RPC call_node_info: change protocol
Currently, the call_node_info RPC does always check both the VG freespace and the hypervisor information. However, in ⅔ of the uses, we onlycare about one or the other. Therefore, we change it so that if any ofthe passed parameters is None, we don't perform the respective check. We...
Cluster rename: skip offline nodes

Fix per-vg checks in instance disk conversion

This is needed to at least see the current group configuration.
Fix disk checks in “gnt-cluster verify”
Tests have shown that the changes in commit b8d26c6e5 don't work aswanted. If any disk wasn't found on the node, all disks located on thesame node would show as faulty. The cause was incorrect exceptionhandling on the node....

Yet another rework in LUSetNodeParms
We will need the new role in CheckPrereq, so move its computation thereand save the new role to self.
Prevent moving/creating instances on non-vm nodes
This small patch modifies LUCreateInstance, LUReplaceDisks andLUMoveInstance to not use non-vm_capable nodes.
Add vm_capable to LUSetNodeParams
And also do some cleanup: we only run the role changed actions if thenode has actually changed roles.
Add support for vm_capable in cluster verify
The method to make vm_capable integrate easily into cluster verify is as follows:
- we add a new NV_VMNODES that represents nonvm-capable nodes the LU populates this list (it's expected that non-vm_capable nodes...

LUClusterVerify: Complain if disk is marked faulty
This will show a warning if, for example, one side of a DRBDdisk becomes unavailable. The data is collected separatelyfrom the other verification data.
Example output:

Add the master/vm_capable flags to objects
This adds the flag and some initial handling. The rest of the changes,for cmdlib, come in a separate patch.

There have been many bugs in gnt-node modify. Let's try to introducesome more.
