* eventscripts: Remove reconfigure check from samba and winbind eventscriptsMartin Schwenke2013-10-222-4/+0
| | | | | | | | | There is no reconfigure code for these scripts so no need to check for reconfiguration. Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit 41df1637c1d8a7b2f5a9974408db71b1f74cb2f2)
* eventscripts: Remove reconfigure code from httpd eventscriptMartin Schwenke2013-10-221-7/+0
| | | | | | | | | Nothing ever (or has ever) set the "needs reconfigure" flag, so this code is unnecessary. Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit 5b77fd95bda5f1960aca952e1b759231890b56f3)
* eventscripts: Fold ctdb_check_tcp_ports_ctdb() into ctdb_check_tcp_ports()Martin Schwenke2013-10-221-50/+16
| | | | | | | | | A generic framework is no longer needed now that the "ctdb" checker is the only one left. Simplify the code. Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit 044d302b41a2040642355401e3236fcecc3a620a)
* eventscripts: Remove TCP port checks other than the built-in CTDB oneMartin Schwenke2013-10-221-69/+1
| | | | | | | | | | | "ctdb checktcpport" is no longer experimental so the other checkers are no longer required. Remove tests related to the removed checkers. Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit 50e330d0679614bee2e7bab028436e929f74ca50)
* scripts: Remove setting of PATH from functions fileMartin Schwenke2013-10-221-2/+0
| | | | | | | | | | | | | | | | The current setting is inconsistent with settings on most systems, putting /bin before /sbin. Use of /usr/local/bin, which may be required on some systems, is also overridden. This can make it difficult to do interactive debugging of script problems. Rely on the system PATH instead. If system-specific changes need to be made then this can be done in a configuration file.

* scripts: Simplify script_log() to just look at CTDB_SYSLOG variableMartin Schwenke2013-10-221-6/+1
| | | | | | | | | The old logic was actually wrong. If CTDB_LOGFILE is unset then a default is used, not syslog. Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit 79e2029f9bc078126e865aa715100a3870c7604b)
* scripts: Remove support for CTDB_OPTIONS configuration variableMartin Schwenke2013-10-223-18/+8
| | | | | | | | | | | Allowing people to put random options in CTDB_OPTIONS complicates some logic (particularly around use of syslog). If we're going to have variables for options then let's make sure we have a variable for each option and make people use them.

* eventscripts: Become unhealthy faster on nfsd failureMartin Schwenke2013-08-141-3/+2
| | | | | | | | | | | | | | | | | Anecdotal evidence suggests that most nfsd RPC check failures are due to cluster filesystem or storage problem. Apparently these are rarely helped by attempting to restart the NFS service because the restart tends to hang. Fail after 2 nfsd RPC check failures, instead of waiting for 6 failures. Restart on every 10th failure to try to bring the node back to good health. Update unit tests to match.

* eventscripts: New configuration variable $CTDB_RPCINFO_LOCALHOSTMartin Schwenke2013-08-142-1/+8

* eventscripts: Separate out RPC service restart codeMartin Schwenke2013-08-141-41/+56
| | | | | | | | | | | | | | | | | | While doing this: * Explicitly assign RPC program and version information in _nfs_check_rpc_common(). This is more lines of code but is easier to read. * Don't print the options when starting a service. Trying to print it makes the code messy for little benefit. Update the eventscript unit testing code and a Ganesha test to reflect this. Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit e8b531405665885196c95fe1608db33a255bf761)

* eventscripts: When restarting the nfslock service only show output of startMartin Schwenke2013-08-141-2/+2
| | | | | | | | | | | That is, /dev/null the "stop" output. This is consistent with the way CTDB generally deals with the output when stopping a service. It also makes updating the eventscript unit tests easier. Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit c7332526b1b488abefeb4be78a7cd3f2f9abc451)
* scripts: Do not run ctdb tool commands when debugging hung "init" eventMartin Schwenke2013-08-091-2/+6
| | | | | | | | | | | | CTDB daemon is not ready to accept clients in INIT runstate (init event). CTDB daemon will start accepting connections in SETUP runstate (setup event) and later. Also, minor log formatting changes. Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit 81d7ce03b28d592a1337639e14d9ea141e20bfff)
* eventscripts: Use configured RECLOCK file instead of asking CTDBAmitay Isaacs2013-08-091-7/+5
| | | | | | | | | | | On cluster where recovery lock file is not being used, asking CTDB daemon is unnecessary overhead. And if CTDB is using recovery file, then changing configuration without restarting is *stupid*.

