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 the takeover node sends 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.
|
|
|
|
Expected results:
|
|
|
|
* CTDB should correctly record the connection and the takeover node
|
|
should send a reset packet.
