====== RAID - mdadm - Stop and delete a RAID array ======

To completely remove a raid array it has to be stopped first before it can be removed.

<code bash>
mdadm --stop /dev/md0
mdadm --remove /dev/md0
</code>

----

===== Delete the superblock from the individual drives =====

<code bash>
mdadm --zero-superblock /dev/sda
</code>

----

===== Copy the partitions to other drives =====

When using RAID, such as RAID1 arrays, where identical partitions exist on both drives it can be useful to copy the partitions from sda to sdb:

<code bash>
sfdisk -d /dev/sda | sfdisk /dev/sdb
</code>

<WRAP important>
**WARNING:**  This will dump the partition table of sda, removing completely the existing partitions on sdb, so be sure you want this before running this command, as it will not warn you at all!
