Bug Description
OS-Brick disconnect_volume code assumes that the use_multipath parameter that is used to instantiate the connector has the same value than the connector that was used on the original connect_volume call.
Unfortunately this is not necessarily true, because Nova can attach a volume, then its multipath configuration can be enabled or disabled, and then a detach can be issued.
This leads to a series of serious issues such as:
- Not flushing the single path on disconnect_volume (possible data loss) and leaving it as a leftover device on the host when Nova calls terminate-
- Not flushing the multipath device (possible data loss) and leaving it as a lefover device similarly to the other case.
| summary: |
- Flushing issues when multipath config has changed + iSCSI: Flushing issues when multipath config has changed |
