--- fixes: - | Previously when the ``ironic-python-agent`` would undergo erasure of block devices during cleaning, it would automatically attempt to erase the contents of any "Shared Device" clustered filesystems which may be in use by distinct multiple machines over a storage fabric. In particular IBM GPFS, Red Hat Global File System 2, and VmWare Virtual Machine File System (VMFS), are now identified and cleaning is halted. This is important because should an active cluster be using the this disk, cleaning could potentially cause the cluster to go down forcing restoration from backups. Ideally, infrastructure operators should check their environment's storage configuration and un-map any clustered filesystems from being visible to Ironic nodes, unless explicitly needed and expected. Please see the Ironic-Python-Agent troubleshooting documentation for more information. issues: - | Logic to guard VMFS filesystems from being destroyed *may* not recognize VMFS extents. Operators with examples of partitioning for extent usage are encouraged to contact the Ironic community.
