* ctdb-eventscripts: New configuration variable CTDB_GANESHA_REC_SUBDIRMartin Schwenke2014-06-111-0/+15
| | | | | | | | | | | | | | Backup and restore of the cluster filesystem can upset the operation of 60.ganesha by changing the contents of this subdirectory. Allow this subdirectory to be configured to a subdirectory that is ignored by backup and restore processes.

* ctdb-tools/ctdb: Detach databases only if all nodes disallow client accessAmitay Isaacs2014-04-231-0/+4
| | | | | | | | | | | 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. :-) Signed-off-by: Amitay Isaacs <amitay@gmail.com> Reviewed-by: Michael Adam <obnox@samba.org>
* ctdb-eventscripts: CTDB_NATGW_PUBLIC_* optional on slave-only nodesMartin Schwenke2014-04-141-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | Commit 4ee4925d416a86341bd76c11fa99ec9173682a1d 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.

| | | | | | | | | | | | | | This adds more serialisation to the startup, ensuring that the "startup" event runs after everything to do with the first recovery (including the "recovered" event).

| | | | | | | | | | | | | | | | | | | | | 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".

* recoverd: Fix tunable NoIPTakeoverOnDisabled, rename to NoIPHostOnAllDisabledMartin Schwenke2013-05-071-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | Samba versions 3.6.x and older do not set the database priority. This can cause deadlock between Samba and CTDB since the locking order of database will be different.
