Somehow one of my hard drives got a raid header on it, causing it to |
| 2 |
start automatically sometimes when not needed. It's on /dev/hda, my |
| 3 |
main system disk, which is not RAID at all. Running mdadm -E /dev/hda I |
| 4 |
get: |

The other disks in the array (sda and sdb) are two SCSI disks which are |
| 39 |
currently unused, but have some raid partitions on them (mostly used for |
| 40 |
playing with other distros). |
| 41 |
|
| 42 |
It also looks like my system is confusing /dev/hda and /dev/sda or |
| 43 |
something? Maybe this is caused by using evms? All I know is when I |
| 44 |
installed ubuntu on the SCSI disks to play around I found that it |
| 45 |
wouldn't install properly because after partitioning the disks it had a |
| 46 |
RAID device already up and running, which turned out to be /dev/hda in a |
| 47 |
RAID1 with a second device missing. |
| 48 |
|
| 49 |
None of the partitions on the disk are marked as type raid-autodetect |
| 50 |
either. I'm hoping that there's a magic offset that I can dd /dev/zero |
| 51 |
to to knock the raid header off without nuking my system disk. |

Thanks. |
