| * eventscripts: Fix statd-callout update handlingMartin Schwenke2013-05-283-31/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 60.nfs and 60.ganesha touch $statd_update_trigger every time they're run. This stops the statd-callout updates from ever being called. Make this logic self-contained and move it to new function nfs_statd_update() in the functions file. Call this in 60.nfs and 60.ganesha with the appropriate update period as the only argument.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Every time a node that wasn't the NAT gateway master gets reconfigured something like this appears in the log: ctdbd: 11.natgw: Failed to del 10.0.1.139 on dev eth1 Since this usually fails it is better to mute the error than to have it pollute the log.

| * recoverd: Backward compatibility for nodes without IPREALLOCATED controlMartin Schwenke2013-05-271-4/+103
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Consider the case of upgrading a cluster node by node, where some nodes are still running older versions of CTDB without the IPREALLOCATED control. If a "new" node takes over as recovery master and a failover occurs, then it will attempt to send IPREALLOCATED controls to all nodes. The "old" nodes will fail in a fairly nondescript way (result == -1). To try to handle this situation, fall back to the EVENTSCRIPT control to handle "ipreallocated". Only do this on the failed nodes. However, do not do this on nodes that timed out (they've probably implemented the control and we should call the regular fail_callback to get those nodes banned) or for stopped nodes (since they can't actually run the "ipreallocated" event via the EVENTSCRIPT control).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | If a tunable is not implemented on a remote node then this should not be fatal. In this case the takeover run can continue using benign defaults for the tunables. However, timeouts and any unexpected errors should be fatal. These should abort the takeover run because they can lead to unexpected IP movements.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds more serialisation to the startup, ensuring that the "startup" event runs after everything to do with the first recovery (including the "recovered" event). Given that it now takes longer to get to the "startup" state, the initscript needs to wait until ctdbd gets to "first_recovery".

| * tools/ctdb: "ctdb runstate" now accepts optional expected run state argumentsMartin Schwenke2013-05-244-4/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If one or more run states are specified then "ctdb runstate" succeeds only if ctdbd is in one of those run states. At the moment, if the "setup" event fails then the initscript succeeds but ctdbd exits almost immediately. This behaviour isn't very friendly. The initscript now waits until ctdbd is in "startup" or "running" run state via the use of "ctdb runstate startup running", meaning that ctdbd has successfully passed the "setup" event. The "setup" event code in 00.ctdb now waits until ctdbd is in the "setup" run state before proceeding via the use of "ctdb runstate setup".
