no more space in database

[leostro]

Hi all,

I have a prestashop instance hosted on OVH.

The plan is cheap and the database is little and after a while the db is full.

I launch that query to finds out heaviest table on mysql:

SELECT 
     table_schema as `Database`, 
     table_name AS `Table`, 
     round(((data_length + index_length) / 1024 / 1024), 2) `Size in MB` 
FROM information_schema.TABLES 
ORDER BY (data_length + index_length) DESC;

here the result of the query

mod140_guest                336.42
mod140_connections          334.47
mod140_connections_source   13.53
mod140_cart                 0.84
...

I do not know so well Prestashop database, I google for that tables on Google but I do not find so much infos...

I would like to delete some data from database to free up space and keep the actual plan

Can someone help me?

You can empty guest, connections and connections_source. They are not very useful statistics databases. I regularly empty them for rows older than a few months.

Thanks @musicmaster

 

I just truncate these tables and it works, no problem on the website and the database is not READONLY anymore!

Thanks for the confirmation, I was a little bit scared of doing a mess.

 

Have a nice day,

Leo

Hi @BenKilr,

 

the same happened to me, I am using OVH and when the database is full they switch them in a readonly state --> the shopping carts stop working 😕

Truncating that table free a lot of spaces and now everything is back to normality.

 

Thanks for the interest
