Hi,
I'm trying out some new boards (Intel Avotons), and it appears wdmd does
not like the watchdog device it provides.
Everything in oVirt 3.4.3 seems to run fine until it comes to adding a
storage device. It gives me an error about Cannot acquire host id
vdsm logs,
http://fpaste.org/122164/67695431/
# service wdmd start
(logs)
wdmd[14062]: wdmd started S0 H1 G0
wdmd[14062]: /dev/watchdog failed to set timeout
wdmd[14062]: /dev/watchdog disarmed
wdmd[14062]: no watchdog device, load a watchdog driver
# service wdmd status
wdmd dead but subsys locked
I can't seem to find any documentation on what wdmd does, could someone
explain?
Thanks,
Andrew

I was able to resolve this by disabling the HW watchdog model, and relying
on "softdog" eg.
blacklist iTCO_wdt
blacklist iTCO_vendor_support
Similar to, https://bugzilla.redhat.com/show_bug.cgi?id=878119
I guess it's more of the kernel not supporting it rather than an oVirt
issue.
What are the implications in this, based on the ovirt wiki wdmd is used as
sort of a fencing mechanism to reboot the host on failure. Wouldn't this
be considered redundant, considering power management exists also from the
ovirt-engine? Are there any downsides in using softdog?
