I've run into the same issue with a lucid guest running on XCP. Everything I can find says that the first block device *should* be xvda, but mine is sda, and that causes the open-iscsi to sysfs error.
Is there a way to force xen or this udev to move the block device out of the way? # udevadm info --query=all --name=/dev/sda P: /devices/vbd-51712/block/sda N: sda S: block/202:0 S: disk/by-path/xen-vbd-51712 E: UDEV_LOG=3 E: DEVPATH=/devices/vbd-51712/block/sda E: SUBSYSTEM=block E: DEVNAME=sda E: ID_PATH=xen-vbd-51712 E: ID_PART_TABLE_TYPE=dos E: MAJOR=202 E: MINOR=0 E: DEVTYPE=disk E: DEVLINKS=/dev/block/202:0 /dev/disk/by-path/xen-vbd-51712 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/672759 Title: open-iscsi duplicates exsiting block device on initiator login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/open-iscsi/+bug/672759/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
