        "DESCRIPTION": {
            "content": "lvreduce  reduces  the  size of an LV. The freed logical extents are returned to the VG to be\nused by other LVs. A copy-on-write snapshot LV can also be reduced if less space is needed to\nhold COW blocks. Use lvconvert(8) to change the number of data images in a RAID  or  mirrored\nLV.\n\nBe  careful when reducing an LV's size, because data in the reduced area is lost. Ensure that\nany file system on the LV is resized before running lvreduce so that the removed extents  are\nnot in use by the file system.\n\nSizes  will  be rounded if necessary. For example, the LV size must be an exact number of ex‐\ntents, and the size of a striped segment must be a multiple of the number of stripes.\n\nIn the usage section below, --size Size can be replaced with --extents Number.  See both  de‐\nscriptions the options section.\n",
