Is the drbd module loaded on the failing node ?
kmod-drbd82-8.2.6-2 contains the drbd.ko module (in
When you update your kernel, a /sbin/weak-modules script is called to
symlink the extras kmods from previous kernels to all install kernels.
So that means that in your actual
/lib/modules/2.6.18-92.1.22.el5/weak-updates/drbd82/ folder contains
symlinks to the original one.
It that the case ? have you manually deleted the old
/lib/modules/2.6.18-92.1.13.el5/ directory ?
