As Harald suggested we should add: diff --git a/modules.d/90lvm/module-setup.sh b/modules.d/90lvm/module-setup.sh index c4db779a..6ca4ee44 100755 --- a/modules.d/90lvm/module-setup.sh +++ b/modules.d/90lvm/module-setup.sh @@ -43,7 +43,7 @@ cmdline() { } installkernel() { - instmods dm-snapshot + hostonly='' instmods dm-snapshot } Reproduced on RHEL-7.4 GA using the steps in comment 0. Verified using dracut-033-535.el7 using the same steps, the dm-snapshot kernel module was present in the initrd even when no LVM snapshot was created on the system. After creating a new snapshot and restarting, the system started without errors. Moving to VERIFIED.
