similar to: Feasibility of iscsi storage pool

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

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'>

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

Hi, John, and thank you! This was a very thorough and welcome response, I was wondering where all the storage guys were... I will get back to you with more details later, specifically about multipath, since this needs to be investigated thoroughly. I have, with trial and error method, during the elapsed time, been able to attach the NPIV pool LUN to a virtio-scsi controller, and it seems it

-----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.

Hi, I'm starting to experiment with iscsi based volumes and while this works fine so far I ran into a problem. When I add a LUN to a target and refresh tgtd all i/o to that target seems to hang for five seconds. This is obviously less than ideal if the plan is to use the target for lots of guests. There is also the possibility to create one target with one LUN for each guest disk but that

This is pretty epic if true. I'm installing some Fail 2008r2 now to check. Is your hypervisor running CentOS 6 or 7? -- Sent from the Delta quadrant using Borg technology!

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

Hello everyone, I have recently installed libvirt 1.0.0 and am having a problem with my iSCSI storage pool's autostarting. They are just going to an inactive state right after a reboot of the host. However once the startup is complete I can manually start the pool without problem. I am getting the following errors in the libvirtd.log file but they don't really give me much as to what

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

Hi again! Need to add here, since I been investigating a bit further, that it seems to be possible to add an NPIV vhba to the guest, using vdsm hooks. I've seen the reference to "host device assignments", which Dan pointed me too, but I didn't really understand the meaning of it at that moment. It would be interesting to hear from someone that have been doing it, how it would

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

Hello all, I am attempting to use the 'virsh attach-device' command to add storage to a guest from a pre-defined iSCSI-based storage pool. My desire is to attach a volume from the storage pool and have the storage pool recognize that the volume is in use and either flag it as such, or remove it from the pool so that subsequent queries to the pool will only return available storage
