For those who do not use Greyhole, you can disable it. This is based on the fact you never have used it by enabling 'Uses pool' on any share. Recommend using extreme caution as this could have unpredictable results.
Perform the following steps as user '''root''' (Fedora 19Ubuntu):
systemctl disable amahiupdate-rc.d -f greyhole.serviceremove
rm /etc/monit.d/greyhole.conf
systemctl service monit restart monit.service systemctl service greyhole stop amahi-greyhole.service
'''DO NOT''' attempt to remove the Greyhole package as it is a dependency of the HDA software. Doing so will break your HDA.
