xfs_estimate  -  estimate the space that an XFS filesystem
       will take


SYNOPSIS

       xfs_estimate [ -h? ] [ -b blocksize ] [ -i logsize ]
                    [ -e logsize ] [ -v ] directory ...


DESCRIPTION

       For each directory argument,  xfs_estimate  estimates  the
       space  that  directory  would take if it were copied to an
       XFS filesystem.  xfs_estimate does not cross mount points.
       The following definitions are used:
              KB = *1024
              MB = *1024*1024
              GB = *1024*1024*1024

       The xfs_estimate options are:

       -b blocksize
              Use  blocksize  instead of the default blocksize of
              4096 bytes.  The modifier k can be used  after  the
              number  to  indicate  multiplication  by 1024.  For
              example,

                   xxffss_eessttiimmaattee --bb 6644kk //

              requests an estimate of the space required  by  the
              directory  / on an XFS filesystem using a blocksize
              of 64K (65536) bytes.

       -v     Display more information, formatted.

       -h     Display usage message.

       -?     Display usage message.

       -i, -e logsize
              Use logsize instead of the default log size of 1000
              blocks.   -i  refers  to  an internal log, while -e
              refers to an external log.  The modifiers  k  or  m
              can  be used after the number to indicate multipli­
              cation by 1024 or 1048576, respectively.

              For example,

                   xxffss_eessttiimmaattee --ii 11mm //

              requests an estimate of the space required  by  the
              directory  / on an XFS filesystem using an internal
              log of 1 megabyte.


EXAMPLES

       % xxffss_eessttiimmaattee --ee 1100mm //vvaarr//ttmmpp

               with the external log using 2560 blocks or about 10.0 megabytes

       % xxffss_eessttiimmaattee --vv --ee 1100mm //vvaarr//ttmmpp
       directory                     bsize   blocks    megabytes    logsize
       /var/tmp                       4096      792        4.0MB   10485760

       % xxffss_eessttiimmaattee --vv //vvaarr//ttmmpp
       directory                     bsize   blocks    megabytes    logsize
       /var/tmp                       4096     3352       14.0MB   10485760

       % xxffss_eessttiimmaattee //vvaarr//ttmmpp
       /var/tmp will take about 14.0 megabytes
