I have a deployment server, and I get that apps defined in the serverclass.conf will be removed or deployed based on the machines listed in the serverclass.conf white and blacklists. But I'm seeing inconsistencies regarding apps that aren't defined on the serverclass / deployment server being removed (or not) on the client side.
Example - I have 3 serverclass + apps defined on the serverclass.conf. outputs, which goes to everyone, ta_windows which goes to windows machines and ta_linux which goes to linux boxes. The linux boxes also have a custom apps locally configured named varlogs. Varlogs has never been added or defined to the deployment server. When I hook a new linux box that has varlogs on it to the deployment server, varlogs vanishes. However, some of the linux boxes also have a custom app named sri, and that /doesn't/ vanish even though it also isn't defined in serverclass.
What's the appropriate behavior? Should hooking up to a deployment server wipe the installed apps down to what the deployment server is trying to send them or not? And if it is supposed to reset to nothing but things defined in serverclass, is there a way to not have that happen? We'd like to let folks keep their customized apps if possible.
Deployment Server deployes or removes apps based on the serverclasses.conf file.
This means that if you have an app non listed in serverclasses.conf, it will be removed from a server managed by DS.
I don't know why (if you want, we could debug it!) the sri app is in a server (managed by DS) and it isn't listed in serverclasses.conf that's still in the server.
Anyway the rule is:
if a server is managed by DS, you have to manage all the apps in that server in serverclasses.conf, otherwise they will be removed.
Obviously we don't speak about Search Head Clusters and Indexers Clusters.
It looks like the linux team had a very old deployment server everyone had forgotten about, and the missing apps were the ones originally deployed by it. So when the new deployment server got involved, the clients evaluated their prexisting serverclass.xml, couldn't find the older apps, and promptly removed them. The reason only some apps were affected was because the newer ones had never been part of the old deployment.
We wiped the out of date serverclass.xml before hooking into the new server, and things went as expected - by which I mean the apps defined in the serverclass.conf on the deployment server were added or removed as based on their stanza, and anything not defined in the serverclass.conf were left alone and not removed or changed.
good! please accept the answer fo the other people of the Community.
Ciao and Next time.
