ctdb is a utility to view and manage a ctdb cluster.
- </p></div><div class="refsect1" lang="en"><a name="id248

8877"></a><h2>OPTIONS</h2><div class="variablelist"><dl><dt><span class="term">-n <node></span></dt><dd><p>
This specifies on which node to execute the command. Default is
to run the command on the deamon running on the local host.
</p></dd><dt><span class="term">-Y</span></dt><dd><p>
You only need to specify this parameter if you run multiple ctdb
daemons on the same physical host and thus can not use the default
name for the domain socket.
- </p></dd></dl></div></div><div class="refsect1" lang="en"><a name="id248

+ </p></dd></dl></div></div><div class="refsect1" lang="en"><a name="id248
8991"></a><h2>Administrative Commands</h2><p>
These are commands used to monitor and administrate a CTDB cluster.
- </p><div class="refsect2" lang="en"><a name="id248
1136"></a><h3>status</h3><p>
+ </p><div class="refsect2" lang="en"><a name="id248
9000"></a><h3>status</h3><p>
This command shows the current status of the ctdb node.
- </p><div class="refsect3" lang="en"><a name="id248
1145"></a><h4>node status</h4><p>
+ </p><div class="refsect3" lang="en"><a name="id248
9009"></a><h4>node status</h4><p>
Node status reflects the current status of the node. There are four possible states:
</p><p>
OK - This node is fully functional.
UNHEALTHY - A service provided by this node is malfunctioning and should be investigated. The CTDB daemon itself is operational and participates in the cluster. Its public IP address has been taken over by a different node and no services are currnetly being hosted. All unhealthy nodes should be investigated and require an administrative action to rectify.
</p><p>
BANNED - This node failed too many recovery attempts and has been banned from participating in the cluster for a period of RecoveryBanPeriod seconds. Any public IP address has been taken over by other nodes. This node does not provide any services. All banned nodes should be investigated and require an administrative action to rectify. This node does not perticipate in the CTDB cluster but can still be communicated with. I.e. ctdb commands can be sent to it.
- </p></div><div class="refsect3" lang="en"><a name="id248
1197"></a><h4>generation</h4><p>
+ </p></div><div class="refsect3" lang="en"><a name="id248
9061"></a><h4>generation</h4><p>
The generation id is a number that indicates the current generation
of a cluster instance. Each time a cluster goes through a
reconfiguration or a recovery its generation id will be changed.
- </p></div><div class="refsect3" lang="en"><a name="id24
81210"></a><h4>VNNMAP</h4><p>
+ </p></div><div class="refsect3" lang="en"><a name="id24
90207"></a><h4>VNNMAP</h4><p>
The list of Virtual Node Numbers. This is a list of all nodes that actively participates in the cluster and that share the workload of hosting the Clustered TDB database records.
Only nodes that are parcipitating in the vnnmap can become lmaster or dmaster for a database record.
- </p></div><div class="refsect3" lang="en"><a name="id24
81224"></a><h4>Recovery mode</h4><p>
+ </p></div><div class="refsect3" lang="en"><a name="id24
90221"></a><h4>Recovery mode</h4><p>
This is the current recovery mode of the cluster. There are two possible modes:
</p><p>
NORMAL - The cluster is fully operational.
</p><p>
RECOVERY - The cluster databases have all been frozen, pausing all services while the cluster awaits a recovery process to complete. A recovery process should finish within seconds. If a cluster is stuck in the RECOVERY state this would indicate a cluster malfunction which needs to be investigated.
- </p></div><div class="refsect3" lang="en"><a name="id24
81248"></a><h4>Recovery master</h4><p>
+ </p></div><div class="refsect3" lang="en"><a name="id24
90244"></a><h4>Recovery master</h4><p>
This is the cluster node that is currently designated as the recovery master. This node is responsible of monitoring the consistency of the cluster and to perform the actual recovery process when reqired.
</p></div><p>
Example: ctdb status
hash:3 lmaster:3
Recovery mode:NORMAL (0)
Recovery master:0
- </pre></div><div class="refsect2" lang="en"><a name="id24
81279"></a><h3>ping</h3><p>
+ </pre></div><div class="refsect2" lang="en"><a name="id24
90275"></a><h3>ping</h3><p>
This command will "ping" all CTDB daemons in the cluster to verify that they are processing commands correctly.
</p><p>
Example: ctdb ping
response from 1 time=0.000144 sec (2 clients)
response from 2 time=0.000105 sec (2 clients)
response from 3 time=0.000114 sec (2 clients)

