MySQL table is marked as crashed and last (automatic?) repair failed

Question

I was repairing this table suddenly server hanged and when I returned back all tables are ok but this one showing 'in use' and when I try to repair it doesn't proceed.

ERROR 144 - Table './extas_d47727/xzclf_ads' is marked as crashed and last (automatic?) repair failed

What can I do to repair it?

Answer 1

If your MySQL process is running, stop it. On Debian:

sudo service mysql stop

Go to your data folder. On Debian:

cd /var/lib/mysql/$DATABASE_NAME

Try running:

myisamchk -r $TABLE_NAME

If that doesn't work, you can try:

myisamchk -r -v -f $TABLE_NAME

You can start your MySQL server again. On Debian:

sudo service mysql start

Answer 2

Try running the following query:

repair table <table_name>;

I had the same issue and it solved me the problem.

Answer 3

If it gives you permission denial while moving to /var/lib/mysql then use the following solution

$ cd /var/lib/
$ sudo -u mysql myisamchk -r -v -f mysql/<DB_NAME>/<TABLE_NAME>

Answer 4

I needed to add USE_FRM to the repair statement to make it work.

REPAIR TABLE <table_name> USE_FRM;

Answer 5

I got myisamchk: error: myisam_sort_buffer_size is too small as error.

The solution

myisamchk -r -v mysql/<DB_NAME>/<TABLE_NAME> --sort_buffer_size=2G

Answer 6

Go to data_dir and remove the Your_table.TMP file after repairing <Your_table> table.

Answer 7

This is a 100% solution. I tried it myself.

myisamchk -r -v -f --sort_buffer_size=128M --key_buffer_size=128M /var/lib/mysql/databasename/tabloname

Answer 8

I tried the options in the existing answers, mainly the one marked correct which did not work in my scenario. However, what did work was using phpMyAdmin. Select the database and then select the table, from the bottom drop down menu select "Repair table".

• Server type: MySQL
• Server version: 5.7.23 - MySQL Community Server (GPL)
• phpMyAdmin: Version information: 4.7.7
