Hi, harald It has nothing to do with the udev rules. There's two issues: 1) 90multipath install multipath.sh to pre-trigger hook, but seems /dev/mapper/mpathX depends on /dev/dm-* population which will be created after udev trigger. 2) fstab-sys call wait_for_dev /dev/mapper/mpathb in initqueue, /dev/mapper/mpathb does not geting change to create, so dracut drop to emergency shell. I'm not sure what's the right way to resolve this, move multipath.sh to pre-mount hook looks resolve the issue 1), how to resolve the issue 2)? comment out it works, but it looks not a right fix. I'm not familiar with multipath, please correct me for anything wrong. -- Thanks Dave -- To unsubscribe from this list: send the line "unsubscribe initramfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
