Mitaka Series (1.1.0 - 1.2.x) Release Notes¶
Limits the memory usage of
qemu-img convertcommand to 1 GiB to avoid it from causing the host machine to fail due not enough ram.
Fix two root device hints, ‘wwn_with_extension’ and ‘wwn_vendor_extension’, that were implemented and documented, but were not added to the list of supported root device hints, and thus fail validation.
The driver_internal_info internal setting
agent_continue_if_ata_erase_failedallows operators to enable disk cleaning operations to fallback from a failed ata_erase operation to disk shredding operations.
On start up wait up to 30 seconds for the first disk device suitable for deployment to appear. This is to fix both inspection and deployment on hardware that takes long to initialize (e.g. some RAID devices).
IPA will now attempt to unlock a security locked drive with a ‘NULL’ password if it is found to be enabled, however this will only work if the password was previously set to a ‘NULL’ value, such as if a failure during a previous ata_erase sequence.
Potential command failures in the secure erase process are now captured and raised as BlockDeviceEraseError exceptions.
The “has_carrier” flag was added to the network interface information.
Fixes bug where the user specified disk_label is ignored with partition images in agent drivers.
Inspection code now waits up to 1 minute for all NICs to get their IP addresses. Otherwise inspection fails for some users due to race between DIB DHCP code and IPA startup. See https://bugs.launchpad.net/bugs/1564954 for details.
During inspection wait only for a PXE booting NIC to get its IP by default. Introduce a new “inspection_dhcp_all_interfaces” option to enable waiting for all interfaces instead.
Stop checking the “has_carrier” field when waiting for NIC’s to get IP addresses, as it might be set to “False” when the interface is being configured.
Add new ‘system_vendor’ information to data - Add hardware vendor information(product name, serial number, manufacturer) to data. This will be able to give Ironic Inspector hints to detect driver.
Add support for partition images in IPA. This commit adds the ironic-lib as the requirement for the IPA package.
Debug logging can now be enabled by setting “ipa-debug” kernel parameter.
Root device hints extended to support the device name.
Add a new sync() command to the standby extension. When invoked, the new command is responsible for flushing the file system buffers to the disk.
dmidecode output produces less parsing errors and logs common and normal output like “No Module Installed” or “Not Installed” in debug instead of error.
IPA will now advertise IP address via which the Ironic API is routed instead of using the first available. See https://bugs.launchpad.net/ironic-python-agent/+bug/1558956.
This enables virtual media deploy even if virtual floppy device name is capitalized to “/dev/disk/by-label/IR-VFD-DEV”. see https://bugs.launchpad.net/ironic/+bug/1541167 for details.
Stop using SYSRQ when performing the in-band reboot or power off because it has a similar effect to a hardware reset button/power switch and can be problematic on some hardware types. Instead, reboot/power off the node via the “poweroff” and “reboot” commands (soft power action).
Ensure block devices are detected by the host OS before listing them.
Root device hints now also inspect ID_WWN_WITH_EXTENSION and ID_WWN_VENDOR_EXTENSION from udev.
CoreOS image builder now runs IPA in a chroot, instead of a container. systemd-nspawn has been adding more security features that break several things IPA needs to do (after all, IPA manipulates hardware), such as using sysrq triggers or writing to /sys.
Adds support for streaming raw images directly onto the disk. This avoids writing the image to a tmpfs partition before writing it to disk, which also enables using images larger than the usable amount of RAM on the machine IPA runs on. Pass stream_raw_images=True to the prepare_image command to enable this; it is disabled by default.
Adds support for setting proxy info for downloading images. This is controlled by the proxies and no_proxy keys in the image_info dict of the prepare_image command.
IPA now supports Linux-IO as an alternative to tgtd. The iSCSI extension will try to use Linux-IO first, and fall back to tgtd if Linux-IO is not found or cannot be used.
The CoreOS image builder now uses the latest CoreOS stable version when building images.
Now that IPA runs in a chroot, any operator tooling built around the container may need to change (for example, methods of getting a shell inside the container).
Fixes configdrive creation for MBR disks greater than 2TB.
Makes tgtd ready status detection more robust.
Fixes an issue using the “logs” inspection collector when logs contain non-ascii characters.
Raw images larger than available of RAM may now be used by passing stream_raw_images=True to the prepare_image command; these will be streamed directly to disk.
System random is now used where applicable, rather than the default python random library.
