[Test case] 1) Install on multipath system using EMC XtremIO storage / OR: a) Start d-i install on qemu with multipath enabled b) exit to d-i menu c) modify /etc/multipath.conf to define path selector as 'queue-length' for the local qemu device. d) restart multipathd if necessary. 2) Try to complete the install, setting up storage as multipath and using the multipath device as boot disk. 3) Reboot to disk.

The multipath-modules.udeb (src:linux) does not include it in the installer, nor multipath-tools-boot (src:multipath-tools) installs it in the initramfs.

The hw-detect change is uploaded, so once it's in the archive, installs on hardware requiring dm-queue-length should work without issues. We're still blocked on having the kernel include dm-queue-length and dm- service-time for the installer for the hw-detect side of this SRU to yakkety and xenial.

This bug was fixed in the package multipath-tools - 0.6.4-3ubuntu2 --- multipath-tools (0.6.4-3ubuntu2) zesty; urgency=medium * debian/initramfs/hooks: - Remove old dm-emc module; it hasn't been in kernel since 2.6.27. - Add dm-queue-length: users may want to change from the default selector and should be able to do so. (LP: #1673350) * debian/patches/path_selector.patch, debian/patches/series: remove path_selector.patch to get back to the "right" default selector of service-time, which has been included in the kernel module packages for a while now and has better throughput than round-robin.
