mklost+found make a folder to put stray files for recovery.

Some local file systems lack a lost+found directory. This means if the
file system is damaged and needs to be repaired, fsck will not have
anywhere to put stray files for recovery.

You should consider creating a lost+found directory with mklost+found(8).

MKLOST+FOUND(8)                                                                                MKLOST+FOUND(8)

NAME
       mklost+found - create a lost+found directory on a mounted Linux second extended file system

SYNOPSIS
       mklost+found

DESCRIPTION
       mklost+found  is used to create a lost+found directory in the current working directory on a Linux sec‐
       ond extended file system.  There is normally a lost+found directory  in  the  root  directory  of  each
       filesystem.

       mklost+found  pre-allocates disk blocks to the lost+found directory so that when e2fsck(8) is being run
       to recover a filesystem, it does not need to allocate blocks in the filesystem to store a large  number
       of  unlinked  files.   This ensures that e2fsck will not have to allocate data blocks in the filesystem
       during recovery.

OPTIONS
       There are none.
