We should check why the mountpoint is busy, but a quick fix may be usi= ng the --lazy option:
umount --lazy /mountpoint
That's only available on newer kernels, for the el7 slaves it's not yet=

You are right, from the manual: -l, --lazy Lazy unmount. Detach the filesystem from the filesystem hier= archy now, and cleanup all references to the filesystem as soon as it is no= t busy anymore. (Requires kernel 2.4.11 or later.) I just confused 2.4.11 for 4.2.11... should be ok to use it
