MySQL is one of the most popular database used for web applications. This is because MySQL is an open source database which is highly reliable and cost effective at the same time.
It has two different versions to it actually – the open source version and the Enterprise version. It has all the features you would want from an online database server including cross-platform support, full indexing and high security. And this is the reason user prefers to use MySQL to store their website data.
But relying on a single storage server also means that any issue could lead to your website getting crashed. In the error, we are discussing today in this post all the tables in the database are crashed, and the website goes down. This is the error thrown by MySQL
Table (Table name) is marked as crash and should be repaired
The first step is to obviously identify why it's happening and how much time it would take to restore the table since your website is down and you need to get it up as soon as possible. Well, the time depends on how many tables have crashed. If there is only one table that has crashed and it needs repairing then it would take you only a few minutes but if a large number of tables have crashed, then it would take days to repair the data.
In such a case, it’s always better to use the backup and restore the database to its last correct form. But, if you do not have a backup of your database then you need to move forward with the other solutions mentioned or MySQL database repair tool
Reasons behind the table being marked as crash
There can be several reasons behind this error, including:
- Running out of disk space. This is the most common reason behind this error, so if you are about to upload a large amount of data to your database, you should check the total available disk space before doing that.
- Corruption of data
- Unexpected termination of MySQL
- Power failures
- Hardware issues
- Server crash
- Firmware problems
How to repair your database
MySQL provides its own set of tools which should be your first starting point in case any kind of error occurs. If you do not have the tool, you can either download it or use the subsequent steps below.
This should be the command that needs to be entered in the command line
mysqlcheck -u root -p --auto-repair --check --all-databases
When you run this command, you will be prompted for the password, once you enter it, the command will start running.
If you have shell access, then you can also run the command below from the MySQL console itself
repair table table_name;
You can repair smaller as well as very big tables with this method efficiently
This method is quick, but it is only recommended for tables that are small in size, may be a few MBs but that is it. If they are big tables, you will just end up in a big loop.
To use PHPAdmin, follow the steps below
- Login with your credentials to the PHPAdmin
- Choose the database that needs repair
- Select the tables out of the database
- Now click on the ‘Repair table’ option and you are done
As we mentioned, websites going down can be scary; you can lose a lot of traffic and potential readers. That is why it is highly recommended to always have backups that can be used in situation like these.
