<a name="NAME"></a><h2>NAME</h2><p><font size=3>xfs_estimate - estimate the space that an XFS filesystem will take</p>
<a name="SYNOPSIS"></a><h2>SYNOPSIS</h2><p><font size=3><B>xfs_estimate</B> <font size=3>[ <font size=3><B>-h?</B> <font size=3>] [ <font size=3><B>-b</B> <font size=3>blocksize ] [ <font size=3><B>-i</B> <font size=3>logsize ] [ <font size=3><B>-e</B> <font size=3>logsize ] [ <font size=3><B>-v</B> <font size=3>] directory ...</p>
<a name="DESCRIPTION"></a><h2>DESCRIPTION</h2><p><font size=3>For each <font size=3><I>directory</I> <font size=3>argument, <font size=3><I>xfs_estimate</I> <font size=3>estimates the space that directory would take if it were copied to an XFS filesystem. <font size=3><I>xfs_estimate</I> <font size=3>does not cross mount points. The following definitions are used:<br>
<span style=" text-indent: 1.3000in;"></span>KB = *1024<br>
<span style=" text-indent: 1.3000in;"></span>MB = *1024*1024<br>
<span style=" text-indent: 1.3000in;"></span>GB = *1024*1024*1024</p>
<p><font size=3>The <font size=3><I>xfs_estimate</I> <font size=3>options are:</p>

<table width="100%"  rules="none"  frame="none"  cols="3">

<p><font size=3>Use <font size=3><I>blocksize</I> <font size=3>instead of the default blocksize of 4096 bytes. The modifier <font size=3><B>k</B> <font size=3>can be used after the number to indicate multiplication by 1024. For example,</p>
<p><span style=" text-indent: 0.5000in;"></span><font size=3><EM>xfs_estimate -b 64k /</p>
</EM><p><font size=3>requests an estimate of the space required by the directory / on an XFS filesystem using a blocksize of 64K (65536) bytes.</p>

<p><font size=3>Use <font size=3><I>logsize</I> <font size=3>instead of the default log size of 10 MB. <font size=3><B>-i</B> <font size=3>refers to an internal log, while <font size=3><B>-e</B> <font size=3>refers to an external log. The modifiers <font size=3><B>k</B> <font size=3>or <font size=3><B>m</B> <font size=3>can be used after the number to indicate multiplication by 1024 or 1048576, respectively.</p>
<p><font size=3>For example,</p>
<p><span style=" text-indent: 0.5000in;"></span><font size=3><EM>xfs_estimate -i 1m /</p>
</EM><p><font size=3>requests an estimate of the space required by the directory / on an XFS filesystem using an internal log of 1 megabyte.</p>
