Resizing disks for VMs
Hi, Is there a way to make a PV xen guest aware of a size change of the host disk? In my case I'm talking about a Centos 5.3 host using logical volumes as storage for the guests and the guests running Centos 5.3 and LVM too. What I'm trying to accomplish is to resize the logical volume for the guest by adding a few gigs and then make the guest see this change without requiring a

Experience with Centos running off usb-stick(s)
Hi, I'm trying to build a redundant duo of firewalls/routers/gateways and I'm thinking about not putting any disks in them and instead using a usb-stick raid-1 as storage. Has anyone any experience with this? Since the machines will be running pretty much only iptables, conntrackd and keepalived there is not going to be a lot of disk activity going on and the plan is to do all the

Any alternatives for the horrible reposync
Hi, I'm currently trying to mirror a couple of yum repositories and the only tool that seems to be available for this is reposync. Unfortunately reposync for some inexplicable reason seems to use the yum config of the local system as a basis for its work which makes no sense and creates all kinds of problems where cache directories and metadata gets mixed up. Are there any alternatives? Some

VLAN issue
Do you need the whole configuration? On the switch end, we have the relevant VLAN (VLAN 48) with the assigned IP address of 192.168.48.101 and the range of ports (Gi1/0/1 - Gi1/0/8) assigned to that VLAN. Seems - and acts - like a legitimate setup and works fine, except for this particular instance. Thanks. Boris. On Fri, Jan 23, 2015 at 8:54 PM, Dennis Jacobfeuerborn < dennisml at

win2008r2 update on centos 6 host made system unbootable
Hi, today we ran into a strange problem: When performing a regular Windows 2008r2 update apparently among other things the following was installed: "SUSE - Storage Controller - SUSE Block Driver for Windows" Previously the disk drive was using the Red Hat virtio drivers which worked just fine but after the reboot after the update I just get a blue screen indicating that Windows cannot

VLAN issue
Andrew and Dennis are spot on. Their conclusions about your server being connected to an access port and not a trunk port would be my conclusion as well.

cgroups not working?

I modified cgconfig.conf like this: group webserver { cpu { cpu.shares="250"; } } and addes this to cgrules.conf: *:httpd * webserver Looking into the "webserver" cgroup shows that the pid's of

Xen vs. KVM console
Hi, I'm trying to get the console support in KVM working as well as on Xen but right now I'm stuck. I followed these instructions: http://prefetch.net/blog/index.php/2009/06/17/redirecting-the-centos-and-fedora-linux-console-to-a-serial-port-virsh-console-edition/ This works out fairly well except that I cannot watch the bootup of the machine in the vnc console anymore only on the

Storage performance
Hi, I recently did some benchmarking on a Rackspace VM and was surprised that bonnie++ showed a read throughput of almost 500MB/sec. Does anyone have an idea how they achieve these speeds in a shared environment? While you can achieve this with a RAID easily these days once you have lots of VMs accessing that array I would expect that speed to go down quite a bit. Was I just lucky that I was

onboot=yes not working for eth0.x:y interfaces?
Hi, I ran into a Problem when using alias interfaces with vlans on a centos 5 box. When I define such an interface and do a "service network restart" the alias interface doesn't get started. Starting it manually works fine. Also after changing DEVICE=eth0.10:0 to DEVICE=eth0:0 in the config file the interface is started after a network restart. Does anyone have an idea what the

transparent_huge_pages problem (again?)

I'm posting here because this issue cam up in the past: http://bugs.centos.org/view.php?id=5716 That bug was closed with "resolved in EL6.4" but now it seems to have returned. Apparently there

Update to 1503 release problem
Hi there, Yesterday I've updated from 7 to 7.1 and today I've noticed on 2 server that postgresql systemd file was replaced with default values. This make postgres to no start and webserver give me problem. This problem was fixed and now all works good. It's normal that on major update I can get this problem? If so, I've ridden release change but I have not ridden about
