deleting files, but storage space not changing

[Powerphil]

Hi all,
I have been moving files into the trash can on the raspberry pi, and when i empty the trash, the storage space on the SD card doesn't change. I have emptied the trash as both a root user and pi user. I've also tried sudo apt-get clean, but nothing changes. At the moment, i'm trying to "release" approx 3gig, so a significant amount.

Can anyone advise what I've done wrong?

You can use the following commands to see where the space is being used:

Code: Select all

$ alias DU='du --block-size=1M --max-depth=2 --one-file-system'
$ alias s0rt='sort --numeric'
$ cd /some/directory/where/you/thing/the/junk/is
$ DU | s0rt | tail

good candidates are /tmp and /home/pi

If you prefer a GUI try baobab (I haven't used it on the Pi but it's in the repo so it should work)

It's possible the filesystem is in a bit of pain, especially if the Pi has been shut down abruptly.
You can force a file-system check with

Code: Select all

$ sudo touch /forcefsck
$ sudo reboot

(usual disclaimer/warning about commands with sudo in them ...)

Hi,
I've used teh GUI, but I still can't see where the space is being taken up. All the files have been deleted, the trash can empties, but the space not released.
Any other ideas??

Did you try the forcefsck thing?
Post the output of sudo du --block-size=1M --max-depth=2 --one-file-system / | sort -n | tail and sudo fdisk -l

Code: Select all

3131 /root/.local

3G in that directory...

Code: Select all

Disk /dev/mmcblk0: 7888 MB, 7888437248 bytes

... that's close to half your SD card.

[Powerphil]

The SD card is a 8Gb card

[Powerphil]

sorry, read your last post wrong. Can I delete that directory or not?

[sprinkmeier]

I'd check to see what was in it first
