I'm on "Ubuntu 19.04" (disco), with initramfs-rools at version 0.131ubuntu19, and this is still broken for me.
lvdisplay gives /dev/xubuntu-vg/swap_1 as the swap logical volume path and dzVm4y-Xeh5-o9UB-jLnI-0ldX-azSN-9w6QZq as the UUIS. I've tried separately with /etc/initramfs-tools/conf.d/resume as RESUME=UUID=dzVm4y-Xeh5-o9UB-jLnI-0ldX-azSN-9w6QZq and RESUME=/dev/xubuntu-vg/swap_1 and RESUME=none each time running sudo update-initramfs after updating the resume file. But, I always get a 30 second delay and the following in boot.log at the following boot: WARNING: Failed to connect to lvmetad. Falling back to device scanning. Volume group "xubuntu-vg" not found Cannot process volume group xubuntu-vg WARNING: Failed to connect to lvmetad. Falling back to device scanning. Reading all physical volumes.

Falling back to device scanning. Status in initramfs-tools package in Ubuntu: Fix Released Status in ubiquity package in Ubuntu: Fix Released Status in initramfs-tools source package in Bionic: Fix Released Status in ubiquity source package in Bionic: Fix Released Bug description: [SRU Justification] A regression in initramfs-tools causes it to autogenerate config in the initramfs saying to resume from any available swap devices, but references the swap device by UUID, which is not a canonical form for referring to LVM volumes (because of snapshotting, they are not unique). Ubiquity also generates a file in /etc at install time which references the swap partition in the same way. Since the lvm2 initramfs hooks also only activate precisely those LVs that are detected as needed at boot, this adds an inappropriate 30-second boot delay to any system with swap on LVM, which includes any desktop system that was configured with LVM (but not full-disk encryption) at install time. [Test case] 1. Install using the "Use LVM" option in the desktop installer. 4. Reboot. 5. Verify that dmesg shows a 30-second delay before mounting the root filesystem. 6. Install initramfs-tools from bionic-proposed. 7. Reboot. 8. Verify that dmesg no longer shows a 30-second delay before mounting the root filesystem. 9. Install using the bionic daily image that contains the ubiquity from bionic-proposed. 10. Reboot. 11. Verify that /etc/initramfs-tools/conf.d/resume is not present and that there is no delay before mounting the root filesystem. [Regression potential] This makes changes to shell scripts, and shell is a perilous language. An unnoticed bug could cause all initramfs generation, and thus all kernel installation, to fail for some users. A regression could also cause a user to lose hiberation support that they currently have. [Original description] After choosing "Erase disk and install ubuntu" + "Use LVM with the new Ubuntu installation", the system is very slow to reboot. It shows the message : "WARNING:Failed to connect to lvmetad. Falling back to device scanning.", then waits 32 seconds, then continues as it should. I think this is a ubiquity bug, since the d-i based installer is not affected. - ubuntu-18.04-desktop-amd64.iso (a55353d837cbf7bc006cf49eeff05ae5044e757498e30643a9199b9a25bc9a34) : affected - xubuntu-18.04-desktop-amd64.iso (7c24318d3b1de1efd584b5aea034ce1aafd2d0f06c59812d989a5fc95bf947e3) : affected - ubuntu-18.04-server-amd64.iso (a7f5c7b0cdd0e9560d78f1e47660e066353bb8a79eb78d1fc3f4ea62a07e6cbc) : not affected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1768230/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
