restrict the number of vcs service group starting up at the same time during hastart
hi,
is there any way to restrict the number of service groups that can be started during hastart? the service groups all have AutoStartList and there is no group dependency except the network interface is in its service group and other service groups access it via proxy.
Our problem is it seems that some of the application would fault because it didn't start within the default 60s during cluster startup (hastart). there is no resource dependency problem. as if i offline and online the service group, the service group would be ok again.
so i am thinking if the number of service groups to start up during (hastart) can be restricted, this problem should go away. or we can put some time delay in the config to do this perhaps?
Hi IdaWong,
There is no way to serialize the service group online without service group dependancies. However, you can lower the NumThreads for a given resource type to minimize the number of operations done for a given resource type. This would be handy if you have a large number of a single resource.
In your case, I would recommend increasing the OnlineRetryLimit for the resource that is having problems. This will tell VCS to attempt to online the resource a given number of times if it is not online after the online entry point completes. It might take some playing to get a value that works for you. I would start with either a value of 2 or 3 and see how that does. The default is 0.
Thank you,
Wally
