磁盘的检查：
tune2fs -l /dev/sda5 (对/dev/sda5 进行检查)
理解下面每一行的意思：
machine@machine-virtual-machine:~$ fdisk -l /dev/sd sda sda1 sda2 sda3 sda5 sda6 sda7 sdb sdb1 machine@machine-virtual-machine:~$ tune2fs -l /dev/sda5 tune2fs 1.42.9 (4-Feb-2014) tune2fs: 权限不够 当尝试打开 /dev/sda5 时 找不到有效的文件系统超级块. machine@machine-virtual-machine:~$ sudo tune2fs -l /dev/sda5 [sudo] password for machine: tune2fs 1.42.9 (4-Feb-2014) Filesystem volume name: <none> //卷标 （相当于Windows下的D盘的重命名的名字） Last mounted on: / Filesystem UUID: edd2b532-1560-4804-ab08-509ffee13b50 Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery sparse_super large_file Filesystem flags: signed_directory_hash Default mount options: user_xattr acl Filesystem state: clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 625856 Block count: 2499840 Reserved block count: 124992 Free blocks: 1172007 Free inodes: 429995 First block: 0 Block size: 4096 Fragment size: 4096 Reserved GDT blocks: 610 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 8128 Inode blocks per group: 508 Filesystem created: Wed May 17 20:56:03 2017 Last mount time: Sun May 21 00:12:14 2017 Last write time: Sun May 21 00:12:12 2017 Mount count: 10 Maximum mount count: -1 Last checked: Wed May 17 20:56:03 2017 Check interval: 0 (<none>) Lifetime writes: 13 GB Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 256 Required extra isize: 28 Desired extra isize: 28 Journal inode: 8 First orphan inode: 333696 Default directory hash: half_md4 Directory Hash Seed: 538aa3cd-eb59-4f51-b7b8-a253efa149b8 Journal backup: inode blocks machine@machine-virtual-machine:~$
