The ``[workarounds]/rbd_volume_local_attach`` configuration option has been
|
|
introduced. This can be used by operators to ensure RBD volumes are
|
|
connected to compute hosts as block devices. This can be used with
|
|
the ``[worarounds]/disable_native_luksv1`` configuration option to
|
|
workaround recently discovered performance issues found within the
|
|
`libgcrypt library`__ used by QEMU when natively decrypting LUKSv1
|
|
encrypted disks.
|
|
|
|
This workaround does not currently support extending attached volumes.
|
|
|
|
This workaround is temporary and will be removed during the W release once
|
|
all impacted distributions have been able to update their versions of the
|
|
libgcrypt library.
|
|
|
|
.. warning:: Operators must ensure no instances are running on the compute
|
|
host before enabling this workaround. Any instances with attached RBD
|
|
volumes left running on the hosts will fail to migrate or stop after this
|
|
workaround has been enabled.
