Creating a Raid 1 Mirror
mdadm --zero-superblock /dev/sdb mdadm --zero-superblock /dev/sdc
Create the array:
mdadm --create /dev/md0 --chunk=4 --level=1 --raid-devices=2 /dev/sdb /dev/sdc
That's it! Create the file system and you're done. Using 4k chunk size.
Disassemble / stop an array
mdadm --stop /dev/md0
Reassemble an array
mdadm --assemble --scan
You can assemble an array like:
mdadm --assemble /dev/md0 /dev/sdb /dev/sdc
