Gp: installing alpine on LVM+GPT

installing alpine on LVM+GPT

New page

[[Category:Storage]]
This document describes how to set up a system booting from a logical volume in Alpine using lvm2 and GPT-labeled disks.

Begin by booting from Alpine installation media in the usual way. Log in as `root`, run `setup-alpine`, and answer `none` when asked to choose a disk.

=== Partitioning ===
We need to install some tools:
{{Cmd|apk add parted lvm2}}

Now we can create the partition table:
{{Cmd|parted -a optimal /dev/sda}}

unit MiB
mkpart 1 1 256
name 1 boot
set 1 legacy_boot on
mkpart 2 256 100%
set 2 lvm on

Now, exit `parted` and reboot to force a reread of the partition table (for some reason `partprobe` doesn't work here).

=== LVM Creation ===
Once you've rebooted, run through `setup-alpine` again.

Install some more necessary bits:
{{Cmd|apk add lvm2 e2fsprogs syslinux}}

Create a PV, VG, and a LV for the root partition:
{{Cmd|pvcreate /dev/sda2}}
{{Cmd|vgcreate vg0 /dev/sda2}}
{{Cmd|lvgcreate -n myhost.root -L 8G vg0}}
{{Cmd|rc-update add lvm}}
{{Cmd|vgchange -ay}}

Create file systems:
{{Cmd|mkfs.ext3 /dev/sda1}}
{{Cmd|mkfs.ext4 /dev/vg0/myhost.root}}

Mount the file systems in position:
{{Cmd|mount -t ext4 /dev/vg0/myhost.root /target}}
{{Cmd|mkdir /target/boot}}
{{Cmd|mount -t ext3 /dev/sda1 /target/boot}}

Now you can run `setup-disk` to install Alpine:
{{Cmd|setup-disk -m sys /target}}

Finally, install `syslinux` (note that we are installing to `/dev/sda`, *not* `/dev/sda1`):
{{Cmd|dd bs=440 conv=notrunc count=1 if=/usr/share/syslinux/gptmbr.bin of=/dev/sda}}

Reboot and enjoy your new Alpine installation!
