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. AUTHOR mklost+found has been written by Remy Card <Remy.Card@linux.org>. It is currently being maintained by Theodore Ts'o <firstname.lastname@example.org>. BUGS There are none 🙂 AVAILABILITY mklost+found is part of the e2fsprogs package and is available from http://e2fsprogs.sourceforge.net.
