* event scripts: add logging for low memory conditionsRusty Russell2010-02-091-0/+10
| | | | | | | | We should never enter swap; if we do, show the memory state of the machine and the process list. This will help us diagnose what caused the condition before it's too late and the box starts OOM-killing processes.

* initscript: handle spaces in option values inserted into $CTDB_OPTIONS.Martin Schwenke2010-01-221-7/+8
| | | | | | | | | | | | | | | | | | | This puts single quotes around everything and uses eval on the command-lines that actually start ctdbd. The eval causes the single quotes to be interpreted. The "redhat" init style no longer uses the Red Hat daemon function. It loses the quoting and re-splits on spaces. Instead we add an extra line that uses the success/failure functions to keep things pretty. Note that this means that we don't respect daemon's $DAEMON_COREFILE_LIMIT variable but we do our own core file handling with $CTDB_SUPPRESS_COREFILE anyway. daemon's core file handling was probably overriding what we were doing anyway, so this can be regarded as a bug fix.

* | config: load 'ctdb' config before 'nfs' config in statd-calloutStefan Metzmacher2009-12-161-0/+1
|/ | | | | | | | | | | | | All other scripts do 'loadconfig ctdb' before any other 'loadconfig foo' call. I think we should do the same in statd-callout. Otherwise it's very confusing, if you have configured some Options in /etc/sysconfig/ctdb, but /etc/ctdb/statd-callout doesn't notice them. metze (This used to be ctdb commit 10d95581fb90bfdf58ec32345c4e36c27acf4f37)
* Bond devices can have any name the user configures, soRonnie Sahlberg2009-12-091-8/+13
| | | | | | | | | | | | | when checking link status for an interface, first check if this interface is in fact a bond device (by the precense of a /proc/net/bonding/IFACE file) and use that file for checking status. Othervise assume ib* is an infiniband interface which we donnt know how to check, or otherwise it is an ethernet interface and ethtool should hopefully work.

* Eventscript argument cleanups and introduction of ctdb_standard_event_handler.Martin Schwenke2009-12-0117-81/+101
| | | | | | | | | | | | | | | | | | | The functions file no longer causes a side-effect by doing a shift. It also doesn't set a convenience variable for $1. All eventscripts now explicitly use "$1" in their case statement, as does the initscript. The absence of a shift means that the takeip/releaseip events now explicitly reference $2-$4 rather than $1-$3. New function ctdb_standard_event_handler handles the status and setstatus events, and exits for either of those events. It is called via a default case in each eventscript, replacing an explicit status case where applicable.
