* eventscripts: NFS RPC checks allows "nfsd" in addition to "knfsd"Martin Schwenke2013-05-061-1/+1
| | | | | | | | Want nfs_check_rpc_services() to support filenames without the 'k'. Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit d9775fcbd6e30eef8382bea68e2f9bad2309f2c1)
* eventscripts: New function nfs_check_rpc_services()Martin Schwenke2013-05-061-0/+29
| | | | | | | | | | | | | | This is intended to replace nfs_check_rpc_service(), which builds configuration into eventscripts. nfs_check_rpc_services() uses a directory of configuration checks that can be edited by an administrator. The files have one limit check and a set of actions per line. The program name is extracted from the file name.

| | | | | | | | | | | This reverts commit 92f74fd589467b46c758e116e97417edfe8773d7. This change is unused and is just complicating the function. Conflicts: config/functions (This used to be ctdb commit 77302dbfd85754e02559eccb2dd6c090db0b6b9f)

* eventscripts: Tweak the timeout check in kill_tcp_connections()Martin Schwenke2013-05-061-7/+13
| | | | | | | | | | | | | | This has 2 advantages: 1. It uses get_tcp_connections_for_ip() to check for leftover connections, instead of custom code. 2. It checks for the timeout condition before sleeping. The current code sleeps and then checks, so wastes a second.

* eventscripts: Simplify handling of $service name in "managed" functionsMartin Schwenke2013-05-061-6/+4
| | | | | | | | | | | | | | | | | | | | Complicated argument handling was introduced to deal with multiple services per eventscript. This was a failure and we split 50.samba. This simplifies several functions to use global $service_name unconditionally instead of having an optional argument. $service_name is no automatically longer set in the functions file. This means it needs to be explicitly set in 13.per_ip_routing because this script uses ctdb_service_check_reconfigure(). Eventscript unit test infrastructure needs to set $service_name during fake service setup, and policy routing tests need to be updated accordingly.

| | | | | | | | | | | | 5940a2494e9e43a83f2bca098bd04dfc1a8f2e93 makes script_log() always pass a message to logger, so script_log() can no longer log stdin.

* scripts: Ensure even external scripts get tagged in logs as "ctdbd"Martin Schwenke2013-04-221-2/+2

* eventscripts: Ensure directories are createdMartin Schwenke2013-04-221-0/+6

| | | | | | | | | | | | | | | | | | | The current logic is horrible and creates an unnecessary file. Let's make the script debug level independent of ctddb's debug level. * Have debug() use $CTDB_SCRIPT_DEBUGLEVEL directly * Remove ctdb_set_current_debuglevel() * Remove the "getdebug" command from ctdb stub in eventscript unit tests * Update relevant eventscript unit tests to use $CTDB_SCRIPT_DEBUGLEVEL Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit 85efa446c7f5c5af1c3a960001aa777775ae562f)

| | | | | | | | | | When using syslog any provided message arguments are ignored and not passed to logger. This means that logger blocks waiting on stdin. That's bad. Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit 50abf597cefe6f8ea2a2ff7694bf84641344a9b1)

* Eventscripts: Change the default reconfigure action to do nothingMartin Schwenke2013-01-071-2/+2
| | | | | | | | | | | | | A default action of restarting the service doesn't obey the principle of least surprise. It cause the NFS service to be implicitly reintroduced.

| | | | | | | | | | | | | | | | 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...
