LVRESIZE(8) System Manager's Manual LVRESIZE(8) NAME lvresize - resize a logical volume SYNOPSIS lvresize [--alloc AllocationPolicy] [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [-i|--stripes Stripes [-I|--stripesize StripeSize]] {-l|--extents [+]LogicalExtentsNumber[%{VG|LV|PVS|FREE}] | -L|--size [+]LogicalVolumeSize[kKmMgGtT]} [-t|--test] [-v|--verbose] LogicalVol- umePath [PhysicalVolumePath...] DESCRIPTION lvresize allows you to resize a logical volume. Be careful when reduc- ing a logical volume's size, because data in the reduced part is lost!!! You should therefore ensure that any filesystem on the volume is shrunk first so that the extents that are to be removed are not in use. Resizing snapshot logical volumes (see lvcreate(8) for informa- tion about creating snapshots) is supported as well. But to change the number of copies in a mirrored logical volume use lvconvert(8). OPTIONS See lvm for common options. -l, --extents [+|-]LogicalExtentsNumber[%{VG|LV|PVS|FREE}] Change or set the logical volume size in units of logical ex- tents. 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 ex- pressed as a percentage of the total space in the Volume Group with the suffix %VG, relative to the existing size of the Logi- cal Volume with the suffix %LV, as a percentage of the remaining free space of the PhysicalVolumes on the command line with the suffix %PVS, or as a percentage of the remaining free space in the Volume Group with the suffix %FREE. -L, --size [+|-]LogicalVolumeSize[kKmMgGtTpPeE] Change or set the logical volume size in units of megabytes. A size suffix of M for megabytes, G for gigabytes, T for ter- abytes, P for petabytes or E for exabytes is optional. 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. -i, --stripes Stripes Gives the number of stripes to use when extending a Logical Vol- ume. Defaults to whatever the last segment of the Logical Vol- ume uses. Not applicable to LVs using the original metadata LVM format, which must use a single value throughout. -I, --stripesize StripeSize Gives the number of kilobytes for the granularity of the stripes. Defaults to whatever the last segment of the Logical Volume uses. Not applicable to LVs using the original metadata LVM format, which must use a single value throughout. StripeSize must be 2^n (n = 2 to 9) SEE ALSO lvm(8), lvconvert(8), lvcreate(8), lvreduce(8), lvchange(8) Sistina Software UK LVM TOOLS 2.02.44-cvs (02-17-09) LVRESIZE(8)
