 New Comment:

We recently upgraded our underlying Linux OS and ran into this same issue.  For 
other Googlers who come across this bug report:  Use the "noserverino" mount 
option as specified by others.

If you want to know more about this issue, see: 
http://linux.die.net/man/8/mount.cifs

The important thing to know is that CIFS servers will frequently return inode 
integer values that are greater than 31^2. If you read the PHP documentation for 
these filesystem functions, you will find a disclaimer that these large unsigned 
integer values will break in PHP.

Disable the possibility of really big inode numbers from your CIFS mounts by 
using the "noserverino" mount option.

Same issue. Windows Seven 32 bit. When programming a file manager i found that some dirs were being
listed as files. For some reason when i create a new dir it gets listed correctly but when i COPY it
from somewhere it is listed as a file.

Cannot reproduce, still works fine here.

When you edit your report, please re-open it, too.

The mount command lacks noserverino:

$ tail -n 1 /etc/fstab
//theword/d  /mnt/theword  cifs   
nocase,file_mode=0664,dir_mode=0775,username=Administrator%,uid=nobody 0 0

How does the mount command look like, so that it fails?

Mike,

Using the 'noserverino' workaround does mitigate the problem, but it does not address the
underlying issue.
