Method Details [hide private]

__init__(self)
(Constructor)

source code 

Constructor.

Overrides: object.__init__

ParseOptions(self)

source code 

Parses the command line options.

In case of command line errors, it will show the usage and exit the program.

BurnCreateInstances(self)

source code 

Create the given instances.

Decorators:
  • @_DoCheckInstances
  • @_DoBatch(False)

BurnModifyRuntimeMemory(self)

source code 

Alter the runtime memory.

Decorators:
  • @_DoBatch(False)

BurnGrowDisks(self)

source code 

Grow both the os and the swap disks by the requested amount, if any.

Decorators:
  • @_DoBatch(False)

BurnReplaceDisks1D8(self)

source code 

Replace disks on primary and secondary for drbd8.

Decorators:
  • @_DoBatch(True)

BurnReplaceDisks2(self)

source code 

Replace secondary node.

Decorators:
  • @_DoBatch(True)

BurnFailover(self)

source code 

Failover the instances.

Decorators:
  • @_DoCheckInstances
  • @_DoBatch(False)

BurnMove(self)

source code 

Move the instances.

Decorators:
  • @_DoCheckInstances
  • @_DoBatch(False)

BurnMigrate(self)

source code 

Migrate the instances.

Decorators:
  • @_DoBatch(False)

BurnImportExport(self)

source code 

Export the instance, delete it, and import it back.

Decorators:
  • @_DoCheckInstances
  • @_DoBatch(False)

BurnStopStart(self)

source code 

Stop/start the instances.

Decorators:
  • @_DoCheckInstances
  • @_DoBatch(True)

BurnRemove(self)

source code 

Remove the instances.

Decorators:
  • @_DoBatch(False)

BurnRename(self, name_check, ip_check)

source code 

Rename the instances.

Note that this function will not execute in parallel, since we only have one target for rename.

BurnReinstall(self)

source code 

Reinstall the instances.

Decorators:
  • @_DoCheckInstances
  • @_DoBatch(True)

BurnReboot(self)

source code 

Reboot the instances.

Decorators:
  • @_DoCheckInstances
  • @_DoBatch(True)

BurnRenameSame(self, name_check, ip_check)

source code 

Rename the instances to their own name.

Decorators:
  • @_DoCheckInstances
  • @_DoBatch(True)

BurnActivateDisks(self)

source code 

Activate and deactivate disks of the instances.

Decorators:
  • @_DoCheckInstances
  • @_DoBatch(True)

BurnAddRemoveNICs(self)

source code 

Add, change and remove an extra NIC for the instances.

Decorators:
  • @_DoBatch(False)

BurnConfd(self)

source code 

Run confd queries for our instances.

The following confd queries are tested:

  • CONFD_REQ_PING: simple ping
  • CONFD_REQ_CLUSTER_MASTER: cluster master
  • CONFD_REQ_NODE_ROLE_BYNAME: node role, for the master

BurnAddDisks(self)

source code 

Add an extra disk to every instance and then detach it.

Decorators:
  • @_DoCheckInstances
  • @_DoBatch(False)

BurnRemoveDisks(self)

source code 

Attach a previously detached disk to an instance and then remove it.

Decorators:
  • @_DoCheckInstances
  • @_DoBatch(False)

_CheckInstanceAlive(self, instance)

source code 

Check if an instance is alive by doing http checks.

This will try to retrieve the url on the instance /hostname.txt and check that it contains the hostname of the instance. In case we get ECONNREFUSED, we retry up to the net timeout seconds, for any other error we abort.

BurninCluster(self)

source code 

Test a cluster intensively.

This will create instances and then start/stop/failover them. It is safe for existing instances but could impact performance.
