Hello, |
| 2 |
|
| 3 |
Ok, so It's a new gentoo install on (2) 2T sata 3 drives (Raid1). |
| 4 |
|
| 5 |
|
| 6 |
So I'm using this document as a reference: |
| 7 |
http://wiki.gentoo.org/wiki/Btrfs_native_system_root#Installing_the_MBR |
| 8 |
|
| 9 |
I ran the "o" option on both disks and it is the only deviation from the |
| 10 |
document: |
| 11 |
|
| 12 |
Command (? for help): o |
| 13 |
This option deletes all partitions and creates a new protective MBR. |
| 14 |
Proceed? (Y/N): Y |
| 15 |
|
| 16 |
So using cgdisk I end up with: |
| 17 |
|
| 18 |

|
| 43 |
/dev/sda is identical (HD are same make/model). |
| 44 |
|
| 45 |
Then : |
| 46 |
mkfs -t btrfs -L BTROOT -m raid1 -d raid1 /dev/sda3 /dev/sdb3 |
| 47 |
|
| 48 |
mkfs -t btrfs -L BOOT -m raid1 -d raid1 /dev/sdb2 /dev/sda2 |
| 49 |
|
| 50 |
|
| 51 |
Turning ON incompat feature 'mixed-bg': mixed data and metadata block groups |
| 52 |
Turning ON incompat feature 'extref': increased hardlink limit per file to 65536 |
| 53 |
Created a data/metadata chunk of size 8388608 |
| 54 |
adding device /dev/sda2 id 2 |
| 55 |
fs created label BOOT on /dev/sdb2 |
| 56 |

|
| 58 |

| 62 |
Btrfs v3.12 |
| 63 |
|
| 64 |
So far so good(?). |
| 65 |
|
| 66 |
But now it looks to me like a straight forward handbook install; OR |
| 67 |
follow the aforementioned link explicitly for sections: |
| 68 |
Root Volume and Boot Volume and Other Volumes (suggestions for |
| 69 |
Other Volumes (sub-volumes) are welcome. |
| 70 |
|
| 71 |
|
| 72 |
Another question. I want to run openrc not systemd. All of that |
| 73 |
init scripts looks like systemd. How and where would I modify that |
| 74 |
page if I intend to use openrc, if at all? |
| 75 |
|
| 76 |
|
| 77 |
all discussion, comments and suggestions are welcome. |
