We are running a CloudStack environment with multiple XenServer hypervisors. This morning, one of our XenServers filled /var and was not longer connected to CloudStack. We corrected this problem and then needed to do an emergency network restart because the HV lost its networking info (believe this is a XenServer bug). By this time CloudStack had already migrated our VM's to other HV's. Once the emergency network restart completed, the host rebooted and came back up. Through the xe command set I can see it is connected to the other HV's in the pool, however when I go into Cloudstack and check on the host in the Infrastructure tab, it still lists as down. When I use the Force Reconnect button on it, it hangs indefinitely and memory usage eventually crashes the whole Cloudstack instance.
We are trying to find a way to get this HV reconnected back to Cloudstack. Idea's? William Clark
