cpuspeed causing high load average?
by tony＠softins.co.uk 16 May '12

16 May '12

On a new server's CentOS5 install, with nothing in the way of applications running yet, I noticed that the load average was sitting between 2 and 5 all the time, even though top told me CPU was 100% idle. Eventually I found that stopping the "cpuspeed" subsystem allowed the load average to drop down to near zero, as I would expect it to be. I have the default /etc/sysconfig/cpuspeed with no customizations. Is the above behaviour expected? It seems wrong to me. Is cpuspeed broken? I did notice that with cpuspeed running, the CPUs were running at their minimum frequency of 1.6GHz, and after stopping the cpuspeed service they went up to their maximum speed of 2.8GHz. The system has a pair of E5660 Xeons, which Linux reports as 24 CPUs!

Sendmail problem - baffled
by Jussi Hirvi 16 May '12

16 May '12

Our backup mail server (which I have just re-configured) tries to contact the primary mail server, and fails. My log shows repeatedly "connection refused": May 15 22:21:41 mx2 sm-mta-rx[8674]: q4FIhPij007483: makeconnection (mail.greenspot.fi. [83.143.217.182]) failed: Connection refused by mail.greenspot.fi. May 15 22:21:41 mx2 sm-mta-rx[8674]: q4FIhPij007483: to=<myuser(a)mydomain.com>, delay=00:38:16, xdelay=00:00:00, mailer=esmtp, pri=10021795, relay=mail.greenspot.fi. [83.143.217.182], dsn=4.0.0, stat=Deferred: Connection refused by mail.greenspot.fi. But yet I can successfully telnet that host: # telnet mail.greenspot.fi 25 Trying 83.143.217.182... Connected to mail.greenspot.fi (83.143.217.182). Escape character is '^]'. 220 mail.greenspot.fi ESMTP Sendmail; Tue, 15 May 2012 22:34:22 +0300 Also, the mailer-daemon *can* send automatic warning messages to mail.greenspot.fi just fine. So, the error probably is in my sendmail configuration. The error appeared as I today reconfigured the backup mail server to use a "dual sendmail" setup with amavis and greylisting. How could I proceed? - Jussi

True bond howto for Centos 6
by aurfalien 15 May '12

15 May '12

Hi all, Read many posts on the subject. Using 802.3ad. Few problems; Cannot ping some hosts on the network, they are all up. Cannot resolve via DNS which is one of the hosts that I cannot ping, internal nor external DNS hosts. Unplugging the NICS and plugging them back in will then not allow pining if the default d=gateway. When cold booting it somewhat works, some hosts are pingable while others are not. When restarting the network service via /etc/init.d/network, nothing is pingable. Here are my configs; ifcfg-bond0 DEVICE=bond0 USERCTL=no BOOTPROTO=none ONBOOT=yes IPADDR=10.0.0.10 NETMASK=255.255.0.0 NETWORK=10.0.0.0 TYPE=Unknown IPV6INIT=no ifcfg-eth0 DEVICE=eth0 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes USERCTL=no ifcfg-eth1 DEVICE=eth1 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes USERCTL=no /etc/modprob.d/bonding.conf alias bond0 bonding options bond0 mode=5 miimon=100 Bonding worked great in Centos 5.x, not so well for me in Centos 6.2. My goal is to get this working under bridging for KVM, I can only imagine the nightmare seeing I can't get a simple bond to work! Any guidance is golden. - aurf

Excluding ConsoleKit in kickstart
by Dennis Jacobfeuerborn 15 May '12

15 May '12

Hi, I'm working on automating virtual machine installs using kickstart files and virt-install. The problem I have is that these kickstart installations install different packages than a minimal manual install. While I got rid of some of them I can't seem to prevent ConsoleKit from getting installed. I put "-ConsoleKit" in the packages section and later also added packages that require it but in the end it is still getting installed. Any ideas what I could do to stop it from being installed? Regards, Dennis

Nothing in el5 depends on the qt4-4.2.x that ships with el5. It's an old, rotten, and completely pointless package. Nothing of any interest could be build with it for years now, probably never ever was it of any use to anyone. I replaced it with a rebuild of qt4-4.6.2-20 from el6. This gives me a common and useable base for both el5 and el6. That could be a sensible approach for a krita.el5 package, too. -Michael
