I’ve just been trying to backup my MythTV tables. Previously I’ve used PHPMyAdmin. However, I thought I would try command line and automate it.
mysqldump -u root -p mythconverg > mythconverg-`date +%F`.sql However, I constantly got a error message
Can't open file: (errno: 145) when using LOCK TABLES mythtv
So i discovered I needed to repair the tables. The above docuimentation is pretty easy but basically.
myisamchk -e *.MYI
Then run the following command on each table that shows errors:
myisamchk -r -q program.MYI
Easy peaasy lemon squeezy!
