Works on a boot device as long as you use old 0.90 format superblock on your md devices. You can boot with autodetect or specify how to assemble root raid fs on command line like: # cat /proc/cmdline BOOT_IMAGE=18/3 ro root=902 md=2,/dev/sda2,/dev/sdb2 raid=noautodetect # ls -l /dev/md2 brw-rw---- 1 root disk 9, 2 Apr 12 2015 /dev/md2 # Regards, /Karl Hammar ----------------------------------------------------------------------- Aspö Data Lilla Aspö 148 S-742 94 Östhammar Sweden
