1.在虚拟机关闭的状态下选中需要扩容的虚拟机-设置-硬件- 硬盘-扩展-填写扩大到的值。 2.打开虚拟机 对新增的硬盘空间做新增分区硬盘数没有增加增加的是空间

# pvcreate /dev/sda3
WARNING: xfs signature detected on /dev/sda3 at offset 0. Wipe it? [y/n]: yWiping xfs signature on /dev/sda3.Physical volume /dev/sda3 successfully created.

6. PV加入VGvgextend后接VG Name我的系统中为cl_server8
# vgdisplay--- Volume group ---VG Name clSystem ID Format lvm2Metadata Areas 1Metadata Sequence No 3VG Access read/writeVG Status resizableMAX LV 0Cur LV 2Open LV 2Max PV 0Cur PV 1Act PV 1VG Size 9.00 GiBPE Size 4.00 MiBTotal PE 2303Alloc PE / Size 2303 / 9.00 GiBFree PE / Size 0 / 0 VG UUID dYdb4l-wMUh-e2xv-WiaJ-Oa52-NvdF-s5ICJC# vgextend cl /dev/sda3
7. VG加入LV
# lvextend -l 6416 /dev/cl_server8/root
Size of logical volume cl/root changed from 14.00 GiB (2047 extents) to 17.99 GiB (4606 extents). Logical volume cl/root successfully resized.
6416 ”和“/dev/cl_server8/root”来源详解 “6416 ”来自于vgdisplay命令的Free PE/Size字段:
# vgdisplay--- Volume group ---VG Name cl...VG Size 25.99 GiBPE Size 4.00 MiBTotal PE 4862Alloc PE / Size 2303 / 9.00 GiBFree PE / Size 6416 / 14.00 GiBVG UUID dYdb4l-wMUh-e2xv-WiaJ-Oa52-NvdF-s5ICJC
“/dev/cl_server8/root”来自于lvdisplay命令的LV Path字段。
# lvdisplay--- Logical volume ---LV Path /dev/cl_server8/rootLV Name rootVG Name cl_server8LV UUID 1Y1Lm8-nEvY-pqyA-y4C4-eIZ5-Ix38-OgAUNSLV Write Access read/writeLV Creation host, time server8, 2021-05-07 20:16:24 0800LV Status available# open 2LV Size 4.00 GiBCurrent LE 1024Segments 1Allocation inheritRead ahead sectors auto- currently set to 8192Block device 253:18. 调整文件系统大小本例中是xfs文件系统使用xfs_growfs命令调整若其他文件系统如ext4使用resize2fs命令注意区分。
