Description:
Hello,
I'm trying to create a clone of my database running on ndbcluster engine with MySQL Cluster 7.0.7 64 bits.
I can drop my initial database then recreate from a dump but when I want to use my dump to create a clone I have the following error:
ERROR 1005 (HY000) at line 844: Can't create table 'database.table' (errno: 4247)
It seems that UNIQUE KEY are responsible for this error. When I use the dump without UNIQUE KEY it works very good.
Indeed, the whole system crashed several times (in 7.0.5 version) after I've tried this command. So I updated to 7.0.7, now it's only one data node crashed.
The Cluster Orginization:
Cluster Configuration
---------------------
[ndbd(NDB)] 2 node(s)
id=3 @10.0.0.109 (mysql-5.1.35 ndb-7.0.7, Nodegroup: 0, Master)
id=4 @10.0.0.110 (mysql-5.1.35 ndb-7.0.7, Nodegroup: 0)
[ndb_mgmd(MGM)] 2 node(s)
id=1 @10.0.0.105 (mysql-5.1.35 ndb-7.0.7)
id=2 @10.0.0.106 (mysql-5.1.35 ndb-7.0.7)
[mysqld(API)] 2 node(s)
id=5 @10.0.0.107 (mysql-5.1.35 ndb-7.0.7)
id=6 @10.0.0.108 (mysql-5.1.35 ndb-7.0.7)
Here is my configuration:
[ndbd default]
NoOfReplicas=2
DataMemory=200M
IndexMemory=100M
BackupDataDir=/usr/local/mysql/backups
MaxNoOfExecutionThreads=2
MaxNoOfUniqueHashIndexes=20000
MaxNoOfOrderedIndexes=20000
MaxNoOfAttributes=20000
datadir=/usr/local/mysql/data
StringMemory=20
MaxNoOfTables=10000
MaxNoOfTriggers=50000
I think I have the same problem that this issue: http://bugs.mysql.com/bug.php?id=46295
The database is not very big (100 tables) and approximatively 3 UNIQUE KEY per table.
The ouput of one of the data node:
Time: Tuesday 13 October 2009 - 12:22:32
Status: Temporary error, restart node
Message: Assertion (Internal error, programming error or missing error message, please report a bug)
Error: 2301
Error data: ArrayPool<T>::getPtr
Error object: ../../../../../storage/ndb/src/kernel/vm/ArrayPool.hpp line: 422 (block: DBDICT)
Program: ndbmtd

How to repeat:
Use the dump file for at least 2 database with the same config.
Suggested fix:
The first DB can be created without any problem and the second not.
So I think there is a limitation somewhere.
