I use mostly lvmDo you mean you want to use a iSCSI disk as the root device of your Dom0, or do you plan on using iSCSI as backends of your guests?

I want to export same iscsi to second server.This means you have a iSCSI target running on the Dom0, and plan to attach disks exported from this target to both the Dom0 and the guests?

Hi, "jacek burghardt" <jaceksburghardt@gmail.com> írta 2013-01-16 08:29-kor:> I setup new dell server and I have created iscsi. Is there how to on > using iscsi for boot drives under xen 4.2. I use mostly lvmI think what you are looking for, is some collection of best practices. Suggestions: * forget lvm -> use one lun for one disk, if you have too many disk, try to group your disks, and create several target * if U use some modern linux as dom0, than udev gave constant name to your iscsi disks, so your vm''s config could be look like this: disk=[''phy:/dev/disk/by-path/ip-10.10.1.1:3260-iscsi-iqn.1986-03.com.sun:02:test-lun-0,xvda,w'', ... ] * if you use multipath, than the whole constant naming could depend on your multipath.conf, so success story again * care about your service dependency, so your iscsi-initiator should start before your domUs (or with multipath: iscsi << multipath << domUs ) That''s all folks!
