IIUC this would mean that you skip David's "pvs_online" file generation entirely. How did the auto-activation happen, then? > ``` > > the output of "systemd-analysis blame | head -n 10": > ``` > 59.279s systemd-udev-settle.service > 39.979s dracut-initqueue.service > 1.676s lvm2-activation-net.service Could it be that lvm2-activation-net.service activated the VGs? I can imagine that that would be efficient, because when this service runs late in the boot process, I'd expect all PVs to be online, so everything can be activated in a single big swoop. Unfortunately, this wouldn't work in general, as it would be too late for booting from LVM volumes. However I thought all lvm2-acticvation... services were gone with LVM 2.03?
