Hi,

I have solved my problem.

I find a little problem in the script ‘/usr/lib64/stonith/plugins/external/sbd’ when it retrieve the hosts list.

I substitute this lines:

 

nodes=$(

if is_heartbeat; then

    crm_node -H -p

else

    crm_node -p

fi)

 

Whit these:

 

if is_heartbeat; then

    nodes=$(crm_node -H -p)

else

    nodes=$(crm_node -p)

fi

 

and now the resource ‘external/sbd’ function very well.

 

 

 

Best regards, Nicola.

The response to a query

/usr/sbin/sbd -d /dev/mapper/mpath1p1 list

is

0       clover-a.rsr.rupar.puglia.it    clear

1       clover-h.rsr.rupar.puglia.it    clear

 

 

Ciao, Nicola.

FWIW, here's my setup for sbd on shared storage:

in /etc/init.d/boot.local:
sbd -d /dev/disk/by-id/dm-uuid-part2-mpath-3600a0b8000266f7e000035414bd00428 -D -W watch

xenhost1:~ # sbd -d /dev/disk/by-id/dm-uuid-part2-mpath-3600a0b8000266f7e000035414bd00428 list
0       xenhost1        clear
1       xenhost2        clear

excerpt from 'crm configure show':
primitive sbd stonith:external/sbd \
        operations $id="sbd-operations" \
        op monitor interval="15" timeout="15" start-delay="15" \
        params sbd_device="/dev/disk/by-id/dm-uuid-part2-mpath-3600a0b8000266f7e000035414bd00428"
clone sbd-clone sbd \
        meta interleave="true"

What do you see if you run '/usr/sbin/sbd -d /dev/mapper/mpath1p1 list'?

Also, it is needed to add stonith to cib:

crm configure primitive sbd_stonith stonith:external/sbd meta target-role="Started" op monitor interval="15" timeout="15" start-delay="15" params sbd_device="/dev/sda1"


Dne 29.4.2010 15:46, Nicola Sabatelli napsal(a): 

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.

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:
