** Description changed: Doing a clean install of ubuntu server 18.10 alt install, with gpt -> mdraid -> lvm -> btrfs. Installer completes successfully, grub-install completes successfully, but upon first boot I receive a grub "lvmid disk not found" error and thrown into the recovery console. I know this setup is complex and perhaps not ideal, that aside, I've had it work in the past without issues or modification after installer. - I have tried the follow, all resulting in the same lvmid not found error in grub: + I have tried the following, all resulting in the same lvmid not found error in grub: - making a separate /boot LV with ext4 instead of btrfs + - setting root=UUID=xxx in /etc/default grub - preloading lvm/mdraid modules in /etc/default/grub + - not using btrfs subvolumes in root (although should be an issue as ubuntu creates them by default) - using raid5 only (not mixing raid1/5 for PV) - - setting root=UUID=xxx in /etc/default grub + - running update-initramfs from chroot Also, a little background as to why I'm doing the partitions/raid/lvm as I am can be found here: https://serverfault.com/questions/272776/how-to- do-the-equivalent-of-synology-hybrid-raid-on-linux-myself Setup is as follows: === /ets/fstab /dev/mapper/vg1-root / btrfs noatime,subvol=@ 0 1 /dev/mapper/vg1-root /home btrfs noatime,subvol=@home 0 2 /dev/mapper/vg1-swap none swap sw 0 0 === blkid /dev/sda1: PARTUUID="32e4d29c-844f-4793-8eca-f5656432ead5" /dev/sda2: UUID="ad79a45d-4609-b2f3-b2d2-e97802031740" UUID_SUB="806397cd-bb32-3e05-ad3a-6888c075f326" LABEL="jarvis:0" TYPE="linux_raid_member" PARTUUID="22b13abe-db68-4bc3-b1b3-ce1786bbee4d" /dev/sda3: UUID="649390e4-1cae-f25c-0792-89590d5f1853" UUID_SUB="de6a5629-6dc2-3f02-f826-9dc830897997" LABEL="jarvis:1" TYPE="linux_raid_member" PARTUUID="dd2048a5-ea24-4d9e-a5cf-d66dc808cebc" /dev/sda4: UUID="b6863d97-ea04-ab1c-b0d5-aa2d44eed9b1" UUID_SUB="c9c3072b-3d6e-8b6e-3079-770f2d0be910" LABEL="jarvis:2" TYPE="linux_raid_member" PARTUUID="f040a326-c446-4330-ba79-5c42d7aee6f2" /dev/sdc1: PARTUUID="2c8cd1b1-d237-4bb4-940d-496634fc16a7" /dev/sdc2: UUID="ad79a45d-4609-b2f3-b2d2-e97802031740" UUID_SUB="39df4b32-dd92-754c-ecf2-9bccb1985fe1" LABEL="jarvis:0" TYPE="linux_raid_member" PARTUUID="291de3df-58be-4054-ab90-e65af7d9ae03" /dev/sdc3: UUID="649390e4-1cae-f25c-0792-89590d5f1853" UUID_SUB="4bcf6186-4284-3254-503f-9a937ccc1a70" LABEL="jarvis:1" TYPE="linux_raid_member" PARTUUID="cdf51368-faf0-4455-a286-8ab3330d720e" /dev/sdc4: UUID="b6863d97-ea04-ab1c-b0d5-aa2d44eed9b1" UUID_SUB="a7e1157a-69d1-708f-b28b-b01ec43f5de7" LABEL="jarvis:2" TYPE="linux_raid_member" PARTUUID="1eff3990-5a32-4c9e-a622-b410f2285b51" /dev/sdd1: PARTUUID="7c247a87-1177-4da6-b52b-612fdc7df0b2" /dev/sdd2: UUID="649390e4-1cae-f25c-0792-89590d5f1853" UUID_SUB="3bd9c6a8-54d9-5fbe-509b-885c5655cf9c" LABEL="jarvis:1" TYPE="linux_raid_member" PARTUUID="9c61a3d2-ecb7-4f80-87b6-f590183ab898" /dev/sde1: PARTUUID="3a3342c7-366f-41ef-b3d3-0d0c3a349014" /dev/sde2: UUID="ad79a45d-4609-b2f3-b2d2-e97802031740" UUID_SUB="f2441bfc-7a4a-0595-43f9-bfb0695ba35a" LABEL="jarvis:0" TYPE="linux_raid_member" PARTUUID="8ae879b1-b880-428c-9967-14615346382f" /dev/md127: UUID="H10Yrl-SAkb-0bAE-OYpG-pBhQ-iz0U-dKq427" TYPE="LVM2_member" /dev/md126: UUID="Sm53JC-Iz2u-eAf9-NYbb-GFYI-7DKh-al5p6v" TYPE="LVM2_member" /dev/md125: UUID="vhvdNY-Mvgv-QM7s-EcD7-Wzr9-I1D4-abcZ9z" TYPE="LVM2_member" /dev/mapper/vg1-swap: UUID="91c45d4d-6f9e-49ab-8a6d-476f18afa133" TYPE="swap" /dev/mapper/vg1-root: LABEL="root" UUID="aa02e081-d12c-4b5e-9dbd-8613ba77ce26" UUID_SUB="55f643de-4203-41d5-b042-f765e57744f0" TYPE="btrfs" === lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT + loop0 7:0 0 819.5M 1 loop sda 8:0 0 3.7T 0 disk -
