Why does "File system loop detected" crash?

Question

Plesk

find: File system loop detected; `/var/named/chroot/var/named' is part of the same file system loop as `/var/named'.

What is fraught with and how to fix it? If there were no configs in /var/named/chroot/, I would cut off the symlinks, erase them and create files and folders on a new one, but I have little idea about the linux FS and the possible consequences of such waves. I treat these files and folders like command.com in MS-DOS - I'm afraid to touch system files.

Answer 1

doing backup and e2fsck
is generally a strange message, you can’t do hardlinks on directories, and find can recognize symlinks

Answer 2

You have a file system in a loop, in the child directory there is a link to the parent.
So find says it doesn't want to go around in circles.
Look for links in the specified path.
