Software RAID-5 does indeed protect against a disk failure.

Don't worry about it. Remake the whole array with mkraid --force --dangerous-no-resync. Then mark the really failed disk or its replacement as faulty with raidsetfaulty. Then take it out with raidhotremove, then put it back wit raidhotadd. It'll be resynced from the oter two.

Or, as you're using mdadm anyway:

mdadm -A -f /dev/md? <list of disk devices>
