I found a problem in multipath-tools. The kpartx utility failed with a partition >2TB. There is a fix from redhat for that. I sent it to the author and he included it for future versions. As this is quite essential, I thought you might want to add the patch for the current version in gentoo as well. Enclosed you find a patched kpartx from redhats multipath-tools 0.4.7 and the patch-files. I am not shure if they fit directly onto the version that gentoo uses, but it shouldn't be a problem to adopt them. Reproducible: Always
Created attachment 133645 [details] patched kpartx and patchfiles This is a patched kpartx and the patchfiles.
This bug is for multipath-tools-0.4.7-r2
Fixed in upstream 0.4.8, coming to the gentoo tree shortly.
