* Eventscripts: remove redundant firewall rules from 11.natgwMartin Schwenke2012-07-261-7/+0
| | | | | | | | | | | aeb70c7e7822854eb87873a5c7783e27e6e72318 said it moved these but it redundantly duplicated them instead. That commit also fixed the problem because it moved the rules after delete_all() not out of the startup event as claimed.

* Eventscripts - redesign and rewrite 13.per_ip_routingMartin Schwenke2012-03-221-398/+251
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current version is quite difficult to read. This one is hopefully clearer. Major changes: * The configuration file has a more forgiving syntax. Items can be separated by arbitrary whitespace. * Mappings between IP addresses and table IDs are no longer stored in files in a state directory. Instead they are stored in /etc/iproute2/rt_tables as mappings between table IDs and labels, as allowed by the ip command. The current structure of the labels is ctdb.<source-ip>. This means that once the labels are setup the routing tables can be referenced by just knowing the source IP. As with the old state directory, mappings in this file owned by CTDB are deleted when CTDB shuts down. * There are no release or re-add scripts. - Release scripts are not necessary as an optimisation because of the previous improvement (i.e. use of rt_tables). No lookup is necessary to delete rules or flush tables. - Re-add scripts are no longer used. Routes can still go missing when removal of a primary IP from an interfaces (or similar) causes removal of all other addresses (i.e. secondaries) and also all associated routes. However, any missing routes are now re-added in the "ipreallocated" event. This happens shortly after takeip/releaseip/updateip and means that the routes will only be re-added once. The window for missing routes is slightly bigger but is not expected to be significant. * The magic "__auto_link_local__" configuration value no longer causes a dynamic configuration file to be maintained in a state directory. The link local configuration is now generated when needed from the public_addresses file. This greatly simplifies the code. This approach is slightly less efficient but should not be significant. The above changes mean that, apart from maintaining mappings in the rt_tables file, there are no state files kept anymore. Some utility functions only used by this script have been rewritten and moved into this script. They will be removed from the functions file by a future commit. The route re-add code will also be removed from interface_modify.sh by a future commit. It is currently harmless.

| | | | | | | | | | | | | | | | Print useful output and return a suitable exit code. The DISABLED and TIMEDOUT statuses use fake negative return codes, and these can't be faked from the shell. So we map DISABLED to OK and TIMEDOUT to ERROR - this should avoid nearly all surprises. When we do this we add a note to the beginning of the output. The alternative is to "fix" ctdbd to use only codes that can actually be returned by shell scripts. However, the reason for using negative codes is probably to distinguish them from real ones...

* Eventscripts: add a synchronous synthetic reconfigure event.Martin Schwenke2011-08-301-18/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the current code services can only be reconfigured asynchronously. This means that configuration file changes can be made, an asychronous reconfigure event can be triggered, and it always succeeds. Some time later when a service is actually reconfigured then a failure may be seen This adds a synthetic reconfigure event that reconfigures a service synchronously so that any failure is reported on exit. ctdb_service_check_reconfigure() is essentially reimplemented. If a reconfigure event is in flight and an ipreallocated or monitor event occurs then any scheduled asynchronous reconfigure is deferred until the next monitor cycle. This is to avoid reconfigures trampling on each other. In this case a monitor event will also replay the previous status to try to avoid exposing any temporary instability. If a reconfigure event collides with another reconfigure event it will exit with status 2, indicating that the reconfigure should be retried. The reconfigure event is implemented using a subprocess to control the exit from the synthetic event. As before, if a monitor event causes a scheduled synchronous reconfigure to occure then it will replay the previous status for the service, given that a reconfigure can cause temporary instability.

* Eventscripts: New configuration variable CTDB_SERVICE_AUTOSTARTSTOP.Martin Schwenke2011-08-302-0/+7
| | | | | | | | | | | | | | | | | | | Some of the current auto-start/stop logic is broken, particularly for Samba. Fixing it is non-trivial. If $CTDB_SERVICE_AUTOSTARTSTOP is "yes" then auto-start/stop services when told to newly manage or no longer manage them. This defaults to "yes". However, if using a canned configuration file that doesn't set $CTDB_SERVICE_AUTOSTARTSTOP then this stops the auto-start-stop logic from working. Therefore, this works around CQ S1026685 - on the system in question another daemon controls service auto-start/stop and CTDB just gets in the way.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split the netstat-specific parts of ctdb_check_tcp_ports() into new function ctdb_check_tcp_ports_netstat(). Implement new ctdb_check_tcp_ports_nmap() function that uses "nmap -PS" to check if the desired ports are listening. ctdb_check_ctdb_ports() now uses new configuration variable CTDB_TCP_PORT_CHECKERS to decide which port checkers to try. Default value is currently "nmap netstat". If nmap is not found then this will fall back to netstat - if logging is at debug level this will also fill the logs with message saying the nmap checker failed. This indicates that either nmap should be installed or the default value of CTDB_TCP_PORT_CHECKERS should be changed (in a configuration file) to avoid trying to use nmap.

| * Eventscripts - weaken TCP port check message if CTDB has just been started.Martin Schwenke2011-08-171-1/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes smbd and other services can take a while to start, especially when there is a lot of activity after ctdbd has just started. The TCP port check can then pollute the logs with lots of "ERROR" messages and possibly extra debug. This creates a flag file when a service is started (but not restarted) and this flag is removed the first time that TCP port checks succeed for that service. When a port check fails and the flag file still exists, a less extreme "INFO" message is printed rather than the usual "ERROR" message. This means that until the node actually becomes healthy we see more friendly messages. The subtext is that we're hearing false positive reports "recreates" of CQ S1024874 (samba stopped responding on port 445) quite often when ctdbd is started. This reduces the chances of people reporting such false recreates... Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit 571865eb6ef847857129d0b1e2ba5fa7254bfe8c)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ctdb_check_tcp_ports() runs "netstat -a -t -n" in a loop for each port. There are 2 problems with this: * Netstat is run on each loop iteration when it need only be run once. * The -a option is used to list all connections but the function only cares about the listening ports. There may be many thousands of non-listening ports to grep through. This changes ctdb_check_tcp_ports() to run netstat with the -l option instead of the -a option. It also only runs netstat once before the main loop. When a port is found to not be listening the output of the netstat command is now dumped to help with debugging.

| * Eventscripts: add a debug() function and call ctdb_set_current_debuglevel()Martin Schwenke2011-08-171-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The debug function passes its arguments to echo if $CTDB_CURRENT_DEBUGLEVEL is >= 4 (i.e. DEBUG). If no args are given then use stdin - this allows the function to be used with here documents. To ensure $CTDB_CURRENT_DEBUGLEVEL is set, ctdb_set_current_debuglevel() is called near the end of the functions file.
