lvreduce - Reduce the size of a logical volume
Shrinking is not supported on a GFS2 or XFS file system
Examples[edit]
Reduce to a total size of 1GB:
- TOTAL 1GB:
lvreduce --resizefs -L 1GB vg01/lvol1
Example: lvreduce --resizefs -L 4TB VG_NAME/LV_NAME Do you want to unmount "/srv" ? [Y|n] y fsck from util-linux 2.31.1 Resizing the filesystem on /dev/mapper/VG_NAME-LV_NAME to 1073741824 (4k) blocks. The filesystem on /dev/mapper/VG_NAME-LV_NAME is now 1073741824 (4k) blocks long. Size of logical volume VG_NAME/LV_NAME changed from <6.00 TiB (1572863 extents) to 4.00 TiB (1048576 extents). Logical volume VG_NAME/LV_NAME successfully resized.
