Wow, that's quite old.
It's pacemaker provided by ubuntu 12.04.

Should I stop sbd daemon even if I have stonith-enabled=false?
stonith-enabled="false" does not disable sbd's self-fencing in case of
lost devices. (I think I'd be willing to take a patch if it isn't too
convoluted.)
My cluster's nodes are in vmware vsphere virtual machines. Could I use
another stonith device, like external/vcenter? Is there any
recommendation about it?
You may want to consider using the -P option to enable pacemaker
integration though; that could also make things better.
Is this a sbd's option? I can't see that options (or it is
undocumented):
amateo_adm@myotis51:/var/log$ sbd --help
sbd: invalid option -- '-'
Shared storage fencing tool.
Syntax:
sbd <options> <command> <cmdarguments>
Options:
-d <devname> Block device to use (mandatory; can be specified up to 3
times)
-h Display this help.
-n <node> Set local node name; defaults to uname -n (optional)
-R Do NOT enable realtime priority (debugging only)
-W Use watchdog (recommended) (watch only)
-w <dev> Specify watchdog device (optional) (watch only)
-T Do NOT initialize the watchdog timeout (watch only)
-v Enable some verbose debug logging (optional)
-1 <N> Set watchdog timeout to N seconds (optional, create only)
-2 <N> Set slot allocation timeout to N seconds (optional, create
only)
-3 <N> Set daemon loop timeout to N seconds (optional, create only)
-4 <N> Set msgwait timeout to N seconds (optional, create only)
-5 <N> Warn if loop latency exceeds threshold (optional, watch only)
(default is 3, set to 0 to disable)
-t <N> Interval in seconds for automatic child restarts (optional)
(default is 3600, set to 0 to disable)
Commands:
create initialize N slots on <dev> - OVERWRITES DEVICE!
list List all allocated slots on device, and messages.
dump Dump meta-data header from device.
watch Loop forever, monitoring own slot
allocate <node>
Allocate a slot for node (optional)
message <node> (test|reset|off|clear|exit)
Writes the specified message to node's slot.
Note that not running the sbd daemon and setting stonith-enabled="true"
again will yield false STONITH successes. You're really not encouraged
to do that, or only very carefully.
Yes, I know it. I had stonith disabled (but sbd was running) because
I'm having latency problems with my fiber channel disks, so I wanted to
debug them without unnecessary reboots.
