Hotplug: cmdlib support
Hotpluging is done by functions invoked by ApplyContainerMods(). Inorder hotpluging to take place the --hotplug option must be passedotherwise the modifications will take place after reboot.
NIC hotplug supports add, remove and modify. The modify is done by removing...
Opcodes: move storage type checks to cmdlib
So far, there was a static check whether or not a givenstorage type of an opcode was enabled. This check isno longer possibe at this layer, because the informationwhether or not file/shared file storage is enabled must...
cmdlib: remove usage of ENABLE_FILE_STORAGE
This patch removes all usages of the constant'ENABLE_FILE_STORAGE' from the cmdlib code andreplaces them by checking the cluster's configuration.

backend: remove ENABLE_FILE_STORAGE
This patch removes the usage of the ENABLE_FILE_STORAGEconstant in the backend code. To avoid having to passit through various RPC calls, we instead move the checkto cmdlib.

Unittesting for instance_storage._CheckNodesFreeDiskOnVG
This patch refactors the '_CheckNodesFreeDiskOnVG' ofcmdlib.instance_storage to make it at least a littlemore testible and provides the unit tests for it.
Fix propagation of storage parameters to/from backend
This patch fixes two problems with the storage reportingthat showed up in the QA for exclusive storage:
- The processing of storage space information for instance operations wrongly assumed that the volume group's...
Extend RPC call 'node_info' by storage parameters
This patch extends the actual RPC call to accept storageparameters with each storage units. It adjusts all codewhich performs this code by integrating the 'exclusivestorage' flag into the lvm storage unit....
Enable disk growth with exclusive storage
Disk growth is now supported also with exclusive storage, so we let theoperation continue.
Enable disk growth test in qa also with exclusive storage.

Add exclusive_storage to blockdev_grow RPC
The flag is passed to the RPC, but it's still ignored by noded.

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....
Add hvparams to RPC call 'node_info'
This patch adds the hvparams parameter to the RPC call'node_info'. It also adjusts the related code in noded.pyand Query/Node.hs

Use RpcResult.Warn where appropriate the cmdlib
To avoid repetitive code, make use of the functionality factoredout to the Warn method of RpcResult.

Export instance disk spindles
Instance disk spindles can be queried via LUXI and RAPI, and are exportedthrough the allocator interface. This is a prerequisite for htools tohandle spindles.
The length of a RAPI query including all the instance fields now has become...
Add disks_active to configuration
This flag tracks if the disks of an instace are supposed to be active.That's the case when an instance is running or when its disks gotactivated explicitly (and in a couple of other cases).It will be used by watcher to re-activate disks after a node reboot....
Spindles are mandatory with exclusive storage
If they are not specified in the command line an error is reported. Also,disk creation would fail without them.
QA has been updated.

New RPC to get size and spindles of disks
This RPC replaces the existing one that only returned disk size.

Add spindles field to disk object
The field is filled with the value provided on the command line.

Check that spindles are not given when they are not allowed
Masterd checks that specifications for new disks don't include spindleswhen exclusive storage is disabled.
Add "spindles" option to instance disk creation commands
The option is parsed but ignored, for the moment.
RPC 'node_info': <storage_type,key> instead of vg_names
This replaces the field 'vg_names' in the RPC call of 'node info' by'storage_units'. A storage unit is a tuple <storage_type,key>and a generalization of a vg_name. The list of vg names is replaced by...
