rm -rf not working on AIX 6.1

Hi Guys,

I have never seen this happen before, but created a directory as a user when installing some software, software install fails so I try and remove the directory as root and get an error. There is no processes using the folder see output:

ls -l

Could it be your directory is on a NFS mounted file system?

Yes thank you I cant believe I didnt notice that using an IBM loan box didnt think they would give us our storage on a non-posix file system!
