LVM not, the MD-Layer does if you patch it. Such a patch has been in development by and been finished by ca 70% when I notices that Ingo Molnar, the maintainer of the MD-Layer had already written such a patch which RedHat hides in it's kernel RPM. Download their kernel SRPM and look for two of the thousands of patches that contain 'multipath' in their name. Christoph -- Of course it doesn't work. We've performed a software upgrade.
