    vgcreate

    
    
    

    SYNOPSIS

           vgcreate  [--addtag  Tag]  [--alloc  AllocationPolicy] [-A|--autobackup
           {y|n}] [-c|--clustered {y|n}] [-d|--debug]  [-h|--help]  [-l|--maxlogi-
           calvolumes  MaxLogicalVolumes]  [-M|--metadatatypetype] [-p|--maxphysi-
           calvolumes MaxPhysicalVolumes] [-s|--physicalextentsize PhysicalExtent-
           Size[bBsSkKmMgGtTpPeE]] [-t|--test] [-v|--verbose] [--version] [ PHYSI-
           CAL DEVICE OPTIONS ] VolumeGroupName PhysicalDevicePath  [PhysicalDevi-
           cePath...]
    
    
    

    DESCRIPTION

           vgcreate  creates  a  new volume group called VolumeGroupName using the
           block special device PhysicalDevicePath.
    
           If PhysicalDevicePath was not previously configured for LVM with pvcre-
           ate  (8),  the  device will be initialized with the same default values
           used with pvcreate.  If non-default pvcreate values  are  are  desired,
           they may be given on the commandline with the same options as pvcreate.
           See PHYSICAL DEVICE OPTIONS  for  available  options.   Note  that  the
           restore-related  options  such  as  --restorefile, --uuid, and --physi-
           calvolumesize are not available.  If a restore operation is needed, use
           pvcreate (8) and vgcfgrestore (8).
    
    
    

    OPTIONS

           See lvm for common options.
    
           -c, --clustered {y|n}
                  If  clustered  locking is enabled, this defaults to y indicating
                  that this Volume Group is shared with other nodes in  the  clus-
                  ter.
    
                  If  the  new Volume Group contains only local disks that are not
                  visible on the other nodes, you must specify --clustered n.   If
                  the  cluster  infrastructure is unavailable on a particular node
                  at a particular time, you may still be able to use  such  Volume
                  Groups.
    
           -l, --maxlogicalvolumes MaxLogicalVolumes
                  Sets  the maximum number of logical volumes allowed in this vol-
                  ume group.  The setting can be changed with vgchange.  For  vol-
                  ume  groups  with metadata in lvm1 format, the limit and default
                  value is 255.  If the metadata uses  lvm2  format,  the  default
                  value  is  0  which  removes  this restriction: there is then no
                  limit.
    
           -p, --maxphysicalvolumes MaxPhysicalVolumes
                  Sets the maximum number of physical volumes that can  belong  to
                  this  volume  group.   The setting can be changed with vgchange.
                  For volume groups with metadata in lvm1 format,  the  limit  and
                  default  value  is  255.   If the metadata uses lvm2 format, the
                  default value is 0 which removes this restriction: there is then
                  no  limit.   If you have a large number of physical volumes in a
                  volume group with metadata in lvm2 format, for tool  performance
    
                  If  the volume group metadata uses lvm1 format, extents can vary
                  in size from 8KB to 16GB and there is a limit of  65534  extents
                  in  each logical volume.  The default of 4 MB leads to a maximum
                  logical volume size of around 256GB.
    
                  If the volume group metadata uses lvm2 format those restrictions
                  do  not  apply,  but  having a large number of extents will slow
                  down the tools but have no impact on I/O performance to the log-
                  ical volume.  The smallest PE is 1KB.
    
                  The 2.4 kernel has a limitation of 2TB per block device.
    
    
    

    PHYSICAL DEVICE OPTIONS

           The  following  options are available for initializing physical devices
           in the volume group.  These options are further described in the pvcre-
           ate man page.
    
           -f, --force
    
           -y, --yes
    
           -Z, --zero y|n
    
           --labelsector sector
    
           --metadatasize size
    
           --pvmetadatacopies copies
    
           --dataalignment alignment
    
           --dataalignmentoffset alignment_offset
    
    
    

    EXAMPLES

           To   create  a  volume  group  named  test_vg  using  physical  volumes
           /dev/sdk1, and /dev/sdl1 with default physical extent size of 4MB:
    
                vgcreate test_vg /dev/sdk1 /dev/sdl1
