Hi I have a working Fileserver with Suse Linux 7.3 installed. There are 3 SCSI Hard Disks with Partitions on it (sda<i>, sdb<i> and sdc<i>). Now i want to upgrade to Suse Linux 9.0, but not as an Update (risky! If something fails, i have no working fileserver for hours or days!). Therefore i installed a 4. Harddisk, with a SCSI-Id greater than the three others (=> sdd). Then i did a new Installation of Suse Linux 9.0 to sdd1 with puting GRUB as bootmanager to sdd. All went fine until after installing from the first CD. The Reboot, necessary at this point did not work. Of course i told the BIOS to boot from the 4. SCSI Harddisk. The boot manager GRUB was found on the 4. SCSI Harddisk. A Linux system was found, but when the root Filesystem should be mounted, this was not possible! I got the Message "Cannot mount Root Filesystem". Luckily i could reboot my old 7.3 Linux from sda. But what did i do wrong? -- Juergen Pfeiffer SesKion Softwareentwicklung und System Konzeption GmbH Tel: +49-711-99058-14 Karlsruher Str. 11/1 Fax: +49-711-99058-27 D-70771 Leinfelden Echterdingen http://www.seskion.de