* initscript: The wrapper script should export CTDB_SOCKETMartin Schwenke2013-07-291-0/+2
| | | | | | | | | | | | | | This ensures that any invocation of the ctdb tool (within the wrapper) gets the desired value. This at least ensures that ctdbd will be started. If a non-standard value is set for CTDB_SOCKET then command-line users will still need the variable in their environment.

* eventscripts: kill_tcp_connections() should send connections to stdinMartin Schwenke2013-07-291-11/+14
| | | | | | | | | | | | | | | This avoids issuing multiple "ctdb killtcp" commands to terminate tcp connections, one per connection. This will considerably reduce the time when there is a large number of tcp connections. This also makes it possible to avoid calling "ctdb killtcp" when there are no connections. Add a couple of unit tests for killtcp and update eventscript unit test infrastructure to support.

* scripts: Run scriptstatus for hung eventMartin Schwenke2013-07-291-2/+17
| | | | | | | | | | | | | | The timeout information printed by ctdbd is less than useful because it refers to the cumulative time taken by the eventscripts run so far. Adding scriptstatus output indicates where time was actually spent. Since there is now quite a bit of output, serialise the calls to this script using flock. Signed-off-by: Martin Schwenke <martin@meltin.net> Pair-programmed-with: Amitay Isaacs <amitay@gmail.com> (This used to be ctdb commit 1b016b2dfc5d7d3f2a42ce4dfe569608e90eb714)
* eventscripts: A missing interface should cause monitoring to failMartin Schwenke2013-07-191-2/+3
| | | | | | | | | | | | | | | | | | | | | | A missing interface is at least as bad as an interface with a link that is down so should have a similar effect. This couldn't be done previously because orphaned interfaces used to be listed for monitoring. This was worked around in 10.interface in commit 49b2d1bd9554461ed8edbfc21e777c0eca9e1443 and fixed in ctdbd in commit cc1a3ae911d3fee8b87fda5de5ab6d9499d7510a. If $CTDB_PARTIALLY_ONLINE_INTERFACES="yes" then monitoring won't actually fail but the interface is still marked as down. While we're touching this code, use "ip link" instead of "ip addr". It is marginally cheaper but not enough for a separate patch. ;-) This effectively reverts d67955b42f7627be9dae995230c8fcbb8a948ec2.

* eventscripts: Get list of configured interfaces using "ctdb ifaces"Martin Schwenke2013-07-191-3/+3
| | | | | | | | | | This was previosuly changed because ctdbd didn't garbage collect orphaned interfaces. This was fixed in commit cc1a3ae911d3fee8b87fda5de5ab6d9499d7510a. Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit c6ab0f9405d5fa5b0b1693bc92e59da0d555a9d7)

* initscript: Simpify initscript and control CTDB via new ctdbd_wrapperMartin Schwenke2013-07-102-226/+329
| | | | | | | | | | | | | | | Currently the initscript is very complex. This makes it hard to read and hard to add support for new init systems, such as systemd. Create a wrapper called ctdbd_wrapper to be installed alongside ctdbd. This is called by the initscript to start and stop ctdbd. It does the ctdbd option construct and waits until ctdbd is properly initialised before it exits.

* eventscripts: Add new option $CTDB_MONITOR_NFS_THREAD_COUNTMartin Schwenke2013-06-132-0/+38
| | | | | | | | | | | | | | | | | | Consider the following example: 1. There are 256 nfsd threads configured. 2. 200 threads are "stuck" in system calls, perhaps waiting for the underlying filesystem when an attempt is made to restart NFS. 3. 56 threads exit when NFS is stopped. 4. 56 new threads are started when NFS is started. 5. 200 "stuck" threads exit leaving only 56 threads running. Setting this option to "yes" makes the 60.nfs monitor event look for this situation and try to correct it.
