The sollution to the problem was simple. The lvm tools are hardcoded (from lvm_dir_cache.c) to only look for specific directories when scaning for lvm disks. For network block devices lvm looks only in /dev/nb/*, while my Gentoo kernel created /dev/nbd/*. A simple fix was to make a link /dev/nb->/dev/nbd and it worked. I did not find anything about this in the howto or man-pages. //Anders > Hello, > How can I make lvm to recognize my network block devices?
