6.1.0
^^^^^

Bug Fixes

* Bug #1967157 (https://bugs.launchpad.net/nova/+bug/1967157): Fixed
  extending LUKS and LUKSv2 host attached encrypted volumes. Only LUKS
  v1 volumes decrypted via libvirt were working, but now all LUKS
  based in-use encrypted volumes can be extended.

* NVMe-oF connector bug #1964395 (https://bugs.launchpad.net/os-
  brick/+bug/1964395): Fixed dependence on a specific nvme cli version
  for proper detection of devices when attaching a volume.

* NVMe-oF connector bug #1964388 (https://bugs.launchpad.net/os-
  brick/+bug/1964388): Fixed corner case where it could return the
  wrong path for a volume, resulting in attaching in Nova the wrong
  volume to an instance, destroying volume data in Cinder, and other
  similarly dangerous scenarios.

* NVMe-oF connector bug #1964385 (https://bugs.launchpad.net/os-
  brick/+bug/1964385): Fixed disappearance of volumes/devices from the
  host, with potential data loss of unflushed data, when network
  issues last longer than 10 minutes.

* NVMe-oF connector bug #1964380 (https://bugs.launchpad.net/os-
  brick/+bug/1964380): Fixed support for newer nvme cli exit code when
  trying to connect to an already subsystem-portal.

* NVMe-oF connector bug #1964383 (https://bugs.launchpad.net/os-
  brick/+bug/1964383): Fixed not being able to attach a volume if
  there was already a controller for the subsystem.

* NVMe-oF connector bug #1965954 (https://bugs.launchpad.net/os-
  brick/+bug/1965954): Fixed extend of in-use replicated volumes with
  a single replica not growing the RAID

* NVMe-oF connector bug #1964590 (https://bugs.launchpad.net/os-
  brick/+bug/1964590): Fixed extend failure of in-use volumes with
  some Cinder drivers.

* NVMe-oF connector bug #1903032 (https://bugs.launchpad.net/os-
  brick/+bug/1903032): Fixed not flushing single connection volumes on
  some Cinder drivers.

* NVMe-oF connector bug #1961102 (https://bugs.launchpad.net/os-
  brick/+bug/1961102): Fixed leaving controller devices (i.e.,
  /dev/nvme0) behind on hosts.  Now NVMe-oF subsytems are disconnected
  when disconnecting volumes if the subsytem doesn't have additional
  volumes present in the host.
