iallocator: get rid of MakeLegacyNodeInfo
So far, the iallocator makes a node info call, convertsthe result into a legacy node info structure and thenretrieves various values from it. This patch removesthe call to MakeLegacyNodeInfo completely, by letting the...
iallocator: factor out instance memory summation
The iallocator adjusts the free memory by a calculationof how much memory is actually currently used by instanceson the node. This calculation is rather complicated anddeserves its own function to increase testability. No...
iallocator: extract storage info directly from node info
So far, the iallocator made a node info RPC call, convertedthe result into a legacy node info format and then extractedthe storage information from that. This patch removes themiddle step of this procedure, skipping the legacy node info...
iallocator: computation of storage data
This patch extracts the processing of the storage-relateddata from the RPC call 'node_info' in a separate functionto increase testability. In addition, this patch containsunit tests for this function.

iallocator: factor out 'get_attr' method
This patch extracts an inline 'get_attr' method to extractdata from the result of the RPC call 'node_info'. It was sofar an inline function in the middle of a bigger method, which madethe code hard to read.
iallocator: prepare RPC call 'node_info'
This patch does a small refactoring in the allocator. It extractsthe preparation and actual call of the 'node_info' call into aseparate function. This is done for better testability. No functionalchanges otherwise....
Index instances by their UUID
No longer index instances by their name but by their UUID in the clusterconfig. This change changes large parts of the code, as the followingadjustments were necessary: * Change the index key to UUID in the configuration and the...
Refactor NodeInfo RPC regarding storage reporting
The NodeInfo RPC call is refactored to handle now more thanjust storage reporting for volume groups.
Since NodeInfo now returns storage space information notnecessarily for volume groups, but also for other storage...
Inline simple "alias" variables
Remove variables in the form "var = self.var" throughout all LU's. Those"alias" variables make it harder to read the code (it's no longerimmediately clear what's a field and what's a local variable), and canintroduce subtle bug (especially when not used consistently and when...
Index nodes by their UUID
No longer index nodes by their name but by their UUID in the clusterconfig. This change changes large parts of the code, as the followingadjustments were necessary: * Change the index key to UUID in the configuration and the ConfigWriter, including all methods....
