ssconf: add some more keys and some fixes
This patch adds the online node list and instance list to the ssconfkeys. In order to do distribute correctly the instance list, we need toupdate the cluster serial number on instance additions and removals.
The patch also changes the permissions on the ssconf files to be 0444:...
Implement lockless query operations
This patch adds the framework for, and enables lockless OpQueryInstances. Thismeans that instances will be shown in ERROR_up or ERROR_down state, even thoughthis is not an error (but just an in-progress job).
The framework is implemented as follows:...
Allow gnt-node evacuate to use an iallocator
This is a partial implementation of fully automated node evacuation:we allow passing an iallocator and all instance replace-disks will beexecute via that iallocator.
The individual OpReplaceDisks opcodes are submitted in a single job,...
Add gnt-node migrate
This is a (modified) forward-port of commit 1190 on the 1.2 branch:
This is the same as gnt-node failover, and is also a cut&paste of its code (almost). It will be really really useful to quickly empty a healthy node. I can be persuaded to merge MigrateNode and FailoverNode...
An attempt at fixing some encoding issues
This patch unifies the hardcoded re-encoding attempts into a singlefunction in utils.py. This function is used to take either an unicode orstr object and convert it to a ASCII-only str object which can be safely...
gnt-instance: support no_PARAMETER value
Since parameters get set to False if a no_ is prefixed don't try tointerpret those boolean values, and pass them unchanged.

gnt-instance list: accept input names
Currently gnt-instance list will refuse to take arguments, and alwaysreturn the full list of instances. This patch allows it to pass names toLUQueryInstances, so that we restrict the input to a given set ofinstances....
Check that instance exists before confirm. queries
Currently we ask the user for confirmation, and only after (try to)remove, failover or migrate the instance. This doesn't work nicely ifthe instance doesn't exist, so we make a query for the instance before...
Rework the multi-instance gnt commands
This patch changes the multi-instance gnt-* commands (gnt-instancestart/stop, gnt-node evacuate/failover) such that the individualoperations are submitted in parallel, ideally improving the speed of theexecution....
Sort the instance names in batcher
In case we submit multiple instances via batcher, it's nicer to have thesorted nicely.
