NAME         top

       mklost+found  - create a lost+found directory on a mounted Linux sec‐
       ond extended file system

SYNOPSIS         top


DESCRIPTION         top

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

       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.
