GNU/Linux
From a shell issue the lsblk command, this will list the block devices you can use:
admin@mariadb:~$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
vda 253:0 0 160G 0 disk
└─vda1 253:1 0 160G 0 part /
vdb 253:16 0 9.8T 0 disk
The device /dev/vda is the root disk of your system. It has one partition called /dev/vda1 filling all the space. Then you can see /dev/vdb which is the volume you just attached.
In order to be able to use it you need to format it and mount it somewhere.
This is easily done with:
admin@mariadb:~$ sudo mkfs.ext4 /dev/vdb
Allocating group tables: done
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done
admin@mariadb:~$ sudo mkdir /storage
admin@mariadb:~$ sudo mount /dev/vdb /storage
admin@mariadb:~$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 158G 1.1G 150G 1% /
/dev/vdb 9.7T 38M 9.3T 1% /strorage
You can now store your files on the directory /storage.
对已经使用的目录使用软链接的方式扩容：
cd /home
mv k8s /storage/
ln -s /storage/k8s /home/k8s
这样就建立了一个软连接
cd /home/k8s 实际上进入的是/storage/k8s
