Yesterday one of our computer’s user partition filled up automatically that caused database corruption in the mysql database. After freeing the space from the partition, we ran some commands to repair and recover mysql database. Here is the list what we did yesterday:

1.cd into your directory where your database files are stored. In my case it was in the /usr…/data/mysql/ folder.

2.Then We run this command:
myisamchk *.MYI | grep -3 –color corrupted

3.After running above command this should give you some output on the current state of your database files & indicate which file is corrupted and need to repair. This also gives you the next command to run on the line that is:
Fix it using switch “-r” or “-o”

4.So that is we did
myisamchk -r file.MYI

5.Your database should be repaired

MythTV is a home entertainment application, which is freely available as a open source solution for live streaming programs, and converts into a computer with the necessary supporting hardware components. This application is able to run on different operating systems such as Linux, Macintosh, FreeBSD, etc and primarily uses MySQL database as the backend to store the recordings. Having started in 2002, this application has undergone several developments and now is a competent combination of a TV and a computer. Having said that, at times you may face some issues while operating on the MythTV. Sometimes these issues may be because of corrupt database that can appear because of several reasons including virus infections, abrupt or unplanned system shutdowns, etc. You should try to fix such issues by using in-built MySQL methods failing which the use of a third-party MySQL repair software to repair MySQL database is a must.
