MySQL datadir空间问题

Question

I have 450+GB MySQL Database running on linux.

MySQL版本 - 5.6.31

Daily at a certain time I can see a peculiar issue, while I use 'df -h' I can see used space is 650 GB but 'du -h' is showing 450 GB.

Can anyone please help on this?

Answer 1

• df是磁盘可用空间
• du is Disk Used

如果您希望这些匹配，则只有在磁盘使用率为50％时才可能。
