Linux 新增盘符（分区、格盘、挂载、开机自启挂载）

1、查看盘符信息：

[root@dm02 ~]# df -h

[root@dm02 ~]# df -h
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs         63G     0   63G   0% /dev
tmpfs            63G     0   63G   0% /dev/shm
tmpfs            63G   25M   63G   1% /run
tmpfs            63G     0   63G   0% /sys/fs/cgroup
/dev/vda1        99G  3.3G   91G   4% /
tmpfs            63G  4.0K   63G   1% /tmp
tmpfs            13G     0   13G   0% /run/user/0

[root@dm02 ~]# fdisk -l

[root@dm02 ~]# fdisk -l
Disk /dev/vda: 100 GiB, 107374182400 bytes, 209715200 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: 0x07d5d815

Device     Boot Start       End   Sectors  Size Id Type
/dev/vda1  *     2048 209713151 209711104  100G 83 Linux


Disk /dev/vdb: 2 TiB, 2199023255552 bytes, 4294967296 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

发现 Disk /dev/vdb: 2 TiB 新数据库，未分区使用。

2、分区格盘挂载

分区

[root@dm02 ~]# fdisk /dev/vdb

n    p      默认        默认        p        w

--- 重新读取分区表信息

[root@dm02 ~]# partprobe

格盘

[root@dm02 ~]# mkfs -t ext4 /dev/vdb1

挂载

[root@dm02 ~]# mkdir /data
[root@dm02 ~]# mount /dev/vdb1 /data
[root@dm02 ~]# blkid /dev/vdb1
/dev/vdb1: UUID="33abfebc-4872-4f1e-91a5-a1287ceb15a2" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="eaff96a4-01"
[root@dm02 ~]# vim /etc/fstab

UUID=33abfebc-4872-4f1e-91a5-a1287ceb15a2 /data			  ext4    defaults	  1 1
[root@dm02 ~]# mount -all
[root@dm02 ~]# df -h
