I just installed Lustre and set-up two filesystems, one for home and another for /usr/local. Set-up was smooth, but I''ve ran into a problem. I can not execute files on /usr/local. I get an error that the app can not be found. I can ls the directory and it is there. The weird thing is that I can execute files from the /home filesystem. I''ve tried reformatting the ''local'' mdt and the ost, but still the same results. The system is Debian etch using the 2.6.16 SUSE kernel recompiled on Debian along with the SUSE lustre packages recompiled. Any thoughts as to the cause of my problems?

I answered my own question. Too many things were changing. It happened to be a problem with dynamic libraries. It just so happened that every file that I tried on home was static or a script and every file that I tried on local was dynamically linked.

Could you try stracing one of your dynamically-linked binaries (hopefully a simple one) and see what is failing?> On 5/8/07 7:49 PM, "Robert LeBlanc" <robert@leblancnet.us> wrote: > > > I just installed Lustre and set-up two filesystems, one for home and another > > for /usr/local.
