9.0.0
^^^^^


New Features
************

* Users can specify a list of devices to be skipped during the
  cleaning process or be chosen as the root device in property field
  "skip_block_devices".


Known 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.


Upgrade Notes
*************

* No longer supports network boot of instances
  ("boot_option=netboot"). This feature is dropped from Ironic in the
  Zed cycle.


Bug Fixes
*********

* Fixes an issue where arguments were not passed to clean steps when
  a manual cleaning operation was being executed. The arguments are
  now passed in appropriately.

* Fixes GenericHardwareManager to find network information for
  bonded interfaces if they exist.

* Fixes failures with handling of Multipath IO devices where
  Active/Passive storage arrays are in use. Previously, "standby"
  paths could result in IO errors causing cleaning to terminate. The
  agent now explicitly attempts to handle and account for multipaths
  based upon the MPIO data available. This requires the "multipath"
  and "multipathd" utility to be present in the ramdisk. These are
  supplied by the "device-mapper-multipath" or "multipath-tools"
  packages, and are not requried for the agent's use.

* Fixes non-ideal behavior when performing cleaning where
  Active/Active MPIO devices would ultimately be cleaned once per IO
  path, instead of once per backend device.

* Fixes discovering WWN/serial numbers for devicemapper devices.

* 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.


Other Notes
***********

* Block devices properties reported by udev are now collected with
  the ramdisk logs.

* The ramdisk logs now contain an "lsblk" output with all pairs in
  the new "lsblk-full" file.

* The agent will now attempt to collect any multipath path
  information and upload it to the agent ramdisk, if the tooling is
  present.
