Setup multiple bridges for use with KVM
by Jacob Hydeman 13 Jan '10

13 Jan '10

Running CentOS 5.4 x64. Have successfully bridged eth2 with br2 by following the instructions here: http://wiki.libvirt.org/page/Networking (under the RHEL section) Have been running several KVM VMs successfully via this bridge. I am now trying to bridge additional interfaces by using the same routine. Each bridge is named to correspond with the ethX device its bridged with. Example of ifcfg-eth0 script: DEVICE=eth0 HWADDR=00:16:76:D6:C9:45 ONBOOT=yes BRIDGE=br0 then of ifcfg-br0 script: DEVICE=br0 TYPE=Bridge BOOTPROTO=dhcp ONBOOT=yes DELAY=0 This is repeated 3 times for eth0-eth2 and br0-br2. I've read somewhere that STP needs to be enabled when using multiple bridges. I've tried adding STP=on to the ifcfg-brX scripts but with the same result. Yes, brctl shows that STP is on. The original bridge eth2-br2 continues to work but I can't get any traffic across any other bridge. Either by dhcp or static ips. Is multiple bridges a possibility? Previous to moving to KVM I was running Xen Server on the same hardware. I am just trying to recreate the network setup I had. I believe Xen Server runs on top of a linux platform so such a thing should be possible. Thanks, Jacob

mapping sar -d devices to mount points
by Blackburn, Marvin 13 Jan '10

13 Jan '10

Sar -d reports devices like dev253-0. How can I map these to a mount point? I use a mixture of lvm with ext3 filesytems, plain ext3 filesystems on local storage, and ext3 filesystems on powerpath devices. Any help would be appreciated. _____________________________________ "He's no failure. He's not dead yet." William Lloyd George

Using them some thing like this: --delete --backup --backup-dir=$MIRROR_DIR/RsyncBckups --suffix=".$DATE" allows you to keep an exact duplication of the original directory and keeping the original files that were either deleted or overwritten in a seperate backup directory with dated suffixes, which can be archived on some regular basis. This should allow you to keep the simplicity of rsync and control the cumulative size. Brett

Backuppc is good for this - it can use rsync for the transfers (or tar or smb) but all duplicate data is compressed and pooled even if found on different machines and it has an easy setup to control how long old copies are retained. -- Les Mikesell lesmikesell(a)gmail.com

kickstart %pre help on C5.4
by Alan McKay 13 Jan '10

13 Jan '10

Hey folks! I'm doing some %pre work for the first time in a very long time, and have been at this all day so far and still don't have anything sorted out properly. First I tried just doing some simple bash stuff like this %pre #!/bin/bash # stuff I reduced "stuff" down to basically a simple "select" statement to echo and read input, just for the sake of debugging. My first problem is that when running the kickstart, the little box would come up saying it is running the pre scripts, but my scripts would never actually run. No output, no prompts, nothing. So after some muddling I tried this : %pre #!/bin/bash exec 1>&3 exec > /dev/tty chvt 3 exec < /dev/tty3 > /dev/tty3 clear # stuff I cannot say I really understand this - it is just something I came across. in any case, now my script seems to run fine, but after it finishes it does not appear to go back to my install. I get messages like : date INFO all kickstart %%pre script(s) have been run date WARNING resolution and depth not specified, try to be sane and that is it - it stops there. I've also tried just : %pre #!/bin/bash chvt 3 clear # stuff With the same results as above. This is all running within VMWare ESXi 4.0 if that matters. What am I missing here? thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"

Backup server
by Sorin Srbu 13 Jan '10

13 Jan '10

Hi all, I've built a new backup server for our linux-clients. Is Amanda the way to go for a backup-solution? It seems to be pretty powerful, if a bit finickety to set up initially. The way we currently do backups is to use rsync from the clients to two folders on an older server that rolls over every other week. This worked fine for a while, but the rsync is cumulative and the users generate a tremendous amount of data every day after having had a client upgrade with newer and hilariously fast computers for calculation. The previous *nix-admin set it up this way with rsync, meaning that we in the long run have data that is way obsolete and get increasingly difficult to maintain. As the backup solution must be next to free, ie "free beer", Amanda looks suitable.
