With Grub installed on both disk. Shutdown the machine, pull a disk. Start it up trying to mount with -o degraded (or kernel rootflags=). Yesterday I tried this with this new OpenSuse release, but I couldn't see if it worked. systemd or maybe dracut was in the way and I didn't get any output or a prompt to investigate to see what is going on. Even with debug on. But I'll give it an other try soon on a system I do understand/know (Debian-based). I've recently learned adding recovery might help too so I hope I can test that. _______________________________________________ Freedombox-discuss mailing list Freedombox-discuss@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/freedombox-discuss
