HA in CS 4.1
Can someone "explain like I'm 5" how HA in CS should work? I have 4.1 setup
with XCP hosts. To simulate a host failure, I've hard powered off a host
through iDRAC and CS doesn't seem to know about it, at all -- the instances
still show as running, but I cannot connect to them, and the host shows as
up in the infrastructure section.
The instances, including the SSVM, that were on there are "gone" and have
not been restarted on any of the other hosts.

Hi Kirk,
alert.wait definitely works for XenServer Hosts as we have used this in various acceptance test sessions.
I know this does not help you, but at least you know the setting is good, and something else must be causing the failure to HA.

I set alert.wait to 60sec, restarted, shut down host, and nothing :-(

Re: HA in CS 4.1
Posted by Bryan Whitehead <dr...@megahappy.net>.
There should be a big red all caps message on the download page and in
the docs explaining the HA is completely broken and nonfunctional for
KVM users on 4.1.0.
There is no way I'd have updated to 4.1.0 if I had caught this
earlier, once I get the time I'll likely downgrade back to 4.0.2
(Assuming it works in that).

Well, we're not going to hold off on 4.1.1 honestly. And I raised it to
get further input on the issue, specifically thinking about how to get some
thoughts pulled together for scope and possible release timing.

Sounds like https://issues.apache.org/jira/browse/CLOUDSTACK-3535 then.
It's been upgraded to a blocker now so 4.1.1 and 4.2 can't be released until it's fixed. I hope you can get involved in testing the fix.

Hi Kirk,
I've seen this behaviour with KVM (I filed bug CloudStack-3535) but we've found XenServer works fine.
There is a global setting (alert.wait) which is blank by default. This is the number of seconds CloudStack waits after it loses communication a host before doing anything. Blank somehow equals 30 mins in this case.

Re: HA in CS 4.1
Posted by Salvatore Sciacco <sc...@iperweb.com>.
I've powered off a host of a KVM cluster to simulate the server failure and
I'm experiencing the "Agent state cannot be determined, do nothing" loop.
How I can tell the manager that the host is died and to start the HA
procedure? There is some field on the db I can update?

Re: HA in CS 4.1
Posted by Ryan Lei <ry...@cht.com.tw>.
FYR, I have done some similar tests several weeks ago to test the host HA
functionality.
CS 4.0.2 + XenServer 6.0.2: Works as expected. HA-enabled VMs (including
System VMs) were automatically restarted on HA-dedicated hosts.
CS 4.1.0 + XCP 1.6: No HA thing happened at all much like what you
described. The states of VMs and hosts were just like before, but
inaccessible. CloudStack just couldn't seem to detect the host down!
CS 4.1.1 (git) + XenServer 6.1: Works as expected. Just like the first case.
I didn't have time to try other combinations, and the logs are gone, but I
guess the problem more likely has to to with XCP support than CS 4.1.0.
