Data node won't start (no replies)

Hello!

I'm trying to configure a MySQL Cluster on 4 machines, all runing Debian.

MySQL Cluster Environment:

MGM - 192.168.1.10
NDB1 - 192.168.1.30
NDB2 - 192.168.1.40
MYSQLD - 192.168.1.20

I installed all from the Binary Relases for Generic-Linux

1. I started the MGM node: ndb-mgmd -f /var/lib/mysql-cluster/config.ini
The config.ini file:

[ndbd default]

NoOfReplicas=2
DataMemory=80M
IndexMemory=18M

[tcp default]

portnumber=2202

[ndb_mgmd]

id = 1
hostname = 192.168.1.10
datadir=/var/lib/mysql-cluster

[ndbd]

id = 3
hostname = 192.168.1.30
datadir = /usr/local/mysql/data

[ndbd]

id = 4
hostname = 192.168.1.40
datadir = /usr/local/mysql/data

[mysqld]

id = 2
hostname=192.168.1.20

2. Now I start the data nodes with: ndbd
And wait until the node start

3. Check on MGM node with: ndb_mgm

ndb_mbm> show
Connected to Management Server at: localhost:1186
Cluster Configuration
---------------------
[ndbd(NDB)] 2 nodes
id=3 @192.168.1.30 (mysql-5.6.23 ndb-7.4.5, Nodegroup: 0, *)
id=4 (not connected, accepting connect from 192.168.1.40)

[ndb_mgmd(MGM)] 1 node(s)
id=1 @192.168.1.10 (mysql-5.6.23 ndb-7.4.5)

[mysqld(API)] 1 node(s)
id=5 (not connected, accepting connect from 192.168.1.20)

4. And I try to start MySQL server on the Data Node already started (id=3)

shell> /etc/init.d/mysql start
Starting MySQL ....(...) The server quit without updating PID file (/usr/local/mysql/data/NDB1.pid)
[FAIL...failed!

The my.cnf file has:

[mysqld]

ndbcluster
ndb-connectstring = 192.168.1.10

[mysql_cluster]

ndb-connectstring = 192.168.1.10



The MySQL server is installed correctly because if do a default my.cnf file (without the cluster lines) the server starts.
It happens the same with the other data node.

What should I do? Is there something wrong? I have searched a lot in the Inernet and in your forums but I couldn't find the solution

Thanks you very much,

Cristian

PK Auto increment (no replies)

I am being told that because our DB is clustered every InnoDB table needs to have a Primary Key that is an auto_increment value.

Is that true, or am I possibly only getting partial information from the individual administering our DB?

zero values in ndb_binlog_index (no replies)

Hello. I try to set up replication between two clusters.
If I understand correctly, according to this config, mysql must write events in ndb_binlog_index even without working slave:

server-id=3
log-bin-trust-function-creators = 1
log-bin=log-bin.log
binlog-format=ROW
ndb-log-transaction-id=1
ndb-log-update-as-write=0
ndb-log-apply-status=1
replicate-wild-do-table=my_test.replication%
replicate-wild-do-table=mysql.ndb_apply_status
replicate-wild-do-table=mysql.ndb_replication

So, it writes, but in very strange way:

mysql-office> select file,orig_server_id,orig_epoch,position,next_position from mysql.ndb_binlog_index;
+------------------+----------------+------------+----------+---------------+
| file | orig_server_id | orig_epoch | position | next_position |
+------------------+----------------+------------+----------+---------------+
| ./log-bin.000001 | 0 | 0 | 217 | 596 |
+------------------+----------------+------------+----------+---------------+
1 row in set (0,00 sec)

mysql-office> show binlog events;
+----------------+-----+-------------+-----------+-------------+-------------------------------------------------------------+
| Log_name | Pos | Event_type | Server_id | End_log_pos | Info |
+----------------+-----+-------------+-----------+-------------+-------------------------------------------------------------+
| log-bin.000001 | 4 | Format_desc | 3 | 120 | Server ver: 5.6.23-ndb-7.4.5-cluster-gpl-log, Binlog ver: 4 |
| log-bin.000001 | 120 | Query | 3 | 217 | use `my_test`; truncate table replication |
| log-bin.000001 | 217 | Query | 3 | 285 | BEGIN |
| log-bin.000001 | 285 | Table_map | 3 | 343 | table_id: 79 (my_test.replication) |
| log-bin.000001 | 343 | Table_map | 3 | 409 | table_id: 71 (mysql.ndb_apply_status) |
| log-bin.000001 | 409 | Write_rows | 3 | 474 | table_id: 71 |
| log-bin.000001 | 474 | Write_rows | 3 | 527 | table_id: 79 flags: STMT_END_F |
| log-bin.000001 | 527 | Query | 3 | 596 | COMMIT |
+----------------+-----+-------------+-----------+-------------+-------------------------------------------------------------+
8 rows in set (0,00 sec)

There are simple situation (no working slave), but when replication is and working, all fine (data changes in both clusters, there is some non zero values in ndb_apply_status) except ndb_binlog_index.

Is it bug or my fault in configuration?

I built the API examples
when I run:

Cluster management server was not ready within 30 secs.

What is the correct connection syntax?

ndbmtd unexpected high memory usage (1 reply)

Hello,
I am experiencing higher system memory usage than expected when using ndbmtd instead of ndbd. By my count from config.ini each node should be using around 13GB of memory, but looking at the ndbmtd parent process it has consumed around 36GB instead. I know that the RedoBuffer is a "per LDM" value and that each LDM thread is using the value from RedoBuffer. Are there other values that this is true for? It's consuming more than twice what I expect. I've used ndb_config to make sure that the "actual live" values match config.ini values. Perhaps it has something to do with my ThreadConfig and extra threads consuming memory? Any insight is welcome.

