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
