Scenario:
host a is the master
host b is a replication slave
host c is to become a second replication slave
there's no full dump from host a

One possibility I can think of:
- stop slave on host b
- run the dump on host b
- note its position in host a's binlogs using "show slave status"
- restore the dump on host c
- start c slaving using the binlog name and position from "show slave status"
Will that work?
Yes.
Is there a way to do this *without* stopping replication on host b?
No, unless you have a snapshot-capable file system like LVM, and even then there
are caveats. Just be aware of which columns of SHOW SLAVE STATUS mean what --
there are three sets of binlog coordinates in that output. (There's a note on
the online manual that should make it clear).
