Hi, initially submitted here: https://bugzilla.redhat.com/show_bug.cgi?id=1442593 The node that crashed was at the time the active member of an active/passive Pacemaker cluster, using DRBD backed replicated storage for iSCSI and NFS resources. The RedHat developer closed the bug due to loading drbd out-of-tree. The module is built using the source from http://git.drbd.org/drbd-8.4.git/ Even though it may or may not be related to DRBD, I thought it's worth having your opinion on this. More details below. modinfo drbd filename: /lib/modules/3.10.0-514.16.1.el7.x86_64/weak-updates/drbd84/drbd.ko alias: block-major-147-* license: GPL version: 8.4.9-2 description: drbd - Distributed Replicated Block Device v8.4.9-2 author: Philipp Reisner <phil at linbit.com>, Lars Ellenberg <lars at linbit.com> rhelversion: 7.3 srcversion: F9BD1E13798E45BA4CA1B92 depends: libcrc32c vermagic: 3.10.0-514.10.2.el7.x86_64 SMP mod_unload modversions parm: minor_count:Approximate number of drbd devices (1-255) (uint) parm: disable_sendpage:bool parm: allow_oos:DONT USE!
