Linux: df: cannot read table of mounted file systems


Warning: Use of undefined constant user_level - assumed 'user_level' (this will throw an Error in a future version of PHP) in /homepages/3/d98111892/htdocs/insanelabs/htdocs/wp-content/plugins/ultimate-google-analytics/ultimate_ga.php on line 524

“df -l” returned an error: “df: cannot read table of mounted file systems”. I looked at my “/etc/mtab” file – empty! I did a “fdisk -l” and saw my partitions there, then proceeded to create a new mtab from my /proc/mount:
grep -v rootfs /proc/mounts > /etc/mtab

Error message: no space left on the device!

Ran out of room… my SQL dumps are taking a lot of space 🙁 Freed up some space and executed the command again – df is now returning what it’s supposed to return.

      Do a df -l and check your partitions, one should say 100% used – clean it up.
