6da8126a11 ctdb-eventscripts: New configuration variable CTDB_GANESHA_REC_SUBDIR
Backup and restore of the cluster filesystem can upset the operation

a1e1b81b9c ctdb-tools/ctdb: Detach databases only if all nodes disallow client access
This makes sure that AllowClientDBAttach is set to 0 before detaching any
databases.

If someone enables the tunable between checking of tunable and actual
detaching of databases, then they deserve what they get. :-)

2f2421bae1 ctdb-eventscripts: CTDB_NATGW_PUBLIC_* optional on slave-only nodes
Commit 4ee4925d41 forgot about
CTDB_NATGW_SLAVE_ONLY so it introduces an incorrect failure when this
is set, and CTDB_NATGW_PUBLIC_IFACE or CTDB_NATGW_PUBLIC_IP is unset.

Relax the sanity check to see if CTDB_NATGW_SLAVE_ONLY is set.

Update the documentation to explicitly state that
CTDB_NATGW_PUBLIC_IFACE and CTDB_NATGW_PUBLIC_IP are optional and
unused if CTDB_NATGW_SLAVE_ONLY is set.  It would be possible to
insist that CTDB_NATGW_PUBLIC_IFACE and CTDB_NATGW_PUBLIC_IFACE should
be unset in that case.  However, it is more reasonable to allow
consistent configuration across nodes except with some nodes
configured slave-only.

Add tests, update infrastructure and fix a thinko in the stub's
"natgwlist" implementation.

2532149f8f ctdb-scripts: Enhancements to hung script debugging
* Add stack dumps for "interesting" processes that sometimes get
  stuck, so try to print stack traces for them if they appear in the
  pstree output.

* Add new configuration variables CTDB_DEBUG_HUNG_SCRIPT_LOGFILE and
  CTDB_DEBUG_HUNG_SCRIPT_STACKPAT.  These are primarily for testing
  but the latter may be useful for live debugging.

* Load CTDB configuration so that above configuration variables can be
  set/changed without restarting ctdbd.

b5ebff6931 tools/ctdb: "ctdb runstate" now accepts optional expected run state arguments
If one or more run states are specified then "ctdb runstate" succeeds
only if ctdbd is in one of those run states.

At the moment, if the "setup" event fails then the initscript succeeds
but ctdbd exits almost immediately.  This behaviour isn't very
friendly.

The initscript now waits until ctdbd is in "startup" or "running" run
state via the use of "ctdb runstate startup running", meaning that ctdbd
has successfully passed the "setup" event.

The "setup" event code in 00.ctdb now waits until ctdbd is in the
"setup" run state before proceeding via the use of "ctdb runstate setup".

0445c988e2 recoverd: Fix tunable NoIPTakeoverOnDisabled, rename to NoIPHostOnAllDisabled
This really needs to be per-node.  The rename is because nodes with
this tunable switched on should drop IPs if they become unhealthy (or
disabled in some other way).

* Add new flag NODE_FLAGS_NOIPHOST, only used in recovery daemon.

* Enhance set_ipflags_internal() and set_ipflags() to setup
  NODE_FLAGS_NOIPHOST depending on setting of NoIPHostOnAllDisabled
  and/or whether nodes are disabled/inactive.

* Replace can_node_servce_ip() with functions can_node_host_ip() and
  can_node_takeover_ip().  These functions are the only ones that need
  to look at NODE_FLAGS_NOIPTAKEOVER and NODE_FLAGS_NOIPHOST.  They
  can make the decision without looking at any other flags due to
  previous setup.

* Remove explicit flag checking in IP allocation functions (including
  unassign_unsuitable_ips()) and just call can_node_host_ip() and
  can_node_takeover_ip() as appropriate.

* Update test code to handle CTDB_SET_NoIPHostOnAllDisabled.

not be invoked with Samba version 4.x which correctly specifies the
priority for each database.
