Bug #45971 Optimize on NDB table causes full cluster crash (All API/NDB Storage nodes).

Description:
This happens both with. ndbmtd and ndbd. 

mysql -e "optimize table billing_processor_data_dump" avarice

Unfortunatly a data dump is not possible as this table stores customer information.

 

How to repeat:
Run 'OPTIMIZE TABLE [table]'

Hi,

I think I've got the same problem. NDBCluster 7.0.5. Only one table :

CREATE TABLE `foo` (
  `idAutoOT` int(10) unsigned NOT NULL auto_increment,
  `numInt` varchar(20) collate latin1_general_ci NOT NULL,
  `codeBase` varchar(5) collate latin1_general_ci NOT NULL,
  `dateEnvoi` datetime default NULL,
  `blocXML` text collate latin1_general_ci,
  `etat` int(2) unsigned default '0',
  `pjAttendue` int(1) unsigned default '0',
  `dateT` datetime default NULL,
  `agence` varchar(15) collate latin1_general_ci default NULL,
  `codeETL` varchar(20) collate latin1_general_ci default '',
  `codeUI` varchar(3) collate latin1_general_ci default '',
  `otGroupe` int(1) default NULL,
  `pix` int(1) default '0',
  `dateReception` datetime default NULL,
  PRIMARY KEY  (`idAutoOT`),
  KEY `cuOT` (`numInt`,`codeBase`),
  KEY `otcle1` (`dateT`),
  KEY `otcle2` (`dateT`,`etat`),
  KEY `o3` (`codeETL`,`dateEnvoi`),
  KEY `o4` (`codeUI`,`codeETL`)
) ENGINE=MyISAM AUTO_INCREMENT=1179679 DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci
;

There are 100.000 records in this table. When I truncate it and launch an "Optimize table foo' I have no problem, with the records, I get a :

2009-07-20 11:16:02 [MgmSrvr] ALERT    -- Node 3: Forced node shutdown completed. Caused by error 2341: 'Internal program error (failed ndbrequire)(Internal error, programming error or missing error message, please report a bug). Temporary error, restart node'.

And all the nodes of the cluster Crash.

      ndb - bug#45971 - crash during optimize table, make sure free list are searched correctly
                        reuse get_alloc_page (with size + 1) since index might grow
            bug#43683 - optimize table does not return memory,
                        try to move to page with *least* amount of free space

Versions? 6.2+?

no 6.2, optimize not implement in 6.2
6.3.26, 7.0.7 (i.e next version)

weird that triggers didnt do this...

Documented bugfix in the NDB-6.3.26 and 7.0.7 changelogs as follows:

        OPTIMIZE TABLE on an NDB table could in some cases cause SQL and
        data nodes to crash. This issue was observed with both ndbd and
        ndbmtd.
