xfs_growfs(8)               System Manager's Manual              xfs_growfs(8)



NAME
       xfs_growfs, xfs_info - expand an XFS filesystem

SYNOPSIS
       xfs_growfs [ -dilnrxV ] [ -D size ] [ -e rtextsize ]
                 [ -L size ] [ -m maxpct ] [ -t mtab ]
                 [ -R size ] mount-point
       xfs_info [ -t mtab ] mount-point

DESCRIPTION
       xfs_growfs expands an existing XFS filesystem (see xfs(5)).  The mount-
       point argument is the pathname of the directory where the filesystem is
       mounted.   The  filesystem  must be mounted to be grown (see mount(8)).
       The existing contents of the filesystem are undisturbed, and the  added
       space becomes available for additional file storage.

       xfs_info  is  equivalent to invoking xfs_growfs with the -n option (see
       discussion below).

       The options to xfs_growfs are:

       -d, -D size
              Specifies that the data section  of  the  filesystem  should  be
              grown.   If  the  -D  size  option is given, the data section is
              grown to that size, otherwise the data section is grown  to  the
              largest  size  possible.   The  size  is expressed in filesystem
              blocks.

       -e     Allows  the  real-time  extent  size  to   be   specified.    In
              mkfs.xfs(8) this is specified with -r extsize=nnnn.

       -i     The  new  log  is  an  internal  log  (inside the data section).
              [NOTE: This option is not implemented]

       -l, -L size
              Specifies that the log  section  of  the  filesystem  should  be
              grown,  shrunk,  or  moved.  If the -L size option is given, the
              log section is changed to be that size, if possible.   The  size
              is  expressed in filesystem blocks.  The size of an internal log
              must be smaller than the size of an allocation group (this value
              is printed at mkfs(8) time).  If neither -i nor -x is given with
              -l, the log continues to be  internal  or  external  as  it  was
              before.  [NOTE: These options are not implemented]

       -m     Specify  a  new value for the maximum percentage of space in the
              filesystem that can be allocated as inodes.  In mkfs.xfs this is
              specified with -i maxpct=nn.

       -n     Specifies  that  no change to the filesystem is to be made.  The
              filesystem geometry is printed, and argument  checking  is  per-
              formed, but no growth occurs.

       -r, -R size
              Specifies that the real-time section of the filesystem should be
              grown.  If the -R size option is given, the real-time section is
              grown  to that size, otherwise the real-time section is grown to
              the largest size possible.  The size is expressed in  filesystem
              blocks.   The filesystem does not need to have contained a real-
              time section before the xfs_growfs operation.

       -t     Specifies an alternate mount table file (default is  /etc/mtab).
              This is used when working with filesystems mounted without writ-
              ing to /etc/mtab file - refer to mount(8) for further details.

       xfs_growfs is most often used in conjunction with logical volumes  (see
       lvm(8)  ).   However,  it can also be used on a regular disk partition,
       for example if a partition has been enlarged while retaining  the  same
       starting block.

PRACTICAL USE
       Filesystems  normally  occupy all of the space on the device where they
       reside.  In order to grow a filesystem,  it  is  necessary  to  provide
       added  space  for  it  to occupy.  Therefore there must be at least one
       spare new disk partition available.  Adding the  space  is  often  done
       through the use of a logical volume manager.
