1、添加新磁盘

2、fdisk -l查看磁盘被识别的名称

3、如果输入fdisk -l命令没有找到新的磁盘,需要扫描:

root@kali:~# echo "- - -" > /sys/class/scsi_host/host1/scan
root@kali:~# echo "- - -" > /sys/class/scsi_host/host2/scan
root@kali:~# echo "- - -" > /sys/class/scsi_host/host3/scan

4、创建物理卷

root@kali:~# pvcreate /dev/sdb
  Physical volume "/dev/sdb" successfully created.
root@kali:~# pvs
  PV VG Fmt Attr PSize PFree
  /dev/sda5 kali-vg lvm2 a-- <19.76g 0
  /dev/sdb lvm2 --- 10.00g 10.00g

5、扩展VG卷组

root@kali:~# vgextend kali-vg /dev/sdb
  Volume group "kali-vg" successfully extended
root@kali:~# vgs
  VG      #PV #LV #SN Attr   VSize  VFree
  kali-vg   2   2   0 wz--n- 29.75g <10.00g

6、扩展逻辑卷LVS

root@kali:~# lvextend -L +9G /dev/kali-vg/root
  Size of logical volume kali-vg/root changed from <19.26 GiB (4930 extents) to <28.26 GiB (7234 extents).
  Logical volume kali-vg/root successfully resized.
root@kali:~# lvs
  LV     VG      Attr       LSize   Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert
  root   kali-vg -wi-ao---- <28.26g
  swap_1 kali-vg -wi-ao---- 512.00m
root@kali:~# df -h

/dev/sr0                    56M   56M     0  100% /media/cdrom0

7、同步文件系统

root@kali:~# resize2fs /dev/mapper/kali--vg-root
resize2fs 1.44.3 (10-July-2018)
Filesystem at /dev/mapper/kali--vg-root is mounted on /; on-line resizing required
old_desc_blocks = 3, new_desc_blocks = 4
The filesystem on /dev/mapper/kali--vg-root is now 7407616 (4k) blocks long.

root@kali:~# df -h
