* ctdb-scripts: Don't use the GNU awk gensub() functionMartin Schwenke2015-01-094-7/+11
| | | | | | | | | | | | | This is a gawk extension and can't be used reliably if just running "awk". It is simple enough to switch to using the standard sub() and gsub() functions. The alternative is to switch to explicitly running "gawk". However, although the eventscripts aren't exactly portable, it is probably better to move closer to portability than further away.

* ctdb-tests: Need to drop public IPs in kill-failover testsMartin Schwenke2014-12-053-3/+49
| | | | | | | | | | | | | | These tests simulate a dead node rather than a CTDB failure, so drop IP addresses when killing a "node" to avoid problems with duplicates. To cope with a CTDB failure a watchdog would be needed to ensure that the public IPs are dropped when CTDB dies. Let's not do that now.

* ctdb-tests: Try to handle IPv6 addresses for local daemonsMartin Schwenke2014-12-051-3/+11
| | | | | | | | | | | | | | | | | | | | | | | If CTDB_USE_IPV6 is set then use IPv6 addresses for nodes and public IPs. This can be useful for some simple tests. However, the node address actually needs to be on lo so that ctdbd can bind to the port on that address, so they actually need to be added as root before running tests, like this: for i in $(seq 1 10) ; do ip addr add "fc00:10::${i}/64" dev lo ; done IPv4 127.0.0.0/8 addresses are somehow magic and only one needs to be on lo so that many can be bound to. Also change the IPv4 node addresses to be (slightly) more exotic. For both IPv4 and IPv6, choose addresses that are compatible with socket wrapper.

* ctdb-scripts: Wait until IPv6 addresses are not "tentative"Martin Schwenke2014-12-051-0/+23
| | | | | | | | | | | | | | | 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.
