Hi, I have a bi-opteron box running a 64 bits 2.6.4 and 32 bits debian testing. it seems translating ioctl fails so even dmsetup version does not work. full details at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=234451 reported by someone else. I can try patches if you send them to me. Cheers, Mik Please CC me. -- Mickael Marchand, Ingenieur de recherche CNRS Service Informatique, Institut Fourier - UFR Maths Tel : 0476635655 Fax : 0476514478
