Hello,
pacemaker does not start on this machine(Fujitsu PRIMERGY RX2540 M1)
with following error in the logs:
sbd: [13236]: ERROR: Cannot open watchdog device: /dev/watchdog: No such
file or directory
Does /dev/watchdog exist?
No
ls -l /dev/watch*
ls: cannot access /dev/watch*: No such file or directory
Then you probably don't have one at all.
Maybe no hardware,the driver is not loaded or e.g.
udev doesn't create the node for some reason.
For a test at least you can try loading loading softdog.
[kwenning@kwenning pacemaker]$ sudo modprobe softdog
[sudo] password for kwenning:
[kwenning@kwenning pacemaker]$ ls -l /dev/watchdog
crw-------. 1 root root 10, 130 Jan 3 13:39 /dev/watchdog
On the node where I am getting the sbd error, by loading the "softdog"
module helps fix the issue
Now the strange part.. this is happening on a single node only, i.e
only on a single
node we are getting the error:
sbd: ERROR: Cannot open watchdog device: /dev/watchdog: No such file or
directory
while on another node(100% identical, same OS/Software/configurations
and same Hardware) even though
/dev/watchdog is also missing there, but still pacemaker and sbd starts
there without any
error and without loading the "softdog" module.
If you have more than one watchdog device, you can configure
sbd to use a different device using the -w option.
Cheers,
Kristoffer
