Description

RHEL 6.4 ceph 0.67.4

Ceph-disk prepare fails when setting up encrypted disks when the data and journal are located on the same drive. After initializing the journal it seems to be recognized by udev and cryptsetup sets up a mapping. Then when the drive is partitioned for the data partition, the kernel fails to reread the partition table because now the device is held active by the existing dmcrypt mapping for the journal partition.

I added a pair of dmcrypt_unmap calls which allowed the disk prepare to complete successfully.
