NAME

       fsvoladm - VxFS volume administration utility

SYNOPSIS

       [bias]

DESCRIPTION

       The  utility  performs administrative tasks, such as adding, removing, resizing, and encapsulating volumes in a specified VERITAS File Sys-
       tem.  mount_point specifies the directory on which the file system is mounted.

       volname specifies the volume within the volume set.

       By default, size, bias, and newsize are specified in units of disk blocks bytes).  However, you can append or to  the  number  to  indicate
       that the value is in kilobytes, megabytes, gigabytes, or terabytes, respectively.

   Keywords
       Adds a volume to a file system.	The new space is available for allocation.

       Removes an encapsulated volume from a file system
	      and restores the original contents of the volume.  This operation can fail if there were significant changes to a file's allocations
	      on disk since encapsulation.  A volume encapsulated with a bias cannot be deencapsulated.

       Adds a volume to a file system,
	      making the contents of that volume, starting from offset bias, available as a file instead of free space.

	      The size of the encapsulated file is size - bias.  bias must be smaller than size, and be a multiple of the file system block size.

	      The default value of bias is 0.

       Displays the volumes in a file system.

       Removes a volume from a file system.

       Resizes one of the volumes in a file system.
	      In some circumstances, the command cannot resize a 100% full file system due to lack of space for updating structural information.

	      Check VxFS file systems on a regular basis; increase their size if they approach 100% capacity.  This problem can also occur if  the
	      file system is very busy.  Free up space or reduce activity on the file system and try the resize again.

EXAMPLES

       The following command adds the volume that is 10 gigabytes in size, to the file system

       The following command removes the volume from the file system

       The following command resizes the volume in the file system from its current size to 20 GB:

       The following command displays the volumes in the file system

       The following command encapsulates the volume The volume is ten gigabytes in size, resides in the file system and has the file name

       The following command de-encapsulates the volume that was encapsulated in the previous example:

NAME

       vgexport - export an LVM volume group and its associated logical volumes

SYNOPSIS

       mapfile] outfile] vg_name

       mapfile vg_name

DESCRIPTION

       Using  the  format  of  the  first command line of the above, the command can be used to remove a volume group from the system.	The volume
       group will be removed without modifying the logical volume information found on the physical volumes.

       The volume group identified by vg_name is removed from the or file, and the associated device files including  the  vg_name  directory  and
       file are removed from the system.

       The  volume group information and data is untouched on the physical volume.  These disks can be imported to another system with the command
       (see vgimport(1M)).

   Scan Option
       Using the format of the second command line of the above, the command generates a mapfile that can be copied to other systems that are part
       of a high availability cluster (use the option if you do not want to remove the volume group from the system the command is being run from)
       and the command (see vgimport(1M)) can be used to recreate the volume group.  See also vgchange(1M).  The mapfile contains a description of
       the  volume group and its associated logical volume(s) (if any).  The logical volume information found on the physical volumes is not modi-
       fied.

   Options and Arguments
       recognizes the following options and arguments:

	      vg_name	     The path name of the volume group.

	      By default, a file named
			     is created in the current directory.  This file contains a description of the volume group and its associated logical
			     volume(s)	(if  any).   Use  this option to specify a different name for the file, mapfile.  This file can be used as
			     input to (see vgimport(1M)).  When used with the option, the volume group specified in the mapfile can be shared with
			     other systems in the high availability cluster.

	      Preview the actions to be taken but do not update the
			     or file or remove the devices file.  This option is best used in conjunction with the option.

	      Print verbose messages
			     including the names of the physical volumes associated with this volume group.

	      Scan option.   When the option is specified, then the options must also be specified.  A mapfile is created that can be used to cre-
			     ate volume group entries on other systems in the high availability cluster (with the command).

	      Write the current set of
			     pv_paths for the volume group to the outfile.  The outfile may then be used as the infile for the	option.   If  used
			     together  with  the option the volume group is not exported but the list of pv_paths is still written to the outfile.
			     This may be useful to derive a list of pv_paths for the volume group or to use on another system which is sharing the
			     volume group and which has an identical configuration.

EXTERNAL INFLUENCES

   Environment Variables
       determines the language in which messages are displayed.

       If is not specified or is null, it defaults to "C" (see lang(5)).

       If any internationalization variable contains an invalid setting, all internationalization variables default to "C" (see environ(5)).

EXAMPLES

       Export the volume group into mapfile The volume group will be removed from the exporting system.

       Export the volume group and write the disk names into the file

       Create  a  mapfile to be copied to other systems in a high availability cluster to build the volume group information for the volume group,
       Note that the volume group is not removed from the exporting system.  The importing systems will create the volume group with  the  command
       using the and options.
