I just upgraded my lustre version from 1.8.1.1 to 1.8.4 and I can't reboot my lustre clients cleanly anymore. I am using the latest RHEL kernel and
the openibd that comes part of that RHEL kernel + patchless lustre client installed from the tar ball.
The lustre client gets unmounted cleanly but the system deadlocks once the openibd driver is removed. I had to modify the openibd stop script to
include "umount lustre" and "lustre_rmmod" as a work around.
The following is the error message that I get when I try to reboot the lustre client:
