NAMExfs_estimate − estimate the space that an XFS filesystem will take
SYNOPSISxfs_estimate [ −h ] [ −b blocksize ] [ −i logsize ]
[ −e logsize ] [ −v ] directory ...
xfs_estimate −V
DESCRIPTIONFor 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, \f4xfs_estimate \-b 64k /\f1 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. −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, \f4xfs_estimate \-i 1m /\f1 requests an estimate of the space required by the directory / on an XFS filesystem using an internal log of 1 megabyte. −V Print the version number and exits.
EXAMPLES% \f4xfs_estimate \-e 10m /var/tmp\f1\f7
/var/tmp will take about 4.2 megabytes
with the external log using 2560 blocks or about 10.0 megabytes% \f4xfs_estimate \-v \-e 10m /var/tmp\f1\f7
directory bsize blocks megabytes logsize
/var/tmp 4096 792 4.0MB 10485760% \f4xfs_estimate \-v /var/tmp\f1\f7
directory bsize blocks megabytes logsize
/var/tmp 4096 3352 14.0MB 10485760% \f4xfs_estimate /var/tmp\f1\f7
/var/tmp will take about 14.0 megabytes 0
