Hi, guys, I have learned Linux for a while now, but Linux is continuously surprising me with new stuffs nearly every day... Today I met a really strange problem, that the command "ls" indicates the size of some directories is ZERO, as for /home.

[root@localhost /]# ls -lh
drwxr-xr-x 2 root root 4.0K May 5 10:53 bin
drwxr-xr-x 4 root root 4.0K May 5 10:51 bio
drwxr-xr-x 4 root root 4.0K May 5 10:45 boot
drwxr-xr-x 4 root root 0 Jun 2 15:52 data
drwxr-xr-x 11 root root 4.0K May 20 21:36 dev
drwxr-xr-x 105 root root 12K Jun 2 15:52 etc
lrwxrwxrwx 1 root root 16 May 5 10:34 export -> state/partition1
drwxr-xr-x 3 root root 0 Jun 3 11:01 home


However, there is a directory inside /home, which contains many files/directories.

[root@localhost /]# ls -lh /home
total 4.0K
drwxr-xr-x 9 corona corona 4.0K Jun 3 11:03 corano

Even worst, when I tried to create a file under /home, I got the "permission denied" error,

[root@localhost home]# touch test
touch: cannot touch `test': Permission denied

By the way, /home is within the local file system, not NFS share. Can you guys provide any hint on this? Thanks

become the root user or use the "su" command and type this in

this will allow you to write in the file.



If i helped you at all please click the "thanks" button at the bottom right hand corner

Thanks for the suggestion. But it doesn't work,

[root@localhost /]# whoami
root
[root@localhost /]# ls -lsd home
0 drwxrwxrwx 3 root root 0 Jun 3 11:01 home
[root@localhost /]# touch /home/test
touch: cannot touch `/home/test': Permission denied

Try remounting the file system or rebooting.

did that work for you

Thanks, edwardcode, but it didn't work.

Would like to try, but cannot reboot right now. Any other suggestions? Thanks

Presuming the directories in question are mount points, what is the type of the file systems mounted there? df -T will display the types. And what is the output of the mount command (without any options or arguments)?
