** Description changed: [Impact] system does not boot after converting lvm volume to raid1 w/o having mdadm installed. [Test case] 1. Install server with subiquity to LVM 2. Add second disk to it 3. Run pvcreate /dev/vdb 4. Run vgextend ubuntu-vg /dev/vdb 5. Run lvconvert -m1 --type raid1 ubuntu-vg/lv Reboot and check that it still boots. - 6. Remove demsetup + 6. Remove mdadm Reboot and check that it fails to boot 7. Upgrade to lvm2 from proposed Reboot and check that it still boots. [Regression potential] Not really anything, we just add the raid1 module to initramfs, so it might be loaded during boot, and raid1 logical volumes might appear earlier. [Original bug report] After upgrading to Wily, raid1 LVs don't activate during the initrd phase. Since the root LV is also RAID1-mirrored, the system doesn't boot. I get the following message each time LVM tries to activate a raid1 LV: md: personality for level 1 is not loaded! Everything was fine with Vivid. I had to downgrade to Vivid kernel (3.19.0-30) to get my system to a usable state. I pretty much hope it to be a temporary workaround and I'll get the new 4.2.0 kernel work with Wily in days.
