NAME

       vgchange - change attributes of a volume group

SYNOPSIS

       vgchange  [--addtag  Tag]  [--alloc  AllocationPolicy] [-A|--autobackup
       {y|n}]  [-a|--available  [e|l]  {y|n}]  [-d|--debug]   [--deltag   Tag]
       [-h|--help]         [--ignorelockingfailure]        [-l|--logicalvolume
       MaxLogicalVolumes]    [-P|--partial]     [-t|--test]     [-v|--verbose]
       [--version] [-x|--resizeable {y|n}] [VolumeGroupName...]

DESCRIPTION

       vgchange  allows  you  to  change  the attributes of one or more volume
       groups.    Its   main   purpose   is   to   activate   and   deactivate
       VolumeGroupName,  or  all  volume  groups  if  none is specified.  Only
       active volume groups are subject to changes and allow access  to  their
       logical volumes.  [Not yet implemented: During volume group activation,
       if vgchange recognizes snapshot  logical  volumes  which  were  dropped
       because  they  ran  out  of  space, it displays a message informing the
       administrator that such snapshots should be removed (see  lvremove(8)).
       ]

OPTIONS

       See lvm for common options.

       -A, --autobackup{y|n}
              Controls  automatic  backup  of  metadata after the change.  See
              vgcfgbackup (8).  Default is yes.

       -a, --available[e|l]{y|n}
              Controls the availability of the logical volumes in  the  volume
              group  for  input/output.   In  other  words,  makes the logical
              volumes known/unknown to the kernel.

              If clustered locking is enabled, add ā€™eā€™ to  activate/deactivate
              exclusively  on  one  node or ā€™lā€™ to activate/deactivate only on
              the local node.  Logical volumes with single-host snapshots  are
              always  activated  exclusively  because they can only be used on
              one node at once.

       -l, --logicalvolume MaxLogicalVolumes
              Changes  the  maximum  logical  volume  number  of  an  existing
              inactive volume group.

       -x, --resizeable{y|n}
              Enables or disables the extension/reduction of this volume group
              with/by physical volumes.

EXAMPLES

       To activate all known volume groups in the system:

            vgchange -a y

       To change the maximum number of  logical  volumes  of  inactive  volume
       group vg00 to 128.

            vgchange -l 128 /dev/vg00
