This question already has an answer here:

This error recently appeared on my Raspberry Pi. I get this error when I try to autocomplete folder paths. It won't autocomplete commands at all. I don't get this error when I'm logged in as root.

When I do df -i I get:

Filesystem     Inodes  IUsed  IFree IUse% Mounted on
/dev/root      399840 157845 241995   40% /

tmpfs          118466      4 118462    1% /run/user/1000

When I do df -h I get:

Filesystem      Size  Used Avail Use% Mounted on
/dev/root       5.9G  5.7G     0 100% /
devtmpfs        459M     0  459M   0% /dev
tmpfs           463M     0  463M   0% /dev/shm

tmpfs            93M     0   93M   0% /run/user/1000

So it seems like my root is out of storage. I already removed files and uninstalled packages but nothing seems to change the outcome of df -h.

Please help, what am I doing wrong? Thanks in advance.

EDIT:

du -smh / gives me:

du: cannot access ‘/proc/2667/task/2667/fd/3’: No such file or directory
du: cannot access ‘/proc/2667/task/2667/fdinfo/3’: No such file or directory

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Can you edit to append the output of du -smh /? Also, which filesystem are you using and have you made any changes to permissions lately? – Schives May 18 '17 at 23:55
  • du: cannot access ‘/proc/2667/task/2667/fd/3’: No such file or directory du: cannot access ‘/proc/2667/task/2667/fdinfo/3’: No such file or directory du: cannot access ‘/proc/2667/fd/4’: No such file or directory du: cannot access ‘/proc/2667/fdinfo/4’: No such file or directory 5.7G / I'm using ext2/ext3 And yes, I've recently added a new user which I gave sudo permissions, I also gave that user access to some folders – Camel May 18 '17 at 23:58

It's nand based storage, you've deleted data recently, and shown no difference in usage. It seems to me that you might need to trim (or the equivalent for mmc - but I have almost no experience with mmc devices, so I could be wrong): have you tried sudo fstrim /?

  • I did this as well, after the problem was already fixed, but it didn't change the outcome of df -h – Camel May 19 '17 at 8:32

I don't know why I didn't think of this before but the solution in my case turned out to be sudo apt-get clean aftwer which df -h gave the following output:

Filesystem      Size  Used Avail Use% Mounted on
/dev/root       5.9G  5.2G  373M  94% /
devtmpfs        459M     0  459M   0% /dev
tmpfs           463M     0  463M   0% /dev/shm
tmpfs           463M  7.8M  455M   2% /run
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           463M     0  463M   0% /sys/fs/cgroup
/dev/mmcblk0p6   65M   21M   45M  32% /boot
tmpfs            93M     0   93M   0% /run/user/1000

Thanks for your time and input, Schives.
