Add the ‘gnt-cluster verify-disks’ command
This patch adds the OpVerifyDisks handling in mcpu.py and theverify-disks command in the gnt-cluster script, which for every instancecomputed by LUVerifyDisks submits a new OpActivateInstanceDisks request.

Soften the requirements for hooks execution
Currently, an unreachable node (or one that return undetermined failure)in the hooks pre-phase will abort the curren operation. This is notgood, as a down node could prevent many operation on the cluster.
This patch changes a RPC-level failure (and not a hook execution...
Changes related to logging
This patch modifes: - mcpu.Processor.LogWarning to have its 'hint' parameter as optional and only log it if not None - cmdlib._WaitForSync to not log directly to stdout/stderr but via the proc.Log(Info|Warning) methods...
Add better error logging functions for LUs
Currently, some LUs use logger.Error, others just feedback_fn, etc. Thispatch adds three functions to mcpu.Processor than can be used to logmessages to both the log and to the user.
These function will be used to enhance the output of replace-disks for...
Implement tag searching
This patch adds a search command for locating tags on all objects of thecluster using a regex pattern.

Change the signature of some methods of mcpu.Processor
This patch moves the passing of the feedback_fn argument from the(Exec|Chain)OpCode to the initialization of the Processor instance.
Patch series for reboot feature, part 2
This patch series implements the reboot command for gnt-instance. Itsupports three types of reboot: soft (hypervisor reboot), hard (instanceconfig rebuild and reboot) and full (full instance shutdown and startupagain)....
Implement post-configuration-update hook
This patch adds a special hook: the post-configuration update hook. Thishook has only a post phase that runs after a top-level LU that modifiedthe configuration.
Since the hook is a post-phase one, no error checking is done on the...
Split the hooks env building in two parts
This patch moves some of the environment processing from _BuildEnv to anew _RunWrapper command which does the stringification and adds thesstore variables.
The reasoning is that the sstore can be fresher than before the...
Move hook execution decision to HooksMaster
Currently, the HooksMaster creation and execution decision is in theProcessor class. This is not optimal, so we change to always create ahooks master and instead make the decision inside that class, bycreating empty node lists for both pre and post if the lu doesn't...
Remove cfg and sstore parameters to HooksMaster
The HooksMaster class doesn't use the cfg parameter, and it's better touse it from the LU anyway (if needed). Let's remove it.
Also, the sstore of the LU can be fresher than the sstore we got at inittime, so use that instead and remove our own....
Remove the shebang from modules
Since modules are not directly executables, remove the shebang fromthem. This helps with lintian warnings.
Also make the autogenerated _autoconf.py contain two comment lines atthe beginning, like the other modules.

Change tags add/remove to process multiple tags
This patch changes the tags opcodes to work with multiple tags at onceinstead of only one. As such, the opcodes and some parameters arerenamed.
Implement cluster rename operation
This patch adds a new OpCode (and corresponding LU) that implements thecluster rename functionality.
This is done by shutting down the master role, making the needed sstoremodifications and distributing the changed files to all nodes, and then...
Implement instance rename operation
This patch adds support for instance rename operation at all remaininglayers: RPC, OpCode/LU and CLI.
Remove OpQueryNodeData and LUQueryNodeData
Now that LUQueryNodes supports all the functionality of LUQueryNodeData,let's migrate gnt-node.ShowNodeConfig to use it and remove all traces ofOpQueryNodeData and LUQueryNodeData.
Style changes for pep-8 and python-3000 compliance.
This changes the raising of exceptions from: raise Exception, valueto raise Exception(value)

The changes also involve a few cases of changing from raising standard...
Implement tag support for cluster, nodes and instances.
This is only the backend part, from the command line the tags can't beread/modified yet.
Move the cluster name from ConfigWriter to SimpleStore.
Reason: if left ConfigWriter, nodes don't know to which cluster they belong.This will bite us later when we'll revisit node join operation.
Cons: we lose the cluster name from the config file, which means a...

Big change/cleanup in relation to the master startup: - move the master node name from the ConfigWriter to SimpleStore (all nodes need this, and it was the only thing pulled in from the ConfigWriter on nodes) - fix mcpu.py and the testing w.r.t. this change; for testing, rename...
