Hi folks! We are running several server system with ext4 as file system. An Ubuntu 14.04 server installation has disabled the periodic file system check per default: # uname -r 3.13.0-55-generic # tune2fs -l /dev/sda1 | grep mount Last mounted on: / Default mount options: user_xattr acl Last mount time: Thu Jun 18 11:04:23 2015 Maximum mount count: -1 It seems this change was introduced with Ubuntu 13.10: *https://forums.opensuse.org/showthread.php/437298-fsck-not-needed-ext4-filesystems Therefore my questions: * Is a regular file system check recommended for ext4? (i.e. for consistency) * Is there any detailed documentation what happens while a check is run? Thanks a lot, Georg ��.n��������+%������w��{.n�����{�����ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
