NAME

       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,

                   xfs_estimate -b 64k /

              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
              multiplication by 1024 or 1048576, respectively.

              For example,

                   xfs_estimate -i 1m /

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

EXAMPLES

       % xfs_estimate -e 10m /var/tmp
       /var/tmp will take about 4.2 megabytes
               with the external log using 2560 blocks or about 10.0 megabytes

       % xfs_estimate -v -e 10m /var/tmp
       directory                     bsize   blocks    megabytes    logsize
       /var/tmp                       4096      792        4.0MB   10485760

       % xfs_estimate -v /var/tmp
       directory                     bsize   blocks    megabytes    logsize
       /var/tmp                       4096     3352       14.0MB   10485760

       % xfs_estimate /var/tmp
       /var/tmp will take about 14.0 megabytes

                                                               xfs_estimate(8)
