bash: echo: write error: No space left on device

I am using Ubuntu Linux and using this as PHP server hosting the scripts and sites in /var/www/. I am getting bash: echo: write error: No space left on device but there is huge space left on the device. I have found on google about this issue but no one suits my problem as people were getting this error after running some commands but I am getting it just after running gksudo nautilus yesterday,

I am unable to umount any drive please suggest me what to do

I have run $ sudo apt-get clean

I have run $ sudo apt-get autoremove

I am getting this message after running `$ df -k

Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda7 93956704 89329640 0 100% / udev 1989324 4 1989320 1% /dev tmpfs 799256 1076 798180 1% /run none 5120 0 5120 0% /run/lock none 1998132 3324 1994808 1% /run/shm overflow 1024 16 1008 2% /tmp /dev/sda2 240367612 192464952 47902660 81% /media/CE48787148785A63 bash: echo: write error: No space left on device 

when running $ df -h

after running disk free command with -k and -h flags. It is clear that My device has ample space to work on. If someone has resolved the same issue please help me.

I believe you are hitting the limit on your /dev/sda7 drive that isn't reserved. To see more about reserved space, please see:

To lower the amount of space reserved (looks like it is currently set at 2%), you can run the following command to lower it:

sudo tune2fs -m 1 /dev/sda7

Please note that the reserved space is there for a reason. This will cause issues later if you continue to use up more space.
