I believe Andreas is right &amp; you have it left there from an old version. did you maybe not rpm --erase old rpms before rpm installing new ones?</p> <p>Yes, this seems to be created as part of the LLNL install, the modules are all links. <br/> lrwxrwxrwx 1 root root 79 Nov 6 14:56 lvfs.ko -&gt; /lib/modules/2.6.32-431.29.2.1chaos.ch5.2.x86_64/extra/kernel/fs/lustre/lvfs.ko</p> Development Rank 1|hzx0gf: Rank (Obsolete) 16447 Severity
