Subject: kdump: No udev events for memory hotplug?
Date: Wed, 26 Oct 2011 18:08:12 +0200 [thread overview]
Message-ID: <1319645292.3321.24.camel@br98xy6r> (raw)
Hello Vivek and Eric,
I noticed that on my system kernel 3.1 *no* udev events for memory
hotplug are generated. Same on my RHEL6.1.
# udevadm monitor
# echo offline > /sys/devices/system/memory/memory4/state
-> No event
But we need the udev events in order to do a kdump reload for setting up
the ELF loads correctly.
In my /etc/udev/rules.d/98-kexec.rules there are rules for memory
hotplug:
SUBSYSTEM=="memory", ACTION=="add", PROGRAM="/etc/init.d/kdump restart"
SUBSYSTEM=="memory", ACTION=="remove", PROGRAM="/etc/init.d/kdump
restart"
Perhaps/probably I am missing something?
Michael
