mklost+found - create a lost+found directory on a mounted Linux second extended
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.
