This hook loads the necessary modules for any raid root device,
|
|
and assembles the raid device when run.
|
|
|
|
If arrays are defined in /etc/mdadm.conf, the file will be used instead
|
|
of command line assembling.
|
|
|
|
Command Line Setup:
|
|
- for raid arrays with persistent superblocks:
|
|
md=<md device no.>,dev0,dev1,...,devn
|
|
md=<md device no.>,uuid
|
|
- for partitionable raid arrays with persistent superblocks:
|
|
md=d<md device no.>,dev0,dev1,...,devn
|
|
md=d<md device no.>,uuid
|
|
|
|
Parameters:
|
|
- <md device no.> = the number of the md device:
|
|
0 means md0, 1 means md1, ...
|
|
- <dev0-devn>: e.g. /dev/hda1,/dev/hdc1,/dev/sda1,/dev/sdb1
|
|
or 0900878d:f95f6057:c39a36e9:55efa60a
|
|
Examples:
|
|
- md=d0,/dev/sda3,/dev/sda4 md=d1,/dev/hda1,/dev/hdb1
|
|
This will setup 2 md partitionable arrays.
|
|
- md=0,/dev/sda3,/dev/sda4 md=1,/dev/hda1,/dev/hdb1
|
|
This will setup 2 md arrays with persistent superblocks.
