Verify that CIFS connections are monitored and that CIFS tickles are sent.
|
|
|
|
We create a connection to the CIFS server on a node and confirm that
|
|
this connection is registered by CTDB. Then disable the relevant CIFS
|
|
server node and ensure that it send an appropriate reset packet.
|
|
|
|
Prerequisites:
|
|
|
|
* An active CTDB cluster with at least 2 nodes with public addresses.
|
|
|
|
* Test must be run on a real or virtual cluster rather than against
|
|
local daemons.
|
|
|
|
* Test must not be run from a cluster node.
|
|
|
|
* Clustered Samba must be listening on TCP port 445.
|
|
|
|
Steps:
|
|
|
|
1. Verify that the cluster is healthy.
|
|
2. Connect from the current host (test client) to TCP port 445 using
|
|
the public address of a cluster node.
|
|
3. Determine the source socket used for the connection.
|
|
4. Using the "ctdb gettickle" command, ensure that CTDB records the
|
|
connection details.
|
|
5. Disable the node that the connection has been made to.
|
|
6. Verify that a TCP tickle (a reset packet) is sent to the test client.
|
|
|
|
Expected results:
|
|
|
|
* CTDB should correctly record the connection and should send a reset
|
|
packet when the node is disabled.
