Hello,
I'm experiencing the very same problem as Lao Meng !
Actually, I was led to this bug because of the same message telling me that my
root partition was almost full.
The debugfs directory didn't happen at first. But I can see it now repeatedly.
Can it be related to this bug ? Or another
I've got something similar to this going on. Here's the data:
uname -a yields:
Linux eRuiServer 2.6.31-19-generic-pae #56-Ubuntu SMP Thu Jan 28 02:29:51
UTC 2010 i686 GNU/Linux
status ureadahead yields:
ureadahead stop/waiting
df yields:
Filesystem 1K-blocks Used
I'll add:
On any system I have ubuntu 9.10 ( ubuntu, xubuntu, etc ) installed and on boot
/ reboot
the following is present ( df -H ): /var/lib/ureadahead/debugfs
System performance is greatly reduced ( 20% - 40% est ), so far, a
simple reboot will remove this entry and performance is

This is affecting me when trying to copy a really large file mounted
over CIFS, and it then dies as if I had ran out of space (but haven't):
$ time cp Ewrapped.sql /var/lib/mysql/
cp: writing `/var/lib/mysql/Ewrapped.sql': No space left on device
