An OS installer can create system.devices for the system and disks, but an OS image cannot create the system-specific system.devices. The OS image can instead configure the image so that lvm will create system.devices on first boot. Image preparation steps to enable auto creation of system.devices: - create empty file /etc/lvm/devices/auto-import-rootvg - remove any existing /etc/lvm/devices/system.devices - enable lvm-devices-import.path - enable lvm-devices-import.service On first boot of the prepared image: - udev triggers vgchange -aay --autoactivation event <rootvg> - vgchange activates LVs in the root VG - vgchange finds the file /etc/lvm/devices/auto-import-rootvg, and no /etc/lvm/devices/system.devices, so it creates /run/lvm/lvm-devices-import - lvm-devices-import.path is run when /run/lvm/lvm-devices-import appears, and triggers lvm-devices-import.service - lvm-devices-import.service runs vgimportdevices --rootvg --auto - vgimportdevices finds /etc/lvm/devices/auto-import-rootvg, and no system.devices, so it creates system.devices containing PVs in the root VG, and removes /etc/lvm/devices/auto-import-rootvg and /run/lvm/lvm-devices-import Run directly, vgimportdevices --rootvg (without --auto), will create a new system.devices for the root VG, or will add devices for the root VG to an existing system.devices. |
