I have a software raid 1 (2 disks) of CentOS 7

I want to make a working "copy" of this setup to another disk of the same size to another SSD and have it be bootable etc... Then edit something to turn off the RAID part as its only 1 disk. Or Run with the 1 disk and it will just think the second disk is failed.

so can I just do "dd if=/dev/sda of=/dev/sdd" and that is all ? Put that disk in another machine and it runs?

where sda is the first raid disk, sdb is second raid disk, sdc is something else not related and sdd would be where the disk loads as USB.

Thanks,

Jerry
