multibackend/6717bb8/logs/screen-n-api.txt.gz?level=TRACE#_2016-01-04_11_47_11_087 Currently observed things: 1) Manila project has no recent changes that could cause it, as well as Nova and Cinder do not have recent changes that can be suspects. 2) Error appears on attempt to attach Cinder volume to Nova VM. 3) Amount of attachments increased comparing to "ok" results of other runs before error appearance. Example: was 55, became 98 and then job timeout reached, so, it is not final count of attach attempts. 4) Nova fails to dedicated device ID for volume starting from 26th. This limit should not have been reached in normal situation. Suspect cause: reserved device IDs for Nova are not released as it was and expected. Nova has bug handling case when devide ID cannot be reserved. ** Affects: nova Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!

multibackend/6717bb8/logs/screen-n-api.txt.gz?level=TRACE#_2016-01-04_11_47_11_087 Currently observed things: 1) Manila project has no recent changes that could cause it, as well as Nova and Cinder do not have recent changes that can be suspects. 2) Error appears on attempt to attach Cinder volume to Nova VM. 3) Amount of attachments increased comparing to "ok" results of other runs before error appearance. Example: was 55, became 98 and then job timeout reached, so, it is not final count of attach attempts. 4) Nova fails to dedicated device ID for volume starting from 26th. This limit should not have been reached in normal situation. Suspect cause: reserved device IDs for Nova are not released as it was and expected. Nova has bug handling case when devide ID cannot be reserved.
