If so, I would strongly recommend replacing that channel with a combination of ol5_u11_base and ol5_u11_patch from ULN instead. Those two channels are significantly smaller and will be much easier for the client to rebuild during an rhn_check run.</div><div class=""><br class=""></div><div class="">Alternatively, you can bind mount /var/cache/yum to a RAM disk so that the disk usage is non-existant. This will also dramatically improve performance.</div><div class=""><br class=""></div><div class="">Hope that helps,</div><div class="">Avi</div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On 30 Mar 2016, at 8:13 PM, Malla Reddy Madupu <<a href="mailto:mmreddys@yahoo.com" class="">mmreddys@yahoo.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class=""><div style="background-color: rgb(255, 255, 255); font-family: HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif; font-size: 13px;" class=""><div id="yui_3_16_0_ym18_1_1459302323371_43610" class="">Hi Guys</div><div id="yui_3_16_0_ym18_1_1459302323371_43611" class=""><br class=""></div><div id="yui_3_16_0_ym18_1_1459302323371_43574" class="">Greatly appreciated for your time.</div><div id="yui_3_16_0_ym18_1_1459302323371_43612" class=""><br class=""></div><div id="yui_3_16_0_ym18_1_1459302323371_43641" class="">I have a issue during spacewalk client add to the spacewalk master server.</div><div id="yui_3_16_0_ym18_1_1459302323371_43613" class=""><br class=""></div><div id="yui_3_16_0_ym18_1_1459302323371_43614" class="">We have staging server where all the VMs are connected to the Oracle SAN storage (Entry Level)</div><div id="yui_3_16_0_ym18_1_1459302323371_43573" class=""><br class=""></div><div id="yui_3_16_0_ym18_1_1459302323371_43556" dir="ltr" class="">When i am trying to add the client to the spacewalk server, there's too much I/O generating the <b id="yui_3_16_0_ym18_1_1459302323371_43750" class="">rhn_check </b>process some times it's writing more than <b class="">50M </b>data, this process is mainly reading/ writing <b id="yui_3_16_0_ym18_1_1459302323371_43572" class="">kjournald and Audit</b>. because of this system process reached to 100% waiting 80%.
