Yes. As a matter of fact, you have anticipated a question I have: how
does one re-build Lustre in a safe and consistent manner? I'm working
through the docs, but I have come across a problem when I try to run
"make rpms" in the Lustre source:<br>
<br>
make[4]: *** No rule to make target
`/usr/src/redhat/BUILD/lustre-1.6.5.1/ldiskfs/Module.symvers', needed
by `Module.symvers'. Stop.<br>
<br>
How do I ensure that the build environment that Lustre requires is
properly prepared? I could just hoick a soft link to the Module.symvers
file in the kernel tree, but that's a little messy.<br>
<br>
I've attached a draft copy of the build process to this message. Again,
just looking to sanity check the method, since I'm obviously missing
something.<br>
<br>
I'm going to rebuild the servers today so that I can provide the debug
information that Brian requested.<br>
