https://jira.whamcloud.com This file is an XML representation of an issue en-us 9.4.14 940014 05-12-2023 https://jira.whamcloud.com/browse/LU-146 Lustre <p>We have exported the lustre filesystem over nfs from one of the lustre clients(say c1). We mount<br/> the nfs filesystem on another node(say n1). On the node n1, we create a executable script file(f1).<br/> We make a copy of this file f1 to f1.cpy. These files run on the nodes n1 as well as c1. But on<br/> other lustre clients, which have the lustre file system mounted, the script file f1.cpy does not<br/> execute where as the file f1 does. </p> <p>The following is the error message we get when we try the above. </p> <p><span class="error">&#91;root@sfsclient8 testfs&#93;</span># ./hi_world_copy<br/> ./hi_world_copy: Text file busy</p> <p>The same problem will occur if this is compiled binary as well.</p> Use lustre as exported filesystem for NFSd.
