<a name="NAME"></a><h2>NAME</h2><p style="margin-left: 18%"><font size=3>quotacheck - scan a filesystem for disk usages</font></p>
<a name="SYNOPSIS"></a><h2>SYNOPSIS</h2><p style="margin-left: 18%"><font size=3><B>quotacheck</B></font> <font size=3>[&shy;g] [&shy;u] [&shy;v] &shy;a<br>
<B>quotacheck</B></font> <font size=3>[&shy;g] [&shy;u] [&shy;v] filesys ...</font></p>
<a name="DESCRIPTION"></a><h2>DESCRIPTION</h2><p style="margin-left: 18%"><font size=3><I>Quotacheck</I></font> <font size=3>performs a filesystems scan for usage of files and directories, used by either user or group. XFS filesystems are ignored by</font> <font size=3><I>quotacheck</I></font><font size=3>, since the XFS quota system is journalled and therefore inherently consistent.</font></p>
<p style="margin-left: 18%"><font size=3>The output is the quota file for the corresponding filesystem. By default the names for these files are:<br>
- A user scan:</font> <font size=3><I>quota.user<br>
</I>- A group scan:</font> <font size=3><I>quota.group</I></font></p>
<p style="margin-left: 18%"><font size=3>The resulting file consists of a</font> <font size=3><I>struct dqblk</I></font> <font size=3>for each possible id up to the highest existing uid or gid and contains the values for the disk file and block usage and possibly excess time for these values. ( for definitions of</font> <font size=3><I>struct dqblk</I></font> <font size=3>see</font> <font size=3><I>&lt;linux/quota.h&gt;</I></font> <font size=3>)</font></p>
<p style="margin-left: 18%"><font size=3><I>Quotacheck</I></font> <font size=3>should be run each time the system boots and mounts non&shy;valid filesystems. This is most likely to happen after a system crash.</font></p>
<p style="margin-left: 18%"><font size=3>The speed of the scan decreases with the number of directories increasing. The time needed doubles when disk usage is doubled as well. A 100 MB partition used for 94% is scanned in 1 minute, the same partition used for 50% is done in 25 seconds.</font></p>
