Troubleshooting Pantheon Issues
Owned by Andrew Mallis
502 errors
Whenever you get a lot of 502s on a pantheon site, run this against the DB.
It shows you the 15 biggest tables i the DB. Usually you can see whats so sad pretty quickly with that
SELECT CONCAT(table_schema, '.', table_name),
CONCAT(ROUND(table_rows / 1000000, 2), 'M') rows,
CONCAT(ROUND(data_length / ( 1024 * 1024 * 1024 ), 2), 'G') DATA,
CONCAT(ROUND(index_length / ( 1024 * 1024 * 1024 ), 2), 'G') idx,
CONCAT(ROUND(( data_length + index_length ) / ( 1024 * 1024 * 1024 ), 2), 'G') total_size,
ROUND(index_length / data_length, 2) idxfrac
FROM information_schema.TABLES
ORDER BY data_length + index_length DESC
LIMIT 15;
Backup and Restore
When the Restore button doesn't work, the Pantheon Support team can also perform this if needed. It can be done manually by...
- Download files from the backup to your local computer.
- Use rsync to upload the Files to your Test environment
- Clone the Test Files over to Live.
It can also be faster to just backup/restore the database if speed is an issue. Again, contact the Support team using the SUPPORT TAB in Pantheon.
