[CentOS-virt] Simulate Network Cable Disconnect
Hello All, I am having trouble simulating a network cable disconnect with KVM. I would like to test active backup bonding for a switch IOS upgrade in a production environment. Basically I have the VM running on a bridged network which is also tied into GNS3 simulating a small-scale version of the production environment. I have tried bringing down the vnetX interface and the actual virtual network itself (virbrX) with no luck. Has anyone had to do this before/maybe knows some tips? If more info is required about my setup, I can give it. Thanks! Tait ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

[CentOS-es] Optimizar el proceso building file list de Rsync
Hola, Estoy utilizando un script que hace uso de rsync para mover entre 1-2 millones de ficheros entre 2 máquinas, dividido en 2 fases: 1) Una primera ejecución para migrar el grueso de los datos, se copiarán los 1-2 millones de ficheros y se asume que el proceso durará entre 3-4 horas aprox. 2) Segunda ejecución del script, donde se sincronizaran las diferencias desde la primera ejecución. El problema de este escenario es que rsync se tira entre 15 y 20 minutos construyendo el listado de ficheros a sincronizar (proceso building file list), un tiempo que me gustaría reducir al máximo posible al menos en la fase 2) del script, la del 1) no me importa :) El motivo es que desde que lanzo el primer rsync hasta que se lanza el segundo, apenas se han modificado/creado/borrado 1000-2000 ficheros y es ¿Conoceís alguna alternativa a rsync para este escenario?

Check inode availability as well. If you're out of inodes, you won't be able to create a file. You can also look at your `limit' output. Maybe one of those limits (most possible `filesize' or `descriptors') exceeded. Can try vim -n (won't create swap file.)

[CentOS] dhclient.conf being ignored!
It seems that the prominent North American Enterprise Linux vendor has decided that dhclient.conf should be ignored, i.e. ifup-eth causes dhclient to be called with -cf /etc/dhclient-$(DEVICE).conf, and then ifup-eth/ifdown-eth wipes the file out each time. Through the use of DHCP_HOSTNAME in ifcfg-eth0 you can specify a host name, but because of the above behavior of ifup-eth other options don't seem to be able to be passed to dhclient. I tried placing supersede ntp-servers into dhclient-up-hooks, but that also seems to be ignored, and my google fu seems to be failing on how to build dhclient-enter-hooks for the purpose (if that would even help). anyone got better suggestions than: a) mod /etc/sysconfig/network-scripts/ifup-eth to build /etc/dhclient-$(DEVICE).conf combining the options I want. b) brute forcing things with `chattr +i /etc/ntp.conf` -- Todd Denniston Crane Division, Naval Surface Warfare Center (NSWC Crane) Harnessing the Power of Technology for the Warfighter ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] heartbeat package in extras trouble with 5.4

Re: [CentOS] question on sendmail.mc file
Using a trap-all user may seem like a good method to prevent spammers from determining what user accounts are on a system, but will also trap legitimate mail sent to an incorrect address (e.g. via a typo on the username). I would only user a trap-all on an entire domain dedicated to the purpose. I have always found that there are better methods to decrease spamming (e.g. grey listing, greet pause, mimedefang). However, if you really need to you coud try define(`LUSER_RELAY',`local:someu...@your.domain') Remember too, that user MUST exist!

Does anyone have any suggestions on how to get heartbeat working again? Running heartbeat on Centos 5.4 here without a problem. Just powered up my test cluster and made sure system was up-to-date using yum. Heartbeat started without a problem. Perhaps you have selinux enabled on the system? Can you try disabling selinux? This may sound like a half-hearted attempt to 'repair' the issue, but try backing up your authkeys, ha.cf and haresources on each host and try removing and reinstalling the packages. At this point you have nothing to lose since the daemons will not start. -- Ryan Manikowski ]] Devision Media Services LLC [[ www.devision.us r...@devision.us | 716.771.2282 ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
