Well, your root is inside the array. So you won't be able to boot without the array assembling in the initramfs, which needs manual intervention to supply the backup file. If your hosting service provides access to the boot console, you could do this with "rd.shell" or whatever kernel option tells your initramfs to drop into a rescue console. Then you could manually assemble and resume booting. This would be true even if you had properly specified a backup file outside the array. I suspect this was one of the motivations for the enhancement to modern mdadm & kernels to avoid the backup file for many cases by manipulating the data offset. Such a reshape in progress can be automatically assembled without special options during boot. Plus it is faster -- one third fewer I/O operations.
