Here is the full log, including the stack for the exception, that we get at the
2 hour mark. as for the migratewait it is set to 36000 which should be 10
hours.

Subject: [Questionable] Re: [Questionable] Re: Timeout with live migration
Now I understand what you are doing, I am familiar with that concept (live
migration of VM within a cluster, having the VHD being moved from one SR to
another).
I just got confused when I read live migration of volumes (a volume does
not run by itself, so that why I asked a little for some more information).
Looking at the source code this is the variable used to control the timeout:
"long timeout = (_migratewait) * 1000L;"
The value of "_migratewait" is taken from this parameter:
value = (String) params.get("migratewait");
_migratewait = NumbersUtil.parseInt(value, 3600);
Therefore, the name of the parameter to be configured is "migratewait", the
default value is 3600.
BTW1: I think that is a terrible parameter name. We should refactor that,
could you open a Jira ticket for that?
BTW2: that error message you posted does not seem to be related to the
migration timeout; hence, in the code if the copy times out the message
would be:
"Async " + timeout/1000 + " seconds timeout for task " + task.toString()"
Maybe because it throws a "Types.BadAsyncResult(msg)" and that might be
translated into that message, or that might not be related to the problem
itself, and you just thought that it was.
Does it help you?
