Hi, I have an Rocky OpenStack platform. I used ironic-python-agent-builder to build a ipa.initramfs image. I called the clean API to erase my baremetal node disk. But it was failed. I traced the ipa source code, and got it used 'hdparm -I /dev/sdx' to check if the device is frozen [image: image.png] my device is frozen, then I switched to another SSD, and it's not frozen but it was also failed, [image: image.png] I don't know if I need to erase my bare metal nodes' block devices in product environment. If so, how to make it successful? Ankele -------------- next part -------------- An HTML attachment was scrubbed...
