但我不确定如何调整LV的大小而不会丢失数据.

如何调整逻辑卷的大小？
要扩展到所有可用空间：
lvresize -rl +100%FREE /dev/vg_proxy/lv_root
或者,增长到绝对/相对值：
lvresize -rL 30G /dev/vg_proxy/lv_root lvresize -rL +5G /dev/vg_proxy/lv_root
意思有些不同.但是,这就是我通常使用这两个选项的方式.您可以在手册页中阅读更多内容.
-l,–extents [+|-]LogicalExtentsNumber[%{VG|LV|PVS|FREE|ORIGIN}]
Change or set the logical volume size in units of logical extents. With the + or – sign the value is added to or subtracted from the actual size of the logical volume and without it,the value is taken as an absolute one. The number can also be expressed as a percentage of the total space in the Volume Group with the suffix %VG,relative to the existing size of the Logical Volume with the suffix %LV,as a percentage of the remaining free space of the PhysicalVolumes on the command line with the suffix %PVS,as a percentage of the remaining free space in the Volume Group with the suffix %FREE,or (for a snapshot) as a percentage of the total space in the Origin Logical Volume with the suffix %ORIGIN. The resulting value is rounded downward for the substraction otherwise it is rounded upward.-L,–size [+|-]LogicalVolumeSize[bBsSkKmMgGtTpPeE]
Change or set the logical volume size in units of megabytes. A size suffix of M for megabytes,G for gigabytes,T for terabytes,P for petabytes or E for exabytes is optional. With the + or – sign the value is added or subtracted from the actual size of the logical volume and rounded to the full extent size and without it,the value is taken as an absolute one.
