So far our development team has reported an improvement in the frequency of the I/O Errors but still not enough for them to be 100% happy. </div><div><br></div><div>In the mean time i've been double checking all the settings and understanding the timeouts etc. As we use software RAID on the OSTs I've made sure that the setup of these are as the operations manual states. </div><div><br></div><div>My next port of call is going to be to update the bnx2x driver that our BCM57711 10Gig Ethernet cards use on all the clients and MDT/OSTs. I doubt that its going to make a difference but the version of the driver is the CentOS 5.4 driver.</div><div><br></div><div>I have also had a snoop round the switch to make sure there isn't any funny setting floating round that could also be the cause of the problem.</div><div><br></div><div>Any thoughts?</div><div><font class="Apple-style-span" face="Tahoma, Verdana, Helvetica, Arial" size="3"><span class="Apple-style-span" style="font-size: 13px;"><font class="Apple-style-span" face="Helvetica"><span class="Apple-style-span" style="font-size: medium;"><br></span></font></span></font></div><div>Regards, </div><div><br></div><div><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><span class="Apple-style-span" style="font-family: Helvetica; "><div><span class="Apple-style-span" style="font-family: Tahoma, Verdana, Helvetica, Arial; font-size: 13px; ">Peter Kitchener<br>Systems Administrator<br>Capital Markets CRC Limited (CMCRC)<br>Telephone: +61 2 8088 4223<br>Fax: +61 2 8088 4201<br><font color="#0000ff"><a href="http://www.cmcrc.com/" target="_blank">www.cmcrc.com</a></font> <br><br> <br></span></div></span><span></span></span><br class="Apple-interchange-newline"><span><img height="87" width="253" id="4ae168a9-59b7-4692-bb07-e4f8a396a3d1" apple-width="yes" apple-height="yes" src="cid:68C0C3AE-66F9-4BC4-A9DF-522D47B4E092@staff.cmcrc.com"></span><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><span class="Apple-style-span" style="font-family: Tahoma, Verdana, Helvetica, Arial; font-size: 13px; "><br class="Apple-interchange-newline"><br>Capital Markets CRC Ltd - Confidential Communication<br>The information contained in this e-mail is confidential.
