MySQL说：＃1194-表'tablename'被标记为已崩溃，应该修复

Question

If tables are crashing it means something is wrong with my system.

MySQL said: 

#1194 - Table 'tablename' is marked as crashed and should be repaired 

My website is currently down because of this.

I know how to repair table from phpmyadmin but is it safe way to repair?

What is the important factor for this issue?

Question. Generally, Why table get crashed?

Answers. These may be the reasons -

1. Server's disk space was full. (Please check disk space in live server)

2. Incorrect shutdown MySQL server/Improperly closing the tables while using the databases.

3. More server load.

Answer 1

First of all - there are many reasons for a crashed table.

• harddisk failure
• sudden server reboot
• server crash
• firmware problems (raid controller or bios)
• defects in the cabling
• etc.

A repair with phpmyadmin does basically the same as the mysqlrepair commandline. I would suggest to repair everything on command line:

mysqlrepair -A --auto-repair
mysqlrepair -A -o

Or start a test:

mysqlrepair -A -c

Answer 2

如果您不需要命令行工具，并且崩溃的原因很可能是MYSQL本身，请从MYSQL运行此命令来修复表：

REPAIR TABLE db_name.table_name;

Answer 3

是的，您可以从phpmyadmin修复表，这不会影响您的数据，还可以使用“ myisamchk”命令从Shell修复表。

Answer 4

Use:

mysqlcheck -u root -p --auto-repair --check --all-databases
(Password prompted)

Enter MySQL password for user root and everything is done.

Answer 5

我从命令行使用它：

mysqlcheck -u root -p --auto-repair --check --optimize --all-databases

Answer 6

Solution :

Just go to database and select table which has problem and select "repair table" option it will fix crash entries in table and solve your problem

Answer 7

If you have ssh access to server you can log in and then execute:

df -h

and you could see something like this:

Filesystem            Size  Used Avail Use% Mounted on
/dev/cciss/xxxx      19G  825M   18G   5% /
/dev/cciss/xxxx     9.4G  4.8G  4.2G  54% /usr
/dev/cciss/xxxx      15G  1.8G   12G  13% /var
/dev/cciss/xxxx      19G   18G    0G   0% /opt
/dev/cciss/xxxx     4.7G  243M  4.3G   6% /tmp
/dev/cciss/xxxx     9.4G  1.5G  7.5G  17% /home

It's LAMP installed on /opt , after having some free disk space, you can run the query (as above was wrote):

Repair table db.mytablecrashed

And you get in the last row:

Table               OP        Msg_type  Msg_text
...
db.mytablecrashed   repair    status    OK
