    SYNOPSIS

           lvextend  [--alloc AllocationPolicy] [-A|--autobackup y|n] [-d|--debug]
           [-h|-?|--help] [--noudevsync]  [-i|--stripes  Stripes  [-I|--stripesize
           StripeSize]]             {-l|--extents            [+]LogicalExtentsNum-
           ber[%{VG|LV|PVS|FREE|ORIGIN}] | -L|--size [+]LogicalVolumeSize[bBsSkKm-
           MgGtTpPeE]}  [-t|--test] [-v|--verbose] LogicalVolumePath [PhysicalVol-
           umePath[:PE[-PE]]...]
    
    
    

    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.
    
           --noudevsync
                  Disable  udev  synchronisation.  The  process  will not wait for
                  notification from udev.  It will continue  irrespective  of  any
                  possible udev processing in the background.  You should only use
                  this if udev is not running or has rules that ignore the devices
                  LVM2 creates.
    
           -l, --extents [+]LogicalExtentsNumber[%{VG|LV|PVS|FREE|ORIGIN}]
                  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, rel-
                  ative 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, as a percentage  of  the  remaining
                  free  space in the Volume Group with the suffix %FREE, or (for a
                  snapshot) as a percentage of the total space in the Origin Logi-
                  cal Volume with the suffix %ORIGIN.
    
           -L, --size [+]LogicalVolumeSize[bBsSkKmMgGtTpPeE]
                  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
    
           "lvextend -L+16M vg01/lvol01 /dev/sda:8-9 /dev/sdb:8-9"
           tries  to  extend a logical volume "vg01/lvol01" by 16MB using physical
           extents /dev/sda:8-9 and /dev/sdb:8-9 for allocation of extents.
