This is happening to me on an Intel NUC 5i5MYHE blade on PXE. The error is an iSCSI destination error apparently. Same scenario... Maas version: MAAS Version 2.1.3+bzr5573-0ubuntu1 (16.04.1) On node PXE boot console output (sorry, but some of this is cut off on this screen, typing what I can see. will switch to another monitor and reproduce if this is not enough of the error): lvmetad is not active yet, using sysinit disk/by-path/ip-192.168.199.2:3260-iscsi-iqn.2004-05.com.ubuntu:maas:ephemeral... ...ubuntu-amd64-generic-xenial-daily-lun-1" tgtd on the MaaS node seems to be running fine but netstat output does not show the initiator contacting it when I search for the IP that MaaS assigned on PXE init. tgtd MaaS node is Raspberry Pi 3B, so not a Dell issue specifically: root@juju-rack2:~# cat /etc/issue Ubuntu 16.04.1 LTS \n \l root@juju-rack2:~# uname -r 4.4.43-v7+ MAAS Version 2.1.3+bzr5573-0ubuntu1 (16.04.1) Intel blade is also running PCIe solid state drive, not a USB device.
