查看当前磁盘情况：/dev/vdb未挂载fdisk -lDisk /dev/vda: 107.4 GB, 107374182400 bytes

1、查看当前的磁盘情况，/dev/vdb未挂载

fdisk -l

Disk /dev/vda: 107.4 GB, 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 Disk label type: dos Disk identifier: 0x000abcf4 Device Boot Start End Blocks Id System /dev/vda1 * 2048 1026047 512000 83 Linux /dev/vda2 1026048 209715166 104344559+ 83 Linux Disk /dev/vdb: 214.7 GB, 214748364800 bytes, 419430400 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

2、格式化vdb

mkfs -t ext4 /dev/vdb

3、挂载磁盘到目录 /cbs（路径需要预先创建）

mount /dev/vdb /cbs

----取消挂载：

umount /dev/vdb

4、设置开机自动挂载

vim /etc/fstab

添加这一条：

/dev/vdb /cbs ext4 defaults 0 0
