Comment 7 for bug 1444459

The issue occurs when using a Ceph journal partition. The agent calculates how to subdivide the journal space [0] and this calculation results in a floating point number (e.g 1 journal volume of 10GB and 3 osds will result in 3 journal partitions of size 3333.33). This size gets used in a dd command which fails. See the fuel-agent log [1] for a failed node.

Leontiy, could you please attach the bootstrap/fuel-agent.log from one of your failed nodes?
