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 reducing 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 information 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 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, 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 terabytes, 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 Volume. 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. -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

lvextend - extend the size of a logical volume SYNOPSIS
lvextend [--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
lvextend allows you to extend the size of a logical volume. Extension of snapshot logical volumes (see lvcreate(8) for information to cre- ate 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}] Extend or set the logical volume size in units of logical extents. With the + sign the value is added to 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, of the remaining free space for the specified PhysicalVolume(s) 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] Extend 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 + sign the value is added to the actual size of the logical volume and with- out it, the value is taken as an absolute one. -i, --stripes Stripes Gives the number of stripes for the extension. Not applicable to LVs using the original metadata LVM format, which must use a sin- gle value throughout. -I, --stripesize StripeSize Gives the number of kilobytes for the granularity of the stripes. 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) Examples "lvextend -L +54 /dev/vg01/lvol10 /dev/sdk3" tries to extend the size of that logical volume by 54MB on physical volume /dev/sdk3. This is only possible if /dev/sdk3 is a member of volume group vg01 and there are enough free physical extents in it. "lvextend /dev/vg01/lvol01 /dev/sdk3" tries to extend the size of that logical volume by the amount of free space on physical volume /dev/sdk3. This is equivalent to specifying "-l +100%PVS" on the command line. SEE ALSO
