Description

We have exported the lustre filesystem over nfs from one of the lustre clients(say c1). We mount
the nfs filesystem on another node(say n1). On the node n1, we create a executable script file(f1).
We make a copy of this file f1 to f1.cpy. These files run on the nodes n1 as well as c1. But on
other lustre clients, which have the lustre file system mounted, the script file f1.cpy does not
execute where as the file f1 does.

The following is the error message we get when we try the above.

[root@sfsclient8 testfs]# ./hi_world_copy
./hi_world_copy: Text file busy

The same problem will occur if this is compiled binary as well.
