<3>-b<1> <2>blocksize<1>

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,

<3>-i, -e<1> <2>logsize<1>

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,

 8v
% <4>xfs_estimate -e 10m /var/tmp<1><7>
/var/tmp will take about 4.2 megabytes
        with the external log using 2560 blocks or about 10.0 megabytes
