xfs_estimate

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

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_esti-
       mate 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  multiplica-
	      tion 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
