extendfs_vxfs(1m) [hpux man page]

extendfs_vxfs(1M)														 extendfs_vxfs(1M)

NAME

       extendfs_vxfs: extendfs - extend VxFS file system size

SYNOPSIS

       size] special

DESCRIPTION

       If  the	VxFS file system image created on special does not use all of the available space, increases the capacity of a VxFS file system by
       updating the file system structure to include the extra space.

       special specifies the device special file of either a logical volume or a disk partition.  If special refers to a mounted file system,  you
       must unmount special before running (see mount(1M)).

       The Version 5 disk layout supports file systems up to 32 terabytes.  The size to which a Version 5 disk layout file system can be increased
       depends on the file system block size:

	    o  1024 bytes  4,294,967,039 sectors (4 TB)

	    o  2048 bytes  8,589,934,078 sectors (8 TB)

	    o  4096 bytes 17,179,868,156 sectors (16 TB)

	    o  8192 bytes 34,359,736,312 sectors (32 TB)

       The Version 6 disk layout supports file systems up to 256 terabytes.  The size to which	a  Version  6  disk  layout  file  system  can	be
       increased depends on the file system block size:

	    o  1024 bytes  34,359,736,312 sectors (32 TB)

	    o  2048 bytes  68,719,472,624 sectors (64 TB)

	    o  4096 bytes 137,438,945,248 sectors (128 TB)

	    o  8192 bytes 274,877,890,496 sectors (256 TB)

       The  maximum file system size supported is 2 terabytes.	For a file system's size to be increased to 32 terabytes or greater, the file sys-
       tem must be on a 64-bit kernel operating system and must reside on a VERITAS Volume Manager volume.

       If the file system resides on a volume set, will fail.  Use the fsvoladm(1M) command to extend a multi-volume file system.

       When the file system size is grown with the extendfs command, the intent log size is not automatically increased.

   Options
       recognizes the following options:

	      Specify the VxFS file system type.

	      Query	special to determine the size.	The file system is not extended.

	      Specify the number of
			blocks to add to the file system.  If size is omitted, the maximum possible size is used.

	      Specify verbose mode, which displays the resulting size of file system
			along with output of the newly sized file system.  Without there is no output.

   Operands
       recognizes the following operand:

	      special	The device special file of either a logical volume or a disk partition.  If special refers to a mounted file  system,  you
			must unmount special before running (see mount(1M)).

EXAMPLES

       This example shows how to increase the capacity of a file system created on a logical volume.

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:
