The kernel is waiting for mdmon (mdadm as a background task) to step
through the stripes. mdmon died and the kernel will wait forever.

Probably. Others have fixed this by disabling selinux for the reshape.
Don't forget to specify --backup-file again on the command line. (I
don't use selinux myself, so I can't be more specific.)
In the future, consider not using a backup file at all -- mdadm
generally leaves enough dead space on devices to avoid the need.

Shouldn't be. Report back if it is.
