lsblk命令用于以树状的格式显示所有可用的块设备信息：
[[email protected] ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 10G 0 disk ├─sda1 8:1 0 500M 0 part /boot └─sda2 8:2 0 9.5G 0 part ├─rhel-root 253:0 0 8.5G 0 lvm / └─rhel-swap 253:1 0 1G 0 lvm [SWAP] sdb 8:16 0 5G 0 disk ├─sdb1 8:17 0 500M 0 part /lxjtest └─sdb2 8:18 0 200M 0 part [SWAP] sr0 11:0 1 3.8G 0 rom /run/media/root/RHEL-7.2 Server.x86_64
NAME —— 设备的名称
MAJ:MIN —— Linux 操作系统中的每个设备都以一个文件表示，对块（磁盘）设备来说，这里用主次设备编号来描述设备。
RM —— 可移动设备。如果这是一个可移动设备将显示 1，否则显示 0。
TYPE —— 设备的类型
MOUNTPOINT —— 设备挂载的位置
RO —— 对于只读文件系统，这里会显示 1，否则显示 0。
SIZE —— 设备的容量
