This is the clean way to handle this. But you can also use udev to do this
at boot. From what I found on the mailing list and made working before
using GUID :

cat > /etc/udev/rules.d/89-ceph-journal.rules << EOF
KERNEL=="sda?" SUBSYSTEM=="block" OWNER="ceph" GROUP="disk" MODE="0660"
KERNEL=="sdb?" SUBSYSTEM=="block" OWNER="ceph" GROUP="disk" MODE="0660"
KERNEL=="sdc?" SUBSYSTEM=="block" OWNER="ceph" GROUP="disk" MODE="0660"
