Hi,

I have two servers in a drbd primary/secondary setup. Everything was fine until I had to reboot both servers.

The primary rebooted first, the secondary assumed fine, but when the (old primary) server got back online it was unable to mount the drbd fs complaining about the modules.

I've tried to find out the problem but the servers seem to have the same setup

rpm -qa | grep drbd drbd82-8.2.6-1.el5.centos kmod-drbd82-8.2.6-2

Kernel 2.6.18-92.1.22.el5 #1 SMP

Am I missing something?

thanks.

Is the drbd module loaded on the failing node ? kmod-drbd82-8.2.6-2 contains the drbd.ko module (in /lib/modules/2.6.18-92.1.13.el5/extra/drbd82/drbd.ko) 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 ?
