硬盘的自动挂载以及添加标签

1、blkid

[root@bogon iso]# blkid /dev/sde2
/dev/sde2: LABEL="YoucaoOSSS" UUID="067d579a-c412-4338-9dde-8bd12840351a" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="409c7031-02"
#blkid可以查看所有的磁盘的id信息
#此外file -s /dev/sde2有相同的效果
[root@bogon iso]# file -s /dev/sde2
/dev/sde2: Linux rev 1.0 ext4 filesystem data, UUID=067d579a-c412-4338-9dde-8bd12840351a, volume name "YoucaoOSSS" (needs journal recovery) (extents) (64bit) (large files) (huge files)

2、lsblk

[root@bogon iso]# lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda           8:0    0    20G  0 disk 
├─sda1        8:1    0     1G  0 part /boot
└─sda2        8:2    0    19G  0 part 
  ├─cl-root 253:0    0    17G  0 lvm  /
  └─cl-swap 253:1    0     2G  0 lvm  [SWAP]
sde           8:64   0 238.5G  0 disk 
├─sde1        8:65   0   8.2G  0 part /data/test/sdb2
└─sde2        8:66   0 230.3G  0 part /data/test/sdb1
sr0          11:0    1  58.2M  0 rom  /run/media/root/VBox_GAs_6.1.16

3、fdisk -l

[root@bogon iso]# fdisk -l
Disk /dev/sde: 238.5 GiB, 256060514304 bytes, 500118192 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x409c7031

Device     Boot    Start       End   Sectors   Size Id Type
/dev/sde1  *           0  17143807  17143808   8.2G 17 Hidden HPFS/NTFS
/dev/sde2       17143808 500118191 482974384 230.3G 83 Linux

4、e2label打标签

e2label /dev/sde2 YoucaoOSSS

5、fstab

• 可以看到是两种挂载方式

[root@bogon iso]# cat /etc/fstab 
/dev/mapper/cl-swap     swap                    swap    defaults        0 0
LABEL="YoucaoOSSS" /data/test/sdb1              ext4    defaults        0 0
[root@bogon iso]# mount -a #立即生效fstab的配置

6、dd

dd if=CentOS-8-based-20201222.iso of=/dev/sde bs=4M
