<p>created</p> <p><b>New page</b></p><div>The I/O limit feature is available in OpenVZ since kernel &lt;code&gt;2.6.32-042stab084.3&lt;/code&gt; and [[vzctl]] &lt;code&gt;4.6&lt;/code&gt;. This feature allows to limit disk I/O bandwidth available to a container.<br /> <br /> == Example ==<br /> <br /> root@host# vzctl set 777 --iolimit 3M --save<br /> Setting iolimit: 3145728 bytes/sec<br /> CT configuration saved to /etc/vz/conf/777.conf<br /> <br /> root@host# vzctl enter 777<br /> root@CT:/# cat /dev/urandom | pv -c - &gt;/bigfile3<br /> 39.1MB 0:00:10 [ 3MB/s] [ &lt;=&gt; ]<br /> ^C<br /> <br /> == Details ==<br /> <br /> Limit works for reading and writing. There is also a burstable limit which allows 3x normal limit for a very short time.<br /> <br /> == See also ==<br /> * {{Man|vzctl|8}}, I/O scheduling<br /> * [[http://openvz.livejournal.com/45831.html OpenVZ blog: Yay to I/O limits!]<br /> * [[I/O priorities]]<br /> * [[IO accounting]]<br /> <br /> [[Category: Resource management]]<br /> [[Category: HOWTO]]</div>
