Hi,

I have a problem with xfs filesystem. I have lost a file. So:

root@rigodon log # pwd
/var/log
root@rigodon log # ls -al lastlog
- -r-------- 1 root root 146292 ago 11 10:44 lastlog root@rigodon log # du -sh * | grep lastlog
7,6G lastlog

I have a file witch size is 7,6 GB. However, if I ls -al is another file. Seems like filesystems is being corrupted.

How can I delete 7,6 G file?
Is this dangerous? Is there any another action that I shoud do?

Thanks in advance
Ruben Rubio Rey

is that a typo or is there a space in the permission field?

What does xfs_check say? Which (linux?-)kernel are you using? If you are about to xfs_*, please make sure you have the *latest* xfsprogs[0], which is 2.8.10-1 right now...

I did't run xfs_check yet. I have to disconnect the server because I have to unmount the filesystem in orden to run the program (I ll do it after holidays if there is not risk).

I think I have found the response.
lastlog is a special "sparse file".

When du -sh command is executed, the space that shows is unreal. ls -al shows the good one disk usage.

Then, all seems is normal.

Thanks anyway!
