ganeti.opcodes.OpGroupVerifyDisks

class documentation

class OpGroupVerifyDisks(OpCode):

Verifies the status of all disks in a node group.

Result: a tuple of three elements:

dict of node names with issues (values: error msg)
list of instances with degraded disks (that should be activated)
dict of instances with missing logical volumes (values: (node, vol) pairs with details about the missing volumes)

In normal operation, all lists should be empty. A non-empty instance list (3rd element of the result) is still ok (errors were fixed) but non-empty node list means some node is down, and probably there are unfixable drbd errors.

Note that only instances that are drbd-based are taken into consideration. This might need to be revisited in the future.

Constant	`OP_DSC_FIELD`	Undocumented
Constant	`OP_PARAMS`	Undocumented
Constant	`OP_RESULT`	Undocumented

Inherited from OpCode:

Class Method	`LoadOpCode`	Generic load opcode method.
Method	`__getstate__`	Specialized getstate for opcodes.
Method	`Summary`	Generates a summary description of this opcode.
Method	`TinySummary`	Generates a compact summary description of the opcode.
Constant	`WITH_LU`	Boolean that specifies whether this should be included in mcpu's dispatch table
Class Variable	`OP_DSC_FORMATTER`	A callable that should format the OP_DSC_FIELD; if not present, then the field will be simply converted to string
Class Variable	`OP_ID`	The ID of this opcode. This should be unique amongst all children of this class.
Instance Variable	`dry_run`	Whether the LU should be run in dry-run mode, i.e. just the check steps
Instance Variable	`priority`	Opcode priority for queue

Inherited from BaseOpCode (via OpCode):

Class Method	`GetAllParams`	Compute list of all parameters for an opcode.
Method	`__init__`	Constructor for BaseOpCode.
Method	`__setstate__`	Generic unserializer.
Method	`Validate`	Validate opcode parameters, optionally setting default values.

Inherited from ValidatedSlots (via OpCode, BaseOpCode):

Class Method	`GetAllSlots`	Compute the list of all declared slots for a class.
Class Variable	`__slots__`	Undocumented
