| | * LCP IP allocation algorithm - new function lcp2_failback_candidate()Martin Schwenke2011-11-011-48/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a bug in LCP2. Selecting the node with the highest imbalance doesn't always work. Some nodes can have a high imbalance metric because they have a lot of IPs. However, these nodes can be part of a group that is perfectly balanced. Nodes in another group with less IPs might actually be imbalanced. Factor out the code from lcp2_failback() that actually takes a node and decides which address should be moved to which node. This is the first step in fixing the above bug. Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit 75718c5768b5bb5c0bcd7dd90e0327c6ed22a63d)

| | * | RB_TREE: Add mechanism to abort a traverseRonnie Sahlberg2011-11-088-48/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the callback signature for traversal functions to allow a client to abort a traverse before it finishes. Updates to all callers and examples as well as rb-test tool. (This used to be ctdb commit 8ab0c63ad36cfbbb1e5fed46a1f4c47b1fdb581f)

| | * | ReadOnly: If record does not exist, upgrade to write-lockRonnie Sahlberg2011-10-281-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we attempt a readonly lock request for a record that do not exist (yet) in the local TDB, then upgrade the request to ask for a write lock and force a request for migrate the record onto the local node. This allows the "only request record on second local request for known contended records" heuristics to try to avoid creating readonly delegations unless we have good reason to assume it is a contended record.

With 40 or 50 invocations of onnode this takes a long time. 2 changes to work around this: * If EXTRA_SSH_OPTS (which is passed to ssh by onnode) does not contains a ConnectTimeout= setting then add a setting for a 5 second timeout. * Filter the nodes before starting any diagnosis, taking out any "bad nodes" that are uncontactable via onnode. In the nodes summary at the beginning of the output, print information about any "bad nodes".
