What I have to change?
I am guessing, because I don't know exactly what it is, but initramfs requires that the use of raid is switched on. In particular /etc/mdadm/mdadm.conf should have some records in it that list define the arrays, and then update-initramfs gets them set up. Mine is like this DEVICE partitions CREATE owner=root group=disk mode=0660 auto=yes metadata=1 MAILADDR root ARRAY /dev/md0 level=raid1 num-devices=2 name=0 UUID=c4887a6b:db58843e:209f5cfe:35d78da6 ARRAY /dev/md1 level=raid1 num-devices=2 name=1 UUID=210a27fe:06a1f486:1907fc2f:b4172f32 ARRAY /dev/md2 level=raid1 num-devices=2 name=2 UUID=1508c72f:91e305da:a71136c7:f7b25b0b ARRAY /dev/md3 level=raid0 num-devices=2 name=3 UUID=9df2ce56:80fd9cd9:6265d55b:9dddda0b ARRAY /dev/md4 level=raid5 num-devices=3 spares=1 name=4 UUID=9ade8b08:39950784:df2dcf3f:18e8cfa9 I don't know exactly how it works when you replace a failed drive, but I think (inside the initramfs) mdadm looks for disks with the UUID in the metadata someplace. So I think the process is probably to start your system and then add the new disk that replaced the broken one with mdadm -A -- Alan Chandler http://www.chandlerfamily.org.uk -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
