Got error 121 when reading table
Hello,
Random error on a mysql NDB cluster mysqld node. Mysql Version:5.7.16-ndb-7.5.4
perror gives:
OS error code 121: Remote I/O error
MySQL error code 121: Duplicate key on write or update
The table has no foreign key. The table DDL is similar to:
CREATE TABLE "T" (
"C1" varchar(15) NOT NULL DEFAULT '',
"C2" decimal(8,0) NOT NULL DEFAULT '0',
"C3" decimal(8,0) NOT NULL DEFAULT '0',
"C4" varchar(30) NOT NULL DEFAULT '',
"C5" varchar(5) NOT NULL DEFAULT '',
"C6" date NOT NULL DEFAULT '0000-00-00',
"C7" varchar(5) DEFAULT NULL,
"C8" varchar(5) DEFAULT NULL,
"C9" date DEFAULT NULL,
PRIMARY KEY ("C1","C2","C3","C4","C5","C6")
) ENGINE=ndbcluster DEFAULT CHARSET=latin1
Am I missing something?
