|
Returns list of checked and expanded node names.
|
Returns list of checked and expanded instance names.
|
Return the new version of a parameter dictionary.
|
Checks whether all selected fields are valid.
|
Validates that given hypervisor params are not global ones. This will ensure that instances don't get customised versions of global params. |
Ensure that a given node is online.
|
Ensure that a given node is not drained.
|
Ensure that a given node is vm capable.
|
Ensure that a node supports a given OS.
|
Ensure that a node has the given secondary ip.
|
Checks that file storage is enabled.
|
Expand an item name.
|
Builds instance related env variables for hooks This builds the hook environment from individual variables.
|
Build a list of nic information tuples. This list is suitable to be passed to _BuildInstanceHookEnv or as a return value in LUQueryInstanceData.
|
Builds instance related env variables for hooks from an object.
|
Check whether an OS name conforms to the os variants specification.
|
Check the sanity of iallocator and node arguments and use the cluster-wide iallocator if appropriate. Check that at most one of (iallocator, node) is specified. If none is specified, then the LU's opcode's iallocator slot is filled with the cluster-wide default iallocator.
|
Verifies a certificate for LUVerifyCluster.
|
Distribute additional files which are part of the cluster configuration. ConfigWriter takes care of distributing the config and ssconf files, but there are more files which should be distributed to all nodes. This function makes sure those are copied.
|
Check that mirrors are not degraded. The ldisk parameter, if True, will change the test from the is_degraded attribute (which represents overall non-ok status for the device(s)) to the ldisk (representing the local storage status). |
Prepare the block devices for an instance. This sets up the block devices on all nodes.
|
Shutdown block devices of an instance. This function checks if an instance is running, before calling _ShutdownInstanceDisks. |
Return the instance disks selected by the disks list
|
Shutdown block devices of an instance. This does the shutdown on all nodes of the instance. If the ignore_primary is false, errors on the primary node are ignored. |
Checks if a node has enough free memory. This function check if a given node has the needed amount of free memory. In case the node has less memory or we cannot get the information from the node, this function raise an OpPrereqError exception.
|
Checks if nodes have enough free disk space in the default VG. This function check if all given nodes have the needed amount of free disk. In case any node has less disk or we cannot get the information from the node, this function raise an OpPrereqError exception.
|
Create a tree of block devices on a given node. If this device type has to be created on secondaries, create it and all its children. If not, just recurse to children keeping the same 'force' value.
|
Create a single block device on a given node. This will not recurse over children of the device, so they must be created in advance.
|
Generate a suitable LV name. This will generate a logical volume name for the given instance. |
Calculates the ETA based on size written and total size.
|
Wipes instance disks.
|
Create all disks for an instance. This abstracts away some work from AddInstance.
|
Remove all disks for an instance. This abstracts away some work from `AddInstance()` and `RemoveInstance()`. Note that in case some of the devices couldn't be removed, the removal will continue with the other ones (compare with `_CreateDisks()`).
|
Hypervisor parameter validation. This function abstract the hypervisor parameter validation to be used in both instance create and instance modify.
|
OS parameters validation.
|
|
_POutputFieldsoutput fields for a query operation
|
_PShutdownTimeoutthe shutdown timeout
|
_PInstanceNamea required instance name (for single-instance LUs)
|
_PMigrationModethe migration type (live/non-live)
