LVEXTEND(8) System Manager's Manual LVEXTEND(8) NAME 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 create 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 ex- tents. With the + sign the value is added to the actual size of the logical volume and without it, the value is taken as an ab- solute one. The number can also be expressed as a percentage of the total space in the Volume Group with the suffix %VG, rela- tive to the existing size of the Logical Volume with the suffix %LV, of the remaining free space for the specified PhysicalVol- ume(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 ter- abytes, P for petabytes or E for exabytes is optional. With the + sign the value is added to the actual size of the logical vol- ume and without 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 single 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 com- mand line.
