This is an alternative to 10.interface and is installed as disabled by default. It should only be used with DisableIPFailover=yes and when IP failover is being handled externally. In this mode CTDB can be informed of public IP address movements using "ctdb moveip". During the "startup" event, this eventscript currently finds any public IP addresses configured in $CTDB_PUBLIC_ADDRESSES and tells CTDB which node they are on using "ctdb moveip". This allows CTDB to send ARPs and tickle-ACKs. Pair-programmed-with: Amitay Isaacs <amitay@gmail.com> Signed-off-by: Martin Schwenke <martin@meltin.net> Reviewed-by: Amitay Isaacs <amitay@gmail.com>
This directory contains run-time support scripts for CTDB.
Selected highlights:
ctdb.init
An initscript for starting ctdbd at boot time.
events.d/
Eventscripts. See events.d/README for more details.
functions
Support functions, sourced by eventscripts and other scripts.
statd-callout
rpc.statd high-availability callout to support lock migration on
failover.
Notes:
* All of these scripts are written in POSIX Bourne shell. Please
avoid bash-isms, including the use of "local" variables (which are
not available in POSIX shell).
* Do not use absolute paths for commands. Unit tests attempt to
replace many commands with stubs and can not do this if commands are
specified with absolute paths. The functions file controls $PATH so
absolute paths should not be required.
