and a ctdb command to pull the talloc memory map from a recovery daemon
ctdb rddumpmemory
(This used to be ctdb commit d23950be7406cf288f48b660c0f57a9b8d7bdd05)
The controls only modify the runtime setting of which public addresses a node
can server and does not modify /etc/ctdb/public_addresses.
To make the change permanent you also need to edit /etc/ctdb/public_addresses
manually.
After ip addresses have been added/deleted you need to invoke a recovery
for the ip addresses to be redistributed.
(This used to be ctdb commit f8294d103fdd8a720d0b0c337d3973c7fdf76b5c)
Add back the controls to enable/disable monitoring we used to have for debugging but removed a while ago
(This used to be ctdb commit 8477f6a079e2beb8c09c19702733c4e17f5032fe)
Vacumming used to delete one record at a time on all nodes, that was
m*n behaviour and would require a huge storm of ctdb->ctdb controls and just wouldnt scale at all.
The new vacuming process collects all records to be deleted locally and then only sends 1 control to the other nodes. This control contains a list of all records to be deleted.
(This used to be ctdb commit 9e625ece19a91f362c9539fa73b6b2108f0d9c53)
ctdb moveip <IPADDRESS> <NODE>
which can be used to manually fail an ip address over to a specific node.
This can only be used if DeteministicIPs are disabled and also only if NoIPFailback is enabled.
(This used to be ctdb commit ffee062b7e26a6aa6ad254edb58399040ecaa542)
add a new control that causes the node to drop the current nodes list
and reread it from the nodes file.
During this operation, the node will also drop the tcp layer and restart it.
When we drop the tcp layer, by talloc_free()ing the ctcp structure
add a destructor to ctcp so that we also can clean up and remove the references in the ctdb structure to the transport layer
add two new commands for the ctdb tool.
one to list all nodes in the nodesfile and the second a command to trigger a node to drop the transport and reinitialize it with the nde nodes file

memory tree to stdout. This is much more useful than putting it in the log, and also fixes
a bug where the pipe would overflow internally and cause ctdbd to lockup
(This used to be ctdb commit e236979e2162d9bd7a495086342168a696cf76c5)
ctdb vacuum : vacuums all the databases, deleting any zero length
ctdb records
ctdb repack : repacks all the databases, resulting in a perfectly
packed database with no freelist entries
(This used to be ctdb commit 3532119c84ab3247051ed6ba21ba3243ae2f6bf4)
ctdb_recoverd.c
Always handle banning/unbanning locally on the node that is being
banned/unbanned instead of on the recovery master.
This means that if a ban request comes in to the recovery master for a
remote node, we pass the request on to the remote node instead of
setting up the ban and ban timeouts locally.
ctdb.c
send ban/unban requests to the node being banned/unbanned instead of to
the recmaster
(This used to be ctdb commit 880dd9f5fd0b91e450da93e195cc5c62cb1dcd6e)
monitoring should always be enabled
(though a node may want to temporarily disable running the "monitor"
event scripts but can do so internally without the need for this
control)
(This used to be ctdb commit e3a33618026823e6af845fd8513cddb08e6b5584)
the recmaster or not.
return 0 if the node is the recmaster and 1 (true) if it is not or if
we could not communicate with the ctdb daemon.
call it 'isnotrecmaster' to cope with that if the tool could not bind to
the socket to tyalk to the daemon, the tool will automatically return an
error and exit code 1
thus the tool will only return 0 if it could talk successfully to the
local daemon and if the local daemon confirms this node is the recmaster
(This used to be ctdb commit ae5fcb790b6c3985f514fa8a96bc00c2619f2a28)
and merge into a big list since with the deassociation between a node
and a public ipaddress the /etc/ctdb/public_addresses files can
differ between nodes and no node know about all public addresses that a
cluster can use
(This used to be ctdb commit e208294fed183977cacc44b2cd1195c11d967c18)
this command no longer makes sense when there is no on-to-one mapping
between a node and its default public ip
