Hello, |
2 |
|
3 |
Well it's been almost a year since I tried to set up |
4 |
a simple raid1 workstation. (I.E. 2 identical drives, |
5 |
boo/root/swap only with Raid 1). So I'm starting over. |

|

I found this link: |

http://en.gentoo-wiki.com/wiki/RAID/Software |

|
10 |
Is this the best document to follow? |

(note, I'm going to try to avoid using LVM: |

Disk /dev/md127 doesn't contain a valid partition table |
47 |
<snip many more /dev/md### partitions. |
48 |
|
49 |
|
50 |
So the drives are setup identical, and are identical 2T seagate |
51 |
drivers. The md### partitions are all screwed up. So I think |
52 |
I should just nuke all the data and start over, just keeping |
53 |
the formatting. |

parted shows the drives as set up fine (???), I just need to |
83 |
erase each partition from here? Suggestions? |
