[CentOS-virt] Boot from SCSI in HVM
Hello, I have to migrate 3 server based on debian from physical to Xen (fully virtualized). For doing this I use clonezilla. With vmware no problem, but when I restore image in Xen I have the problem that the HVM BIOS of CentOS 5.3 cannot boot from SCSI device (sda in my situation). If I set the virtual disk like hda no problem but the original disk was sda and I need to boot from sda. How can I do?

Si usas un proxy, es ilogico hacer nat, de el mismo, ya que se supone que una de las interfaces tiene un IP publica. De hecho los proxy se colocan justamente para mejorar el trafico hacia el exterior y filtrar el contenido WEB, solo el proxy deberia poder efectuar cosultas hacia el exterior, y procesar las perticiones de las maquinas de la LAN. _ Walter Cervini movil: 0424-1543350 0412-2042186 Pin: 20911CF3 El 17 de julio de 2009 14:36, ces can arvega...@hotmail.com escribió: lo que pasa es lo siguiente: si tu te conectas directamente a internet pasa esto: tu colocas www.google.com para resolver el nombre necesitaras de un servidor dns(puerto 53 udp) luego cuando halla resuelto la ip del lugar se conectara(puerto 80 tcp) ahora si usas un proxy transparente con dos interfaces de red una para internet y otra para tu lan: premisas:tu lan esta conectada a la interfaz eth0 y internet a eth1 tu colocas www.google.com para resolver el nombre necesitaras de un servidor dns(puerto 53 udp) si no has activado nat no se podra conectar al servidor dns salvo que lo tengas en la lan,ahora luego que ha resuelto la direccion ip necesitara conectarse mediante el puerto 80 a internet pero como tu proxy transparente esta configurado para que todo lo que ingrese por el puerto 80 lo reenvie al puerto 3128, el proxy analizara el contenido segun lo que hayas configurado, denegado o permitido, para ingresar a hotmail por ejemplo que usa http seguro(puerto 443 tcp) lo hara directamente sin uso de proxy espero hallas entendido.

creo que tienes que ver que el proxy tiene dos interfaces y esta activado el modo transparente(de ahí su nombre), osea no tienes que ir a configurar en el navegador el servidor proxy.

The idea of intentionally skewing the system clock and wait for a reaction was my next step, but since it stopped restarting I cannot verify anything now.

If I run rsync now, however, it is trying to copy over all the files since none exist on the local servers, and by my calculations copying that 160gb worth of data should be done some time in mid-February, 2010. I can make the 4-hour round trip out to the remote site with a USB hard drive and copy the files that way, but my concern is how to get the file structure, timestamps, permissions, etc copied exactly from the remote server USB drive local server so that rsync can run most efficiently (and not have to do a compare on every single file the first time it runs.) So the question is, how do I copy the files from the remote server back to my local server in a way that will allow rsync, once the copy is complete, to start dealing just with the daily changes in the most efficient way possible?

[CentOS] OT: Web Project type software
On Wed Jul 15 18:37:03 UTC 2009, James Pifer jep at obrien-pifer.com wrote: Sorry for the OT... I'm looking for some software to fill a fairly specific set of requirements. I'm not necessarily looking for project software, but it seems like the closest to match what I need. I'm also not tied into open source or free. If anyone knows of any software that might fill these requirements I would appreciate it. I am building a fairly sizable dbms based project and I started out with subversion as the SCM and Trac as the PAS. Last year I switched the project to Git and Redmine respectively. Both are open source. Git is the Linux kernel maintainers' SCM system and was initially designed and written by LT himself to replace BitKeeper. It is a completely distributed SCM and is very easy to use, albeit not so easy to learn or understand. Here's what I'm looking for: 1) Web enabled application Redmine is 100% Ruby and Rails, totally web based. It supports Git repositories out of the box. Git is a combination of scripts and C programs. It is available for Linux, Microsoft and several other OS platforms. Repository structure is identical for all platforms although differs in implementation details. On MicroSoft environments I hold that Git is best hosted under a cygwin instance, although a native port does exist. 2) File storage - need to stare a large amount of large cad files - be able to categorize file storage (not one large list) - keep different revisions of files with some kind of notes - be able to search files (at least include names in a search) Remine uses the underlying fs for file storage and provides the metadata for search. Files can be placed into a document list or attached to individual wiki pages. A description can be provided upon creation, although at present there seems no supported way of editing an existing description. Redmine supports full test searching. However, Git is by far and away the best solution to the problem of large file storage. Redmine can index a Git repository and track individual change sets. Therefore, Git + Redmine will give you most, if not all, of what you ask for. 3) Task - assign and keep track of tasks (searchable) Redmine supports multiple projects and sub-projects in a single instance. Issues may be related to one another. Users may be assigned differing roles on different projects. Different projects can have different categories and statuses. The DBMS backend is PostgrSQl so any report writer with an SQL backend should be able to provide whatever reports that you have the data to drive. 4) Store meeting notes and minutes (searchable) In addition to issue tracking and file storage, Redmine provides both project specific wikis and web forums. Access to either can be controlled on a project/user basis. The full text search facility covers both. It also has time logging and a slew of other features. 5) Would like to support LDAP I believe that Redmine does, but I do not use this myself so I cannot be sure. Git is a filesystem, it has its own network transfer protocol which is very fast and completely insecure. It also supports transfer over http, very slow and insecure, and ssh, acceptable speed and secure transfer. 6) Extension on file storage - since we'll be storing a large files and many of our users are across a WAN we'd like to sync/mirror the files to a few different servers. I'm not sure how we'd control how the users get the closest server but If you use Git instead of Redmine for your large file store then each user gets a complete repository the first time that they pull (clone actually) from the remote, including all the source changes to initialisation. Thereafter they only get the diff objects. Git uses a very efficient storage mech. that basically only passes compressed diffs of file contents. It uses MD5 hashes of file contents to identify change sets so that if you rename a file or merge two into one it can track these events and avoid duplicate storage. I use a cron scheduled git pull over ssh to maintain a remote copy of our base repository and the traffic created is negligible even after large commits. If the Git repository containing those files is bound to your Redmine project then you can search the files therein through Redmine and compare diffs across multiple versions. Of course, nothing is going to help much with binary data files. HTH -- *** E-Mail is NOT a SECURE channel *** James B.

Login to the iLO/iLO2 interface and look at the system event log, all DL585s will log memory errors there, and will even tell you what memory module it is. In addition to Nate's suggestion, you may be able to use the mcelog utility to check for CPU and memory faults: http://prefetch.net/blog/index.php/2009/06/11/locating-hardware-faults-on-linux-servers/ Hope this helps, - Ryan -- http://prefetch.net ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Upgrade 4.7 5.3 poorer 'performance'

Re: [CentOS] My server reboots every hour! Help please!
Base on last output, I would start to look on the process that was invoke by ljubica and vmarko, you might find something from there. Anyways, is your server running any DB process? You might also look at the server history on when this problem start to happened and investigate any updates that you or the others have done prior to the problem. SAR command can help.

Re: [CentOS] passing alias addresses
Jerry Geis wrote: hi all, When using the alias address scheme, like eth1:0 on a machine ... things are working. When that interface is disabled on box A and becomes active on box B what should Box B do to correctly update the ARP tables external to box B so the external world knows how to get to the new destination and not the old box A? Hosts on the same subnet usually figure this out quickly, but routers may cache arp values for 20 minutes or so. If you are doing this to move a service to keep it highly available, you might like the 'heartbeat' package which will takes care of the details of moving an IP address for you. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
