My LVs in the only volume group I have are marked as "inactive" (vgscan) or "NOT available" (lvdisplay) respectively after machine restart.

vgchange -an makes them active / available, however needs to be called manually after every reboot.

My root filesystem or anything system/OS related is stored on MBR partitions, not involving LVM. Though it might be worth mentioning it's all -- OS related partitions and LVM-VG partition -- on the same physical device (/dev/sda).

This is a minimal Debian/buster system, freshly set up via debootstrap, very unlikely to involve config file changes applied manually. But potentially missing something due to not being installed via an ISO / disk image involving the installer.

Question: What's supposed to be the correct way of making LVs of certain and/or all VGs available at startup?

Answers I'm not satisfied with, yet being marked as accepted answers to quite a number of similar questions around here:

"Put vgchange -ay into /etc/rc.local (or wherever)."

This is mainly due to another system I maintain, also having its system/boot/OS related data on only MBR partitions (no LVM) involved, does boot with VGs/LVs being active (them, though, being on an externally attached USB drive). But also it feels like just mitigating the root cause of the issue.

Looking around I found:

  • /etc/init.d/lvm2 which looks like exactly doing the right thing: calling /sbin/lvm vgchange -aay --sysinit at boot. However the relevant part of the script never gets executed. Execution stops very early when sourcing /lib/lsb/init-functions. I assume this being a legacy SysV script which purposely gets ignored in favour of systemd service files.
  • /usr/share/initramfs-tools/scripts/local-top/lvm2 which gets executed during early boot as part of booting via initramfs. However here VG/LV activation only happens when the root filesystem is located on an LV, which in my case isn't the case, hence no activation here either.
