Situation

An smt-mirror instance had started and was interrupted. In this case the server went down and was brought back up. When attempting to start the smt-mirror again it returned the following errors:

Target: /srv/www/htdocs/repo/$RCE/SLES11-Updates/sle-11-x86_64
D /srv/www/htdocs/repo/$RCE/SLES11-Updates/sle-11-x86_64/.repodata/repomd.xml
DBD::mysql::db selectall_hashref failed: statement contains no result [err was 4 now 2000000000]
Field 'localpath' does not exist (not one of ) at /usr/lib/perl5/vendor_perl/5.10.0/SMT/Mirror/RpmMd.pm line 637.
DBD::mysql::db selectall_hashref failed: statement contains no result [err was 4 now 2000000000]

Resolution

In this case the reason for the errors is that the MySQL table is marked as crashed and needs to be repaired. To determine the issue, and attempt a repair of the table you can follow these steps:

1. mysqlcheck [options] dbname tablename (for example mysqlcheck -uroot -p db smt_stats)

error    : Table './wsu/smt_stats' is marked as crashed and should be repaired

2. /etc/init.d/mysql stop (to stop the mysql service)
3. myisamchk tablename (this will prompt you with the switches needed to fix the errors.)

myisamchk: error: Recordlink that points outside datafile at 10473420
MyISAM-table 'smt_stats.SMT' is corrupted
Fix it using switch "-r" or "-o"

4. mysamchk -r smt_stats.SMT

- recovering (with sort) MyISAM-table 'smt_stats.SMT'
Data records: 139144
- Fixing index 1
Found block that points outside data file at 10473420

5. myisamchk dbname (run again to make sure no more errors are reported)
6. /etc/init.d/mysql start
