Hello,
First of all, thanks for the tools and help you are providing to the community.
I have ran into some problems using the innobackupex/xtrabackup script, although it may just be caused by the InnoDB binaries.
I have the following error:
InnoDB: Error number 75 means ‘Value too large for defined data type’.InnoDB: Some operating system error numbers are described atInnoDB: http://dev.mysql.com/doc/refman/5.1/en/operating-system-error-codes.htmlInnoDB: File name ./my_database/my_big_table.ibdInnoDB: File operation call: ‘stat’.InnoDB: Error: os_file_readdir_next_file() returned -1 inInnoDB: directory ./my_databaseInnoDB: Crash recovery may have failed for some .ibd files!
This error happens when I am running the script in streaming and non-streaming modes. In streaming mode, the data for the table my_big_table.idb is copied but in non-streaming mode, the table data is not copied.
The table size is currently about 5 GB. I am running an amazon AMI 2.6.35.14-95.38.amzn1.i686 and MySQL 5.1.52-1.6.amzn1. This is an EC2 small instance with ext3-formatted persistent storage.
Would you have any idea what could be the cause? Technically I can still use the streaming mode, as it seems to work, but I would like to understand why this is happening, but also, why is the streaming mode working although the error is fired in both cases.
Thanks
Pierre
