xfs_info



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  pos­
              sible.  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 ext­
              size=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 contin­
              ues  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 max­
              pct=nn.

       -n     Specifies that no change to the filesystem is to be
              made.  The  filesystem  geometry  is  printed,  and
              /etc/mtab).   This  is  used  when   working   with
              filesystems  mounted  without  writing 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.  There­
       fore 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.
