There are a few potential failure modes when adding an IPv6 address. It takes a little while of duplicate address detection to complete, so wait for a while. After a timeout, also need to check to see if duplicate address detection failed - if it did then actually drop the IP address. This really needs some careful thinking. If CTDB disappears on a node but the node's IP addresses are still on interfaces then the above failure mode could cause the takeover nodes to become banned.

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.
