Subject: ceph-deploy osd prepare error
I am following the quick=start guides on debian wheezy. When attemping
ceph-deploy osd prepare, I get an error (umount fails). The disk is partitioned and the
filesystem is put on it, and is left mounted
under /var/local/temp/xxxxxxx, but the OSD creation fails. How can I
debug this?