90302"></a><h3>ip</h3><p>
This command will display the list of public addresses that are provided by the cluster and which physical node is currently serving this ip.
</p><p>
Example: ctdb ip

28545"></a><h3>disable</h3><p>
+ </p></div><div class="refsect2" lang="en"><a name="id25
36595"></a><h3>disable</h3><p>
This command is used to administratively disable a node in the cluster.
A disabled node will still participate in the cluster and host
clustered TDB records but its public ip address has been taken over by
a different node and it no longer hosts any services.
- </p></div><div class="refsect2" lang="en"><a name="id25

36623"></a><h3>ban <bantime|0></h3><p>
Administratively ban a node for bantime seconds. A bantime of 0 means that the node should be permanently banned.
</p><p>
A banned node does not participate in the cluster and does not host any records for the clustered TDB. Its ip address has been taken over by an other node and no services are hosted.
</p><p>
Nodes are automatically banned if they are the cause of too many
cluster recoveries.
- </p></div><div class="refsect2" lang="en"><a name="id25
28598"></a><h3>unban</h3><p>
+ </p></div><div class="refsect2" lang="en"><a name="id25
36646"></a><h3>unban</h3><p>
This command is used to unban a node that has either been
administratively banned using the ban command or has been automatically
banned by the recovery daemon.
- </p></div><div class="refsect2" lang="en"><a name="id25
28610"></a><h3>shutdown</h3><p>

28642"></a><h3>tickle <srcip:port> <dstip:port></h3><p>
+ </p></div><div class="refsect2" lang="en"><a name="id25
36690"></a><h3>tickle <srcip:port> <dstip:port></h3><p>
This command will will send a TCP tickle to the source host for the
specified TCP connection.
A TCP tickle is a TCP ACK packet with an invalid sequence and
TCP connection has been disrupted and that the client will need
to reestablish. This greatly speeds up the time it takes for a client
to detect and reestablish after an IP failover in the ctdb cluster.

28729"></a><h3>getmonmode</h3><p>
+ </p></div><div class="refsect2" lang="en"><a name="id25
36777"></a><h3>getmonmode</h3><p>
This command returns the monutoring mode of a node. The monitoring mode is either ACTIVE or DISABLED. Normally a node will continously monitor that all other nodes that are expected are in fact connected and that they respond to commands.
</p><p>
ACTIVE - This is the normal mode. The node is actively monitoring all other nodes, both that the transport is connected and also that the node responds to commands. If a node becomes unavailable, it will be marked as DISCONNECTED and a recovery is initiated to restore the cluster.
</p><p>
DISABLED - This node is not monitoring that other nodes are available. In this mode a node failure will not be detected and no recovery will be performed. This mode is useful when for debugging purposes one wants to attach GDB to a ctdb process but wants to prevent the rest of the cluster from marking this node as DISCONNECTED and do a recovery.
- </p></div><div class="refsect2" lang="en"><a name="id25
28760"></a><h3>setmonmode <0|1></h3><p>
+ </p></div><div class="refsect2" lang="en"><a name="id25
36808"></a><h3>setmonmode <0|1></h3><p>
This command can be used to explicitely disable/enable monitoring mode on a node. The main purpose is if one wants to attach GDB to a running ctdb daemon but wants to prevent the other nodes from marking it as DISCONNECTED and issuing a recovery. To do this, set monitoring mode to 0 on all nodes before attaching with GDB. Remember to set monitoring mode back to 1 afterwards.
- </p></div><div class="refsect2" lang="en"><a name="id25
28776"></a><h3>attach <dbname></h3><p>
+ </p></div><div class="refsect2" lang="en"><a name="id25
36823"></a><h3>attach <dbname></h3><p>
This is a debugging command. This command will make the CTDB daemon create a new CTDB database and attach to it.
- </p></div><div class="refsect2" lang="en"><a name="id25
28787"></a><h3>dumpmemory</h3><p>
+ </p></div><div class="refsect2" lang="en"><a name="id25
36835"></a><h3>dumpmemory</h3><p>
This is a debugging command. This command will make the ctdb daemon to write a fill memory allocation map to the log file.
- </p></div><div class="refsect2" lang="en"><a name="id25
28798"></a><h3>freeze</h3><p>
+ </p></div><div class="refsect2" lang="en"><a name="id25
36846"></a><h3>freeze</h3><p>
This command will lock all the local TDB databases causing clients
that are accessing these TDBs such as samba3 to block until the
databases are thawed.
This is primarily used by the recovery daemon to stop all samba
daemons from accessing any databases while the database is recovered
and rebuilt.
- </p></div><div class="refsect2" lang="en"><a name="id25
28816"></a><h3>thaw</h3><p>
