How to delete mdadm Soft RAID and precautions

Delete the entire RAID:

Mdadm/dev/md0 -- fail/dev/sdb -- remove/dev/sdb
Mdadm/dev/md0 -- fail/dev/sdc -- remove/dev/sdc
Mdadm/dev/md0 -- fail/dev/sdc -- remove/dev/sdd
Mdadm/dev/md0 -- fail/dev/sde -- remove/dev/sde
Mdadm/dev/md0 -- fail/dev/sdf -- remove/dev/sdf

Mdadm -- stop/dev/md0
Mdadm -- remove/dev/md0

Mdadm -- misc -- zero-superblock/dev/sdb
Mdadm -- misc -- zero-superblock/dev/sdc
Mdadm -- misc -- zero-superblock/dev/sdd
Mdadm -- misc -- zero-superblock/dev/sde
Mdadm -- misc -- zero-superblock/dev/sdf

That is, delete all the devices in the RAID and then stop the RAID.

To prevent raid from being started during system startup
Rm-f/etc/mdadm. conf
Rm-f/etc/raidtab

Check whether there are other mdad startup methods in the System Startup File.
Vi/etc/rc. sysinit +/raid \ c
