Hello,
I am running DRBD 8.4.2 on a pair of Centos6 hosts. When I start DRBD on
either of these hosts while running kernel version
2.6.32-279.19.1.el6.i686, the system will panic and display the below error
messages. DRBD runs normally on these systems with kernel versions
2.6.32-279.5.2.el6.i686 and lower.
Strangely, I have a different pair of servers running DRBD 8.4.2 without
problem using kernel version 2.6.32-279.19.1.el6.x86_64.
Any thoughts?
Thanks!
-Ryan
