similar to: Selecting raw logical volumes during guest VM creation

Greetings - I am hoping someone can confirm for me the steps that I am using to add an LV to an existing Guest in KVM, and what I am seeing as I do some of these steps. My host (earth) is CentOS 6 and so is my guest (disect). The guest (disect) is my testing server. The main objective of what I am trying to do is add a logical volume for /var into my guest. The LV (lv_disectvar) is part

Greetings - Ok, I made a mistake that I need to fix. Fortunately it is not a destructive mistake, but I need some advice on how to correct the problem. CentOS 6.3 host system named Earth I was creating some new logical volumes within my exiting volume group for a new virtual machine using the LVM GUI. When I created the LV that I plan to use for root partition of the new VM (Bacteria) I

Greetings - I shutdown one of my Centos 6.2 VMs for some offline maintenance and am now unable to get it to restart. I am also unable to create and start a new VM. The host system is Centos 6.2, fully up to date. I have been searching Google for two days and have not been successful in getting a VM to start. I have restarted libvirtd, but did not want to shutdown my other two running VMs and

Hi All, I'm having issue with creating LVM volume via libvirt. XML of LVM StoragePool is:     VG01             /dev/VG01       (existing vg) XML of create volume in lvm pool is:     ub_test01.img     0     1                 When I create the volume with above XML defn, lvs command to list logical volume shows a value in the origin column indicating it was created as snapshot.. the

Greetings - I have not been a long time follower of this list, but I have scanned through the last year or so of archives, after not finding much from google searches. I am hoping someone here can inform me if what I want to do is feasible, and give me some general guidance to follow so that I can continue my research and complete this task. I admin a RH3 system that is primarily a Samba

Greetings - I have searched the mailing list archives and my Samba 3 book and have not seen this issue addressed anywhere. My home desktop box has Win98 installed on a 20 GB drive and Centos 4.4 on a 160 GB drive with a Grub menu for selecting which OS to boot. I am wondering if it is theoretically possible to share (read and write) files on the Linux drive when booted to Window, and vice

Greetings - I am trying to install CentOS 7 into a new Dell Precision 3610. I have two 3 TB drives that I want to setup in software RAID1. I followed the guide here for my install as it looked fairly detailed and complete (http://www.ictdude.com/howto/install-centos-7-software-raid-lvm/). I only changed the size of the partitions from what is described, but ended up with the disk

i'm trying to setup LVS, and tried both the lvs-dr and the lvs-nat, but can't get any to work. I'm hoping people here can answer a few questions that might help and shed light onto the situation? #1 with regards to the Real Servers, is there anything that needs to be configured other that the http service? I ask this, because I suspect yes, and it has to do with what type of LVS you

I still get the "the discard operation is not supported" fstrim error when the LVs are set to "nopassdown" Seems that when I use ext4 the fstrim reports that it worked but the LVs Data% does not decrease after the fstrim. xfs just throws the error. I've also been looking at the output of lsblk -D # lsblk -D NAME DISC-ALN DISC-GRAN DISC-MAX DISC-ZERO xvdb

Hi guys, I''m not sure where to post for help on this one, shorewall or lvs, I''ll start with shorewall (only cause Tom is a gun at this stuff, and is polite enough to tell me to bugger off to the LVS list if I''m posting in the wrong one ;) I have a single box that is my router/firewall/LVS. Internet -- eth0 - router/firewall - eth1 --- internal lan | eth2

lvm2 2.02.107 adds the -S/--select option used in lvs to filter out only public LVs (see RHBZ#1278878). To make this work again with versions of lvm2 older than that, only on old versions filter out thin layouts and compose the resulting device strings ourselves. The filtering done is much simplier than what "-S lv_role=public" will do, but should be good enough for our need. ---

We are building an exchange cluster with two front end Outlook Web Access servers. We would like to at least have some sort of failover, and prefereably load balancing for them. The MS recommended way is to use NLB, but for various reasons that's not working with our set up. We are looking to set up a single linux server and use something like LVS to load balance/fail over the

Hello! I have set-up four nodes system: two LVS load balancers (CentOS) and two working nodes (openSUSE). LVS nodes have global IPs, so they able to access the internet and working nodes have only private IPs, so they cannot access internet directly. I use NAT-base load balancing. Now I need to know how give working nodes ability to access the internet? I ask this because I don't know how to

Hi All, I'm having issue with creating LVM Volume via libvirt. We are running libvirtd 1.2 with KVM. We are creating Volume Group (VG01) outside of libvirt and defining a storage pool for it. Here is the StoragePool XML for the Volume Group created outside libvirt. <pool type="logical"> <name>VG01</name> <target>

Greetings - I am preparing to order a new desktop system for work. In general the new system will be a Dell Precision T3610 with two 3 TB drives. I plan on installing CentOS 7 as a KVM host, with virtual machines for Win 7 Pro and Linux Mint. I am looking for some advice or a good how-to on configuring software raid on the two drives, then using LVM for the host and virtual machines. I

Hi All I'm trying to setup my LVM thin pool to support discards so that the pool can reclaim space even if the underlying device doesn't support trim. It is my understanding that all thin pools should support trim even if the underlying device doesn't. (please correct me if I'm wrong here) I have one centos server that does support trim and everything is working correctly but any

As far as I can tell, this is because in the dracut boot process, the device backing VolGroup is activated, but the device backing BackupGroup is not.? As a
