How to resize an LVM logical volume?
To adjust the LVM logical volume size, you must first confirm the file system type and support status before operation. ext4 supports online expansion and shrinkage (need to be unmounted or read-only mounted), xfs only supports online expansion; if there is no remaining space for the volume group during expansion, you need to add a physical volume and expand the volume group first, then use lvextend to expand the logical volume and adjust the file system; shrink the logical volume, you must unmount the file system, check and shrink the file system, and then shrink the logical volume, and finally remount it. The order cannot be reversed, otherwise data corruption may be caused.
