I'm using CentOS6, but I've been researching the capacity of the disk and found a directory with 8MB, even though it's an empty directory.
Is there any file process etc. that existed before as shown on this site ?
[root@XXXXXX 20170501]# ls -al -h 合計 7.9M drwxr-xr-x 2 root root 7.9M 5月 2 00:05 2017 . drwxr-xr-x 98 root root 20K 8月 4 11:05 2017 ..
Perhaps there were many files and directories in that directory before.
If the file system is Ext4, once the number of blocks used in a directory increases, even if the files and directories under it are deleted, the blocks used in that directory will not decrease.
