RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Product Errata RHBA-2013:0530 0 normal SHIPPED_LIVE sanlock bug fix and enhancement update 2013-02-21 02:02:17 UTC

Description Rami Vaknin 2012-06-18 08:41:21 UTC 
Version:
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 19:16:50 UTC 
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?

Thanks
Douglas

Comment 12 Rami Vaknin 2012-11-08 15:20:38 UTC 
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 14:59:26 UTC 
sanlock-2.6-2.el6.x86_64 same behavior as 2.5-1.
