[1/2] git commit: updated refs/heads/4.4 to 97623bb
Repository: cloudstack
Updated Branches:
refs/heads/4.4 a79fd8816 -> 97623bb0d
reboot much faster in case of storage failure
When storage cannot be reached, it does not make sense to reboot as it will try to flush buffers, umount NFS mounts, etc. This will not work and thus cause a long delay. With this change, the box will reboot immediately (like pressing the reset button).

[2/2] git commit: updated refs/heads/4.4 to 97623bb
Posted by da...@apache.org.
write logfile just before rebooting the host
As discussed with @wido @pyr and @nuxro added an extra log line.
Tested it and it logs fine (tested to local disk) when syncing first:
Apr 3 15:31:23 mcctest2 heartbeat: kvmheartbeat.sh system because it was unable to write the heartbeat to the storage
By the way, it did also log to the agent.log but this extra log has the benefit of ending up in the system log so you'll probably find it easier there. Existing logs:

2015-04-03 15:31:23,950 WARN [kvm.resource.KVMHAMonitor] (Thread-24:null) write heartbeat failed: timeout; reboot the host
This closes #145
