Re: [CentOS-virt] Selecting raw logical volumes during guest VM creation
You can add additional lvs to your guest system as separate virtual hard drives, this is the way I know of to achieve what you are trying to do. Create additional virtual drives using the lvs you want as the storage, then attach them to the vm. Hope this helps. On Dec 7, 2011 7:43 PM, Jeff Boyce jbo...@meridianenv.com wrote: Greetings - I have stepped through the first guest OS installation (a testing VM) on my new server and have a technical question that I hope someone might be able to help me with. I have exhausted my google search ability and have not been able to find the details I am looking for. In general the question I am trying to answer is how to select and use multiple raw logical volumes when creating a new VM, rather than just a single raw logical volume (if it is possible). Here are the details... I have setup my hardware with a single volume group (vg_mei) encompassing my entire raid array. With this I set up my base OS (CentOS 6) for the purpose of managing the hardware and the few VMs that will be created (using KVM). Three LVs were created for the base OS (lv_hostroot, lv_hostswap, and lv_hostvar) to contain the appropriate parts of the base OS file system. As expected, /boot was located outside the volume group. In preparation for installing my testing VM, I created two more LVs (lv_testroot and lv_testvar) to contain the appropriate parts of the guest file system. Following the RHEL6 Virtualization Guide (Section 25.1.4 for using LVM-based Storage Pools) I successfully added all the logical volumes that had been created into the host storage pool. So when I start the Virt-Manager GUI and work through the five steps for creating a new VM (shown in Section 6.3 of the RHEL6 Virtualization Guide), Step #4 provides the option for creating or using existing storage for the VM. When I select the option to use managed or other existing storage then choose the browse button, I am given a dialog box that displays all LVs that I have previously created. At this point though I am only allowed to select a single LV to install the guest OS. So I chose the lv_testroot logical volume and the installation was able to be completed (there was a little manual intervention required during the OS installation partitioning layout in order to prevent nesting LVMs). But I am wondering if there is a way during Step #4 of the VM creation to pass multiple LVs to the system so that during the OS installation process you have all the LVs that you want for the partitioning layout. I assume that there is a way to add an LV to an existing VM after the guest OS is installed, then move portions of the file system over to the added LV. Following my example above, adding lv_testvar to the testing VM then move my /var directory over and add an entry in fstab to mount it at boot time. I am doing some google searching right now to try and verify the details on how to do this. I curious about the best way to do the VM setup since I will be creating a new VM for my Samba file server, which will also include the users home directories. So for the Samba VM I will create in advance LVs for /, /var, /home, and /sambashare. Also is it possible to likewise add an LV for /swap after the fact (or is it really needed anymore for something like a small file server)? I want to use raw LVs from my host system in order to be able to use the full capabilities of LVM for each of my guest VMs. I realize that this may create a number of LVs to manage, but I don't expect to have more than 4 VMs on this box and I have worked out a good naming scheme for the LVs in order to keep track of everything. Any technical help, or pointers to blogs or technical documents that I may have missed, is greatly appreciated. Thanks.

Re: [CentOS-es] Olvidar contrasña SMB immediatamente
Hola, Gracias por tu respuesta. Le 07/12/2011 16:18, carlos restrepo a écrit : yo controlaria el acceso a esos recursos con ACL'S. (Así aunque el recurso este visible no lo podra acceder y menos modificar). Exactamente eso es lo que hago. Cada usuario tiene permisos para entrar en su recurso compartido y no en otro. Sin embargo Nautilus no se desconecta del recurso compartido cuando expulsas el disco del Escritorio. Lo puedo ver con un netstat -an, hay dos conexiones por cada usuario que ha hecho login sobre el NAS (una al puerto 139 tcp y otra al 445 tcp). Si después de conectarte con varios logins a sus respectivos recursos compartidos haces (desde cualquier ventana de Nautilus) un smb://ip_NAS puedes entrar a todos los recursos compartidos a los que anteriormente has accedido. Ya le he dado muchas vueltas al tema e incluso he encontrado en https://bugzilla.gnome.org/ una entrada declarando este problema como un bug. Así que se me ocurrió probar con un CentOS 6 y el problema desaparece. Cuando te conectas a un recurso compartido puedes marcar la opción Olvidar inmediatamente en el momento que te pide la contraseña. Parece que es una cuestión relacionada con la versión de Gnome porque tengo un par de RHEL antiguos y hacen lo mismo (Gnome 2.16), en cambio los Debian 6 y el CentOS 6 (Gnome 2.30) ya no. -- Francesc Guitart Service CRI ENISE ___ CentOS-es mailing list CentOS-es@centos.org http://lists.centos.org/mailman/listinfo/centos-es
[CentOS-es] Balance de Carga
Hola Lista Tengo una red donde los usuarios se conectan a un firewall que redirecciona los pedidos a un squid que tiene una tarjeta de red en la red local y otra con IP real y de esa manera salen a Internet. Lo que quiero hacer es montar dos squid y que cada uno salga por un canal diferente (son dos canales)y que los pedidos de los usuarios se balanceen entre los dos canales. Además necesito que si un squid no está respondiendo por falla o algo parecido, los paquetes se redireccionen solo al que funciona correctamente. Existe alguna herramienta en Centos que se encargue de balancear los pedidos a uno u otro squid Gracias -- Rolando Romero Acosta ___ CentOS-es mailing list CentOS-es@centos.org http://lists.centos.org/mailman/listinfo/centos-es

