Showing used space -but cant find where - anthonyonions - 30th Jun, 2013 06:29 PM
Ive moved some movies that have finished downloading but I'm still showing 2.9g used space when running df -h.
I've also run 'find // -xdev -type f -size +10000000c -exec ls -ladh {} \;' but nothing is coming up there.
Anyone have any other ideas on how I can see where this space has gone to?
Thanks

Thanks

if you run "mount" you will see line like this:
Code:
/dev/mmcblk0p2 on / type btrfs (rw,noatime,thread_pool=1,compress=lzo,ssd,space_cache,autodefrag)the one column in red is fstype.
ok so no tags inside those windows, BTRFS (fifth column)

Ok thanks for that. I'll have a look when I'm at home tonight and post back.

/dev/mmcblk0p2 on / type ext4 (rw,noatime,data=ordered)
So it's ext4. Any ideas what I need to do to find what's taking this space up?
Thanks

isn't any folder with content mounted with network over it?
then it would be "hidden" to your searches.
if all unmounted, do "du -xhd1 / | sort -rh ", you will get list of top level folders by occupied space. then take the one really big, and change the "/" to the folder, like "du -xhd1 /usr | sort -rh" ... and with recursive approach you will hopefully find the cause.

ok thanks will give that a go. I normally move the directories to a mounted NAS drive, so I would likely start with something there.
I'll report back my findings.
Thanks again.

Ok I've run the above with the NAS drive turned off, and got the following:
root@xbian /home/xbian # df -h
Filesystem Size Used Avail Use% Mounted on
rootfs 7.3G 2.9G 4.4G 40% /
/dev/mmcblk0p2 7.3G 2.9G 4.4G 40% /
tmpfs 38M 240K 38M 1% /run
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 10M 0 10M 0% /dev
tmpfs 75M 0 75M 0% /run/shm
/dev/mmcblk0p1 34M 11M 23M 33% /boot
root@xbian /home/xbian # du -xhd1 / | sort -rh
553M /usr
50M /lib
15M /home
7.0M /sbin
3.6M /etc
40K /root
36K /media
16K /mnt
4.0K /srv
4.0K /selinux
0 /proc
0 /dev
To me that looks ok.
Thought I found something then. There were 2 files, both 1.3g in size in /var/log/samba - but deleting them has done nothing to the used space!

run e2fsck on unmounted partition.
RE: Showing used space -but cant find where - anthonyonions - 3rd Jul, 2013 04:21 AM
ok I'm lost now. What would I run it against? Not sure what the unmounted partition would be in my case.
I think this space issue came from an rsync that didn't finish nicely. I think my ssh client (on iPad) timed out and didn't finish the script that was running - if this sheds any more light on what might be the issue.

if you are on alpha5, try initramfs fail by changing root= to a disk which does not exists. it will write error (root not accessible) and drop to shell.
then, run e2fsck /dev/mmcblk0p2
then change cmdline.txt back
or take the card out put into other linux booted system and fix there.
RE: Showing used space -but cant find where - anthonyonions - 3rd Jul, 2013 05:20 AM
Ok thanks for your help. I am on Alpha5, but this is all waaaay beyond my unix skills. I think I'll just reinstall the SD again and set it up from scratch.
Thanks again for trying.

ok, so :
edit /boot/cmdline.txt
find root=/dev/mmcblk0p2 and change it to root=/dev/nothing
reboot
you will get command prompt with error message (not important)
run "e2fsck /dev/mmcblk0p2"
then edit /boot/cmdline.txt again with those steps:
mount -t vfat /dev/mmcblk0p1 /tmp
vi /tmp/cmdline.txt
in the vi editor, you have to press "i" to start editing
change root= to root=/dev/mmcblk0p2
now:
press ESC, then ":" and "w". hit enter
then run
umount /tmp; sync
reboot -f

Great thanks, I will give these steps a go. Thanks for dumbing them down to my level :-)
