Expand description
Quorum provides basic information about the quorate state of the cluster with callbacks when nodelists change.
Structs§
- Handle
- A handle into the quorum library. Returned from initialize and needed for all other calls
- Model1
Data - Data for model1 initialize
- RingId
- RingId returned in quorum_notification_fn
Enums§
- Model1
Flags - Flags for initialize, none currently supported
- Model
Data - Data for model1 initialize
- Quorum
Type - Value returned from initialize. Indicates whether quorum is currently active on this cluster.
Functions§
- context_
get - Get the current ‘context’ value for this handle. The context value is an arbitrary value that is always passed back to callbacks to help identify the source
- context_
set - Set the current ‘context’ value for this handle. The context value is an arbitrary value that is always passed back to callbacks to help identify the source. Normally this is set in initialize, but this allows it to be changed
- dispatch
- Display any/all active QUORUM callbacks for this Handle, see DispatchFlags for details
- fd_get
- Return a file descriptor to use for poll/select on the QUORUM handle
- finalize
- Finish with a connection to corosync
- getquorate
- Return the quorate status of the cluster
- initialize
- Initialize a connection to the quorum library. You must call this before doing anything else and use the passed back Handle. Remember to free the handle using finalize when finished.
- trackstart
- Track node and quorum changes
- trackstop
- Stop tracking node and quorum changes
