Do you mind giving the full failed logs somewhere in fpaste.org along with some os version details?
 There are some known issues on RHEL,  If you use 'osd prepare' and 'osd activate'(specifying just the journal partition here) it might work better.

Not multipath if you mean using the multipath driver, just trying to setup OSDs which use a data disk and a journal ssd. If I run just a disk based OSD and only specify one device to ceph-deploy then it usually works although sometimes has to retry. In the case where I am using it to carve an SSD into several partitions for journals it fails on the second one.
