Opinion on best way to use network storage
...se the image off the NFS mount. This has the benefit of all images being visible to all hosts (on the NFS mount), but I''m not sure about the performance. 2) Create an image on the SAN server for each XEN host and export it to the XEN servers through iSCSI. The XEN server will see it as a VolumeGroup. Create Logical Volumes in the VolumeGroup for each XEN guest. Has the advantage of using LVM for the guest instead of an image file (which is rumored to be faster). Disadvantage is individual images are not easily moved to other hosts 3) Create a image on the SAN server for each XEN guest and e...

Migrating DomUs from file VBD to LVM Backend
Hello, what would be the easiest and fastest way to migrate a file based DomU to a LVM based DomU. Given that the file contains a partition table + partitions. I tried with an dummy approach: dd if=/path/to/file.img of=/dev/volumegroup/logical-volume. That gives me a logical volume that xm create refuses to use....

"Can't find root device" with lvm root after moving drive on CentOS 6.3
...e anything. Further Googling got me the rdshell kernel parameter, and that dropped me to a shell when it failed to find the root device. Reading https://fedoraproject.org/wiki/How_to_debug_Dracut_problems , I did the following: # lvm vgscan # lvm vgchange -ay And then # ln -s /dev/mapper/<volumegroup>-<root_volume> /dev/root # exit After this, the box boots up normally, and everything works as it should. However, when I reboot, it again fails to find the root device. So, after all this, my question is, how do I make Dracut (I'm assuming) understand that this LVM volume is my ro...

libvirt and shared storage SAN Fiber Channel
...e LUN per VM). For each LUN we create an LVM VolGroup. On each VolGroup we create Logical volumes (one for swap, one for root filesystem). We present to the vm the 2 Logical Volume as it was raw disk. In this system we can make live migration between host using local scripts which assume than one VolumeGroup is used only by one host at the same time on the 8 node "cluster". We don't use any clustered aware environment like CLVM. We plan to migrate to kvm and libvirt with the new centos release (CentOS 6). Reading the upstream documentation and libvirt i don't find anything about...

LiveCD System recovery - Mounting LVM?
Hi, I am trying to recover data from my old system which had LVM. The disk had two partitions - /dev/sda1 (boot, Linux) and /dev/sda2 (Linux LVM). I had taken a backup of both partitions using dd. Now I am booting of CentOS live cd for system restore. I recreated partitions like previous system using fdisk and then used dd to dump all the data onto it. I would like to mount sda2 as LVM, but I

ext4 or XFS
Hi all, I've a 30TB hardware based RAID array. Wondering what you all thought of using ext4 over XFS. I've been a big XFS fan for years as I'm an Irix transplant but would like your opinions. This 30TB drive will be an NFS exported asset for my users housing home dirs and other frequently accessed files. - aurf

iSCSI storage pool questions
Hi All, I've been trying to figure out the best way of using an iSCSI SAN with KVM and thanks to a helpful post by Tom Georgoulias that I found on this list (https://www.redhat.com/archives/libvirt-users/2010-May/msg00008.html), it appears I have a solution. What I'm wondering is the following: 1) If I use an iSCSI LUN as the storage pool (instead of creating an LVM VG from this iSCSI

converting system to raid1
Hello, I've got a single-drive CentOS5 system with two partitions on it, a 101 mb boot, and the rest of the disk as an lvm volume, two partitions in it, / and swap. I've got another disk, same size, and i'd like to add it in as a primary slave drive and convert this system to raid1 for redundancy. I do not want to reinstall this box, which is what the docs i've read say

replace x86 with x64 system and reuse existing LVM
I want to replace an existing 32bit with a 64bit installation (Centos 5). There's an existing LVM with lots of partitions. Most are used for Xen guests. The system itself uses only one of them plus a separate /boot partition that is not on LVM. What's the best course of action here? Should I do the reinstall with kickstart or better manually and reuse the existing filesystem? As I
