Hey, Guys:

While the discussion on Backdraft (http://backdrift.org/xen-block-iscsi-script-with-multipath-support) is very powerful it seems to focus exclusively on the use of multipath. I think that Jacek is asking whether to:

1. export the logical volumes (i.e., LV's) from his LVM volume group (VG) as individual iSCSI LUN's or to
2. export the underlying partitions and then import them to his host system as physical volumes (PV's) and then parition create the VG and the LV's on the host system.

Subject: [Xen-users] iscsi on xen

I wonder if someone can point me in right directions. I have two dell servers I setup iscsi  so I have four 2 tb hard drives and i had used lvm to create one big partiton and share it using iscsi. How I go about assigning sections of iscsi for virtual hard drives .  should go about assigning Should I export the whole 8TB as one iscsi and then use lvm to create smaller virtual disk. Or should I export smaller portions of lvm as separate iscsi. Right now I use lvm and this is my  disk = [ 'format=raw, vdev=xvda, access=rw, target=/dev/xen/win2012b. Do I need to install and use oopen-iscsi ?  Any pointers to documentation
