* Event scripts: Respect CTDB_MANAGES_NFS and add function log_status_cat.Martin Schwenke2009-11-251-0/+6
| | | | | | Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit 5d97c07be13a8209a81dfc8f73e49371949e4dc3)
* More eventscript cleanups. Initial smoke testing seems OK.Martin Schwenke2009-11-251-123/+43
| | | | | | | | | | Apart from lots of cleanup work, this also fixes a bug where the share checks didn't used to cope with directory names containing spaces. The previous commit also loaded the config incorrectly. Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit 3c93336ab92c2e4829ff4dc360045bfa6df21d50)

* Eventscripts: Untested factorisations and introduction of status event.Martin Schwenke2009-11-131-38/+162
| | | | | | | | | | | | | This is the first stage of an experimental change to eventscripts. Ronnie and I did a few hours of factorisation of 40.vsftpd and applied many of the changes to 41.httpd. Other eventscripts were also modified. At this stage this is completely untested.

* Clean up ctdb_check_directories* eventscript functions.Martin Schwenke2009-10-121-10/+11
| | | | | | | | | | | | | | | | | | | | | | | | There are 2 problems with this code: * The loop in ctdb_check_directories_probe() breaks on filenames containing whitespace. The fix to protect them is to pass "$@" to this function and have it operate on "$@". Note that there's still a problem with whitespace in filenames in the 50.samba eventscript. To fix this ctdb_check_directories_probe should read the filenames from stdin. Another time... * The check for '%' in filenames in ctdb_check_directories_probe() ends up involving several forks. On a modern machine this can cost a couple of minutes when checking a large number of directories. The fix is to use a case statement.

* 40.vsftpd monitor event only fails after 2 failures to connect to port 21.Martin Schwenke2009-09-301-0/+34
| | | | | | | | | | | | | | | | | | | | Change the monitor event in 40.vsftpd so it only fails if there are 2 successive failures connecting to port 21. This reduces the likelihood of unhealthy nodes due to vsftpd being restarted for reconfiguration due to node failover or system reconfiguration. New eventscript functions ctdb_counter_init, ctdb_counter_incr, ctdb_counter_limit. These are used to count arbitrary things in eventscripts, depending on the eventscript name and a tag that is passed, and determine if a specified limit has been hit. They're good for counting failures! These functions are used in 40.vsftpd and also in 01.reclock - the latter used to do the counting without these functions.

| | | | | | | | | | | | | This fixes tcp port monitor events on systems, where netcat or nc is not found in /usr/bin/, Debian, for instance. The patch also separates the process of finding the binaries and calling them, moving the detection outside of the loop over the ports list.

| | | | | | | | | | Kevin Collins noticed that RHEL5 grep-2.5.1-54.2.el5 built for x86 does not handle \s while the exact same RHEL5 package for amd64 does! [[:space:]] is more portable.
