eoan verified. So, eoan is tougher. I installed it with subiquity and tried to follow the steps, but failed to convert to raid1, apparently, subiquity created the LV 1 PE larger than before or something, so it needed 1 free PE in the original PV to be able to add the raid1 metadata, which it did not have.
Worked around this by extending the PV size after the install (after tryin to shrink the existing LV first, messing up the install, and reinstalling ...). With proposed lvm2 ubuntu6.1 it boots as wanted, downgrading to ubuntu6 in release breaks it again. ** Tags removed: verification-needed verification-needed-eoan ** Tags added: verification-done verification-done-eoan -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1509717 Title: Wily LVM-RAID1 – md: personality for level 1 is not loaded Status in linux package in Ubuntu: Invalid Status in lvm2 package in Ubuntu: Fix Released Status in linux source package in Bionic: Invalid Status in lvm2 source package in Bionic: Fix Committed Status in linux source package in Cosmic: Invalid Status in lvm2 source package in Cosmic: Won't Fix Status in linux source package in Disco: Invalid Status in lvm2 source package in Disco: Won't Fix Status in linux source package in Eoan: Invalid Status in lvm2 source package in Eoan: Fix Committed Status in lvm2 package in Debian: Incomplete Bug description: [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 mdadm 7. Upgrade to lvm2 from proposed Reboot and check that it still boots. 8. Downgrade lvm2 to release Reboot and check that it fails to boot [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.
