[Pacemaker] R: Stonith external/sbd problem

Thu Apr 29 13:46:12 UTC 2010

I have done exactly the configuration in the SBD_Fencing documentation.

That is:

/etc/sysconfig/sbd

SBD_DEVICE="/dev/mapper/mpath1p1"

SBD_OPTS="-W"

And I start the demon in this manner:

/usr/sbin/sbd -d /dev/mapper/mpath1p1 -D -W watch

Is correct?

Ciao, Nicola.

cat /etc/sysconfig/sbd

SBD_DEVICE="/dev/sda1"
SBD_OPTS="-W"

sbd -d /dev/shared_disk create
sbd -d /dev/shared_disk allocate your_machine

Oh, I forgot a piece: I had simular trouble until I actually properly
started sbd and then it worked.

I just set this up myself and it worked fine for me.

Did you follow the guide? You need to configure the sbd daemon to run on
bootup with appropriate options before external/sbd can use it.

I have a problem with STONITH plugin external/sbd.

I have configured the system in according to directive that I find at url
http://www.linux-ha.org/wiki/SBD_Fencing, and the device that I use is
configured with multipath software because this disk is residend on a
storage system.

I have create a resurse on my cluster using clove directive.

But when I try to start the resurse I have these errors:

from ha-log file:
