Solving the difference in space capacity between DF and du viewing is a big problem

Environment: Centos 6.5

Today, there is a strange thing is that df-h when viewing disk space, the display uses a space of 100%, unable to write to the disk, but when viewed with du-sh/home/*, the sum of space used is about 20%.

Finally, it was found that a large file was previously deleted, although it was rm-rf, but because there are other process calls to the file, it is equivalent to not being deleted. When we use RM-RF to delete a file, we simply delete the file's index on disk, not the actual deletion, which is overwritten when a new file is written.

At this point, you can use kill-9 14930来 to end the process and let the disk free up space, such as:

OK, now the capacity of the disk is normal.
