Public bug reported: Description =========== When attaching block devices n-api will call out to the n-cpu service hosting an instance and attempt to reserve a block device name via reserve_block_device_name. This call also creates the initial BDM record within the database. RPC timeouts, seen by n-api as exceptions can then result in stale BDM records persisting in the database.
Steps to reproduce ================== 1. Attach a volume to an instance, ensuring any call to reserve_block_device_name takes longer than the configured RPC timeout within the environment. Expected result =============== The RPC timeout is hit and any BDM records created by the n-cpu service are removed by n-api. Actual result ============= The RPC timeout is hit but the BDM records persist. Environment =========== 1. Exact version of OpenStack you are running. See the following list for all releases: http://docs.openstack.org/releases/ Master. 2. Which hypervisor did you use? (For example: Libvirt + KVM, Libvirt + XEN, Hyper-V, PowerKVM, ...) What's the version of that? N/A 2. Which storage type did you use? (For example: Ceph, LVM, GPFS, ...) What's the version of that? N/A 3. Which networking type did you use? (For example: nova-network, Neutron with OpenVSwitch, ...) N/A Logs & Configs ============== Invalid bdm record remains when reserve_block_device_name rpc call times out https://bugzilla.redhat.com/show_bug.cgi?id=1752734 ** Affects: nova Importance: Undecided Assignee: Lee Yarwood (lyarwood) Status: In Progress ** Tags: compute volumes ** Tags added: compute -- You received this bug notification because you are a member of Yahoo!