[CentOS] Backup Redux
Hey folks, I just went through the archives to see what people are doing for backups, and here is what I found : - amanda - bacula - BackupPC - FreeNAS Here is my situation : we have pretty much all Sun hardware with a Sun StorageTek SL24 tape unit backing it all up. OSes are a combination of RHEL and CentOS. The software we are using is EMC NetWorker Management Console version 3.5.1.Build.269 based on NetWorker version 7.5.1.Build.269 The pickle we are in right now is that this software is Java based, and stops working at a very specific release of JRE (1.6.26 or something like that). We still have some machines around with that release and it looks like we need to keep at least 1 of them, but this is clearly not a long term viable solution. In the end I want to get our central IT group to take over our backups if possible (we are a bit of an island outside of central IT), but as I pursue that path I also want to pursue a 2ndary path assuming they will say no. I am familiar with BackupPC and will look at the other recommendations above. I think that Bacula and Amanda are sort of the drop-in replacements for what we have now so I'll look at them most closely. But if I do have to carry forward with our own backups I'd ideally like to get out of the tape game - never liked tapes. Anyway, since the last big backup discussion was over a year ago I figured I'd kick off another one to see if anything new has come up in the mean time.

(f) is packaged in EPEL It does have its own quirks, of course. The main ones being that its rsync-in-perl (on the server side so it can work with its own compressed files while chatting with a stock remote rsync) is somewhat slow, and that its archive storage that uses hardlinks for pooling may end up being impractical to copy with file-oriented tools.

You can delegate target machines to 'owners' who can only see their own machines with their login to the web interface, but there is not an easy way to do it at the home directory or file owner level for a multi-user machine. You can make a 'host' which is a subset of a target, and point several of those at the same real host with the ClientNameAlias option but it would take some additional work to secure those against each other.

Re: [CentOS] UC /etc/cron.d
It's a good idea NOT to put stuff in /etc/crontab and NOT to change the existing members of /etc/cron.d. It is a good idea NOT to change root's crontab. Any of these may get overwritten by maintenance. We generally put cron stuff in a locally named and created member in /etc/cron.d.

Re: [CentOS] ZFS magic (was: Backup Redux)
Vreme: 12/08/2011 08:31 PM, Alan McKay piše: My non-tape solution of choice is definitely rsync = box with ZFS, snapshot however often you'd like. = forever incrementals. For more redundancy and performance, add more ZFS boxes, do replication between them. Not sure whether ZFS now makes this OT - if so, sorry for not putting OT: in the subject. Anyway, I have a ZFS storage unit here and this is my first exposure to it so I don't really know about any of this ZFS magic that I often hear about. I'm sure I could google and find some reading on the matter but am wondering if anyone has some recommended reading that is concise and to the point, and will give me a good intro.

Aside from the weirdness of using the --no-remote option to specify that in fact you do want a remote display, I can verify that I see the same thing. It looks like firefox-3.6.18-1.el5.centos does the same, so it is not a recent change. However, when I want to run GUI programs remotely I find it much, much nicer to have freenx running on the server and connect via the nomachine NX client amd take the whole desktop.

What I mean is merely incremental zfs send -i | zfs receive -F between two boxes for each new snapshot being created. You're free to mount the filesystem, but each new receive will roll it back to the previous snapshot when another incremental comes in (using zfs receive -F). It's not filesystem replication per se, but more periodic snapshots + incremental transfers.
