similar to: iSCSI storage pool questions

I've configured a libvirt storage pool using an iscsi target from a Sun 7310 storage appliance and am using the LUNs in this target as volumes for my KVM guests. The setup is very similar to what Daniel covered in a recent blog posting: http://berrange.com/posts/2010/05/05/provisioning-kvm-virtual-machines-on-iscsi-the-hard-way-part-2-of-2/ It works great, but I can't figure out how

I need the community''s opinion on the best way to use my storage SAN to host xen images. The SAN itself is running iSCSI and NFS. My goal is to keep all my xen images on the SAN device, and to be able to easily move images from one host to another as needed while minimizing storage requirements and maximizing performance. What I see are my options: 1) Export a directory through NFS.

Hi, I'm looking information about using libvirt with san (fiber channel) based storage and googling for a while i don't see anything about it. I send this email in order to get advices about libvirt and shared storage We use here, for 3 years now, 8 linux centos server connected to an hitachi FC SAN (multipath devices). Each server run Xen dom0 and use SAN LUNs to store Virtual machine

Hi, I want to start using iscsi storage but ran into a problem. I defined a storage pool and this contains my first LUN which is mounted on a hypervisor. When I now add a second LUN on a target and do a tgt-admin --update --force to reload the target the i/o to the first LUN seems to freeze for a few seconds. Now I'm wondering if I'm doing anything wrong? It's not really tolerable

Hi, When I add a new LUN on an iscsi target and then issue a pool-refresh command on the respective storage pool in libvirt, libvirt will not find the new lun (or notice if luns have been removed). I'm using a Dell PowerVault MD3200i iSCSI Array to hold the volumes for virtual servers in libvirt. In libvirt, I have defined the storage pool as this: <pool type='iscsi'>

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Former user of Xen and newbie in kvm/qemu/libvirt stuff, I give it a try on my network ;-) I need to run a VM with iSCSI target attached. I did it this way : 1) Creation of iscsi pool (equa.xml) : <pool type="iscsi"> <name>equalog</name> <source> <host name="10.10.0.1"/> <device

Hi All, I'm running KVM host on CentOS 5.6 x64, all of my guests are CO 5.6 x64 as well. I create / run VMs via libvirt. Here are the packages I have: # rpm -qa | egrep "kvm|virt" kvm-83-224.el5.centos python-virtinst-0.400.3-11.el5 kvm-qemu-img-83-224.el5.centos kmod-kvm-83-224.el5.centos libvirt-python-0.8.2-15.el5 etherboot-zroms-kvm-5.4.4-13.el5.centos libvirt-0.8.2-15.el5

Hi, I finally managed to have one node working. I added a iSCSI LUN (ok if selinux is set to 0) and wanted to create my first VM. So I created a VM and had some issues: * I can choose boot from HD but I'm just able to choose the LUN, not a specific size in the LUN like you can do in vmware ESX. So, do I have to create a LUN per VM? If yes, it's quite complicated... * If I choose boot from

Hello everyone, My organization has an iSCSI LUN on a XenServer 6.0.2 host that is having issues. Last night we attempted a snapshot on a VM that is critical to our infrastructure. During the snapshot, the task locked up and was unable to progress or stop the snapshot. I attempted to force the VM to stop as well as destroy it''s domain. As a last resort I had powercycled the host. Upon

Hey everyone, Is anybody aware of a /true/ active/active multi-head and multi-target clustered iSCSI daemon? IE: Server 1: Hostname: host1.test.com IP Address: 10.0.0.1 Server 2: Hostname: host2.test.com IP Address: 10.0.0.2 Then they would utilize a CLVM disk between them, let's call that VG "disk" and then directly map each LUN (1,2,3,4,etc) to LV's named 1,2,3,4,... and

Hello, How to explain to fdisk that /dev/sda size changed? I increased LUN on storage, reloaded iscsi, did echo 1 > /sys/<something>/rescan. And I see in "dmesg" that kernel found new size of the LUN. But when I type "fdisk /dev/sda" it still shows old size. On /dev/sda1 sits LVM PV and I'd like to resize it instead of adding one more PV to volume group.

Hi, I've been trying a couple of day now, but I can't seem to figure it out. On www.etherboot.org, I found the example of configuring gPXE so that it mounts an iSCSI lun and then boot from CDROM so you are able to install on the LUN. But if I use gpxelinux.0 (latest release 3.73), with sanboot.c32 like this: label sanboot2008srv menu label ^[iscsi] Windows server 2008 kernel

Hi, I'm using libvirt 0.8.3 on Fedora 14 (as I wrote earlier, I'm having some trouble updating to the newest version), and I'm having problems getting iscsi and mpath storage pools to work in a usable and consistent manner. I have two storage pools defined on the host machine, one for raw iscsi- devices and one for those same iscsi devices device-mapped by multipath. They look

Hi, I try to define an iscsi pool with virsh but I always get the following error : error :internal error: missing backend for pool type 5 (iscsi) And yet libvirt was compiled with iscsi support : configure: Storage Drivers configure: configure: Dir: yes configure: FS: yes configure: NetFS: yes configure: LVM: yes configure: iSCSI: yes configure: SCSI: yes configure:

I am confused, because I would have expected a 1-to-1 mapping, if you create an iscsi target on some system, you would have to specify which LUN it connects to. But that is not the case... I read the man pages for sbdadm, stmfadm, itadm, and iscsiadm. I read some online examples, where you first "sbdadm create-lu" which gives you a GUID for a specific device in the system, and then

Hi Bootmeisters, I am using gpxelinux.0 + sanboot.c32 to boot a diskless machine into Linux. I would like to use device-mapper-multipath to provide fault tolerant access to its root disk. Although I am able to do this by hardcoding the additional paths in the initrd, it would be better if the bootloader could pass the information in the iBFT (iSCSI Boot Firmware Table). However, at the

Hello, I?m using ZFS to export some iscsi targets for the virtual box iscsi initiator. It works ok if I try to install the guest OS manually. However, I?d like to be able to import my already prepared guest os vdi images into the iscsi devices but I can?t figure out how to do it. Each time I tried, I cannot boot. It only works if I save the manually installed guest os and re-instate the same

Hi friends, i have a problem. I have a file server which initiates large volumes with iscsi initiator. Problem is, zfs side it shows non aviable space, but i am %100 sure there is at least, 5 TB space. Problem is, because zfs pool shows as 0 aviable all iscsi connection got lost and all sharing setup is gone and need restart to fix. all time till today i keep delete snapshots and make it alive

Hi all, Imagine the following situation, you have : - one ISCSI storage server providing : lun0 and lun1 - the lun0 and lun1 contains a standard installation of Fedora : VM1 and VM2 - the standards installations define two VG VolGroup00 ... We didn't define LogicalVolume on the node and we attached directly the iSCSI lun to the VM without making partition or LV in Ovirt. On the
