Not sure if i understand: You don't boot from the raid arrays, correct? These are only data or whatever arrays which you mount to /mnt/mdX?
Correct.
Have you put your raid module (raid1) in /etc/rc.conf->MODULES and have you put your array specs into /etc/mdadm.conf?
Ach, that I did not do. I also messed up and didn't mdadm -D --scan >> /etc/mdadm.conf after installing (which I did beforehand by accident, blindly following the guide I was reading, heh). What's the difference between that and -E -s?
Also the partition types should be *fd* on all raid array members.
What? I have /dev/md0 and /dev/md1 as 'ext4' type. That's bad?
That's the filesystem on the raid array. The partition type should be fd... you set that using fdisk The fd tells a system that the partition is part of a raid array. You should set it on all the partitions that makeup md0 and md1 Here is the output from sudo fdisk -l Notice under the Id column the fd type Disk /dev/sdb: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xef52ef52 Device Boot Start End Blocks Id System /dev/sdb1 * 1 12748 102398278+ 7 HPFS/NTFS /dev/sdb2 12749 12814 530145 83 Linux /dev/sdb3 12815 12880 530145 82 Linux swap / Solaris /dev/sdb4 12881 60801 384925432+ 5 Extended /dev/sdb5 12881 14186 10490413+ fd Linux raid autodetect /dev/sdb6 14187 15492 10490413+ fd Linux raid autodetect /dev/sdb7 15493 16798 10490413+ 83 Linux /dev/sdb8 16799 17452 5253223+ 83 Linux /dev/sdb9 17453 18106 5253223+ 83 Linux /dev/sdb10 18107 22023 31463271 83 Linux Disk /dev/sdc: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x05f505f4 Device Boot Start End Blocks Id System /dev/sdc1 * 1 12748 102398278+ 7 HPFS/NTFS /dev/sdc2 12749 12814 530145 83 Linux /dev/sdc3 12815 12880 530145 82 Linux swap / Solaris /dev/sdc4 12881 60801 384925432+ 5 Extended /dev/sdc5 12881 14186 10490413+ fd Linux raid autodetect /dev/sdc6 14187 15492 10490413+ fd Linux raid autodetect /dev/sdc7 15493 16798 10490413+ 83 Linux /dev/sdc8 16799 17452 5253223+ 83 Linux /dev/sdc9 17453 18106 5253223+ 83 Linux /dev/sdc10 18107 22023 31463271 83 Linux Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xea26ea26 Device Boot Start End Blocks Id System /dev/sda1 * 1 12748 102398278+ 7 HPFS/NTFS /dev/sda2 12749 12814 530145 83 Linux /dev/sda3 12815 12880 530145 82 Linux swap / Solaris /dev/sda4 12881 60801 384925432+ 5 Extended /dev/sda5 12881 14186 10490413+ fd Linux raid autodetect /dev/sda6 14187 15492 10490413+ fd Linux raid autodetect /dev/sda7 15493 16798 10490413+ 83 Linux /dev/sda8 16799 17452 5253223+ 83 Linux /dev/sda9 17453 18106 5253223+ 83 Linux /dev/sda10 18107 22023 31463271 83 Linux