Hi all,

Here I set up a little and study the system of MySQL Cluster for some months.

In some time I have to make a small presentation of what I'm there for two months, but I have a little problem: I have a memory hole.

Indeed, I do not remember, once the complete cluster is started me what's going on if you count the Manager (ndb_mgmd)? The system is always 100% functional? Or nothing works?

So that was just a stupid question ..

Thank you in advance,

Florian.

Hello all,

When creating MySQL cluster using Auto-installer on Hyper-v , and trying to add the local machine as a host, it fail to get the resource information of the machine giving me [error : Number_of_Processors] , also, doesn't give the right MySQL install directory , and MySQL data directory.

Is this related to creating cluster using hyper-V?

At this Point, all Looks fine.

Now i got problems starting my application nodes (mysqld).
Even the process is running, the state via ndb_mgm does not Change.
It seems, the application node never speaks to the Management nodes, even it is on the same System.

Annoying: why does node 3 (application node 1) allocates ip 9.251.82.79?
all other machines are located at the 10.x.x.x subnet.

May this cause some Trouble? I tried binding the Adapter to the 10.x.x.x-address of the machine - successfully, but it does not connect to the cluster anyway.

And what does this log entry mean:

2015-06-03 13:17:41 2324 [Warning] NDB: server id set to zero - changes logged to bin log with server id zero will be logged with another server id by slave mysqlds




All machines are in the same vlan, all Firewalls are turned off and my user is owning the Domain admin role.

Realy Need some Input solving that... .

I'm trying to use the resources table to see if buffers are allocated correctly.
I haven't been able to find good documentation on what config parameters would apply to the numbers i'm looking at.
In the data shown below it seems i should have larger numbers for RESERVED and FILE_BUFFERS, JOBBUFFERS and TRANSPORTER_BUFFERS. I'm not using disk-based tables so DISK_PAGE_BUFFER should not matter.

Can someone recommend the config parameters i should be looking at?

Hi everyone, I 'm totally new to mysql cluster, recently I encountered a strange question, when I tried to create an new table for a database, the error message shown: "ERROR 1114 (HY000): The table 'xxx' is full". Only if I dropped another table first, it would be success. I have 229 tables totally in the system(all schemata). And I noticed the "max_data_size" and "data_free" for certain database are 0M, but it still be able to be inserted, and "data_size" is larger then 0M, I would like to know why?

Thanks

Jeff

Is it possible to enable mysql cluster to directly show connecting-client's error detail info in logs but not just an "unknow error code"? (no replies)

Dear MySQL cluster pioneers,

I just installed mysql-cluster-gpl-7.4.6-linux-glibc2.5-x86_64.tar in Linux servers and windows 2008 server, but is it possible to enable mysql cluster to directly show connecting-client's error detail info in logs but not just an "illegal error code 240"? I mean the detail errors for cluster's connection clients but not only for the cluster's system itself.

Even I use cluster's mgm cosole to enable clusterlog's debug info, or even I add LogLevelError, LogLevelInfo and LogDestination(all output) in config.ini file, or even I use perror command, I cann't get any detail error info to get an effective solution clues.

I have turn on the detail log of every client's every executing query, but how to enable showing cluster's returning detail info for every query?

How to make procedure store in NDBCluster as tables? (no replies)

hi, everyone,

It seems that I have found the Error code 1296 with 240 error's reason: the mysql cluster doesn't make
DB's procedure shareed by multi SQL node and multi users.

And I have check mysql's offical document on "create procedure" statement syntax, it seems there is no storageengine syntax to make procedure public-shared as tables.

So how to make procedure store in NDBCluster as tables stored in NDBengine?

Is the only way to share a procedure by just making mysql-cluster's users accounts sharered by multi SQL nodes?

Bye.

Cannot add unique constraint with fk column (3 replies)

Hi,

I try to get NDB working with OpenStack and found the following code not working:

==========

CREATE TABLE networks (
tenant_id VARCHAR(255),
id VARCHAR(36) NOT NULL,
name VARCHAR(255),
status VARCHAR(16),
admin_state_up BOOL,
shared BOOL,
PRIMARY KEY (id)
);


CREATE TABLE ports (
tenant_id VARCHAR(255),
id VARCHAR(36) NOT NULL,
name VARCHAR(255),
network_id VARCHAR(36) NOT NULL,
mac_address VARCHAR(32) NOT NULL,
admin_state_up BOOL NOT NULL,
status VARCHAR(16) NOT NULL,
device_id VARCHAR(255) NOT NULL,
device_owner VARCHAR(255) NOT NULL,
PRIMARY KEY (id),
FOREIGN KEY(network_id) REFERENCES networks (id)
);


ALTER TABLE ports ADD CONSTRAINT uniq_ports0network_id0mac_address UNIQUE (network_id, mac_address);

============

This gives me ERROR 1296 (HY000): Got error 4243 'Index not found' from NDBCLUSTER

I have played a bit with the code and if I add KEY (network_id) for 'ports' creation everything works. Just puzzled whether this is a bug or a specified behavior.. If the latter is true I will have to convince OpenStack developers to add necessary key.

Thanks!

No error

2. ./bin/ndb_mgm -e "start bakcup 201505"
No error

3. When the backup is executed with crontab. There is the error message.
---------------------------------------------------------------------------
[MgmtSrvr] ALERT -- Node 3: Backup request from 2 failed to start. Error: 1302
---------------------------------------------------------------------------

Is there any bug for mysql cluster "Start Backup" with Crontab?


Please help me.

Thanks
