space each on the '/'
filesystem when partitions are mounted ?
Best regards,
Joseph Paul
