Can't attach storage domain / Unsupported watchdog
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?
