I've install a CentOS Stream 9 system from a kickstart file that specified (among other things) several logical volumes: logvol / --fstype="ext4" --size=10240 --name=lv_root --vgname=VolGroup logvol /var --fstype="ext4" --size=4096 --name=lv_var --vgname=VolGroup logvol swap --fstype="swap" --size=2048 --name=lv_swap --vgname=VolGroup When that system rebooted, the kernel args did specify "rd.lvm.lv=VolGroup/lv_root rd.lvm.lv=VolGroup/lv_swap", but did not specify "rd.lvm.lv=VolGroup/lv_var", so boot failed because the filesystem required for /var couldn't be found. The dracut.cmdline documentation does record that it will only activate the LVs given as "rd.lvm.lv", but I'm confused about several things. 1: The system also includes a volume group named "BackupGroup" and that group activates on boot (post-dracut). Why are those LVs activated when rd.lvm.lv is specified? 2: Why didn't Anaconda add the "var" LV to the kernel arguments? 3: This seems like a change from earlier releases, but I can't find any documentation to that effect. Under CentOS 7, after dracut had finished, the remaining logical volumes in that group would be activated. Because they aren't, currently, libvirtd cannot start any of its guests until I manually activate the group. How can I restore the old behavior of activating all of the LVs on boot?
