Description Rami Vaknin 2012-06-18 04:41:21 EDT
sanlock 2.3.1

wdmd service fails to start if it can find a watchdog device, hence sanlock service fails to start too since wdmd is its dependency.

It will be best to load the softdog module in case there is no loaded watchdog driver, as a dependency for wdmd service.

From /var/log/messages:
Jun 13 17:44:06 localhost sanlock[2682]: 2012-06-13 17:44:06+0300 112156 [2682]: wdmd connect failed for watchdog handling

Comment 8 Douglas Schilling Landgraf 2012-07-27 15:16:50 EDT
Sorry, I must say that I am using Fedora 17 (oVirt Node), do we have a bugzilla for fedora ?
Should I open a bz for Fedora?

Comment 9 David Teigland 2012-07-27 15:18:26 EDT
f17 is sanlock-2.4-2.fc17

rhel6 is sanlock-2.3-3.el6_3

Thanks David!

Verified on RHEL6.3 with sanlock-2.5-1.el6.x86_64

I rmmod the softdog kernel module after stopping sanlock and wdmd services. The softdog kernel module was loaded automatically while stating the wdmd service.
Comment 13 Leonid Natapov 2012-12-17 09:59:26 EST
sanlock-2.6-2.el6.x86_64 same behavior as 2.5-1.
