MD devices are created using the Create
mode of mdadm
.
You need to specify the raid device to create, the raid mode (raid0, raid1, raid5, raid6 etc) and the component devices.
You can also configure many aspects of your array:
- device name
- name or label
- RAID-level
- superblock
- chunk size
- rounding
- layout
- bitmap
- write-mostly
- partitionable
One question that frequently comes up with linux raid is:
"Why does linux raid do 'resync' when I create a clean array? Can I skip that?"
The answer is usually "NO". For more details see Initial Array Creation
