Comment 6 for bug 1523435

Hi, Roman.

Unfortunately, I have no that environment, but have tried with other setup. Problem is reproduced

MOS 8.0, ISO #361

Environment:
    * 50 baremetal nodes
    * Ceph *is not* used
        - Cinder LVM over iSCSI for volumes is enabled, rest of checkboxes are disabled
    * Ceilometer, Murano and Sahara *are* installed
    * Each node has 32142MB RAM, 12 CPU

So as you can see, environment is similar but Ceph is not used. I've tried the same usecase as mentioned, and succeed to reproduce:
    * Failed instance is 18807ac1-c130-4c56-bc04-f7b047076e95
    * Volume snapshot is af872626-e0bb-4b00-b9f7-6c5bb0f620e1
    * Snapshot is made from volume 9e165e5c-3ba1-4048-affd-bdfee3059444

Error:
    * Message: Build of instance 18807ac1-c130-4c56-bc04-f7b047076e95 aborted: Block Device Mapping is Invalid.
    * Code: 500

I cannot create diagnostic snapshot due to https://bugs.launchpad.net/fuel/+bug/1529182 so I've gathered all possible logs (not *.gz). Please find them here:
