If setting that the RAID1+0 devices are mounted automatically when system starts
up in /etc/fstab, clear the setting by editing /etc/fstab. If the RAID1+0 device is
deleted without above, the system may not start up normally.

Note Unmount the RAID1+0 device, if mounted

If the RAID device is configured as physical volume in a part of LVM (Logical Volume
Manager), remove the RAID1+0 device from LVM before clearing the striping array.

It is recommended to back up the user data as required.
