Thank you both, I tried setting "--property hw_rescue_device=cdrom --property hw_rescue_bus=scsi" but it returns the same error Uploading it as raw and using it as a disk worked, although I agree it's weird Thanks again! -- Francesco Di Nucci System Administrator Compute & Networking Service, INFN Naples Email:francesco.dinucci@na.infn.it On 03/12/24 14:17, Tobias Urdin - Binero IT wrote:
Hello,
Try uploading your ISO with "--property hw_rescue_device=cdrom --property hw_rescue_bus=scsi”

Hello,
I am using Openstack 2024.1 and I have issues with an instance with a corrupted FS - I wanted to start it in rescue mode, but I'm getting stuck
After reading nova#1926601 <https://bugs.launchpad.net/nova/+bug/1926601> , downloaded System Rescue CD and created an image with properties [otherwise it always failed with "Cannot rescue a volume-backed instance (HTTP 400)"] :
openstack image create --file systemrescue-11.02-amd64.iso --disk-format iso --container-format bare --property hw_rescue_bus=virtio --property hw_rescue_device=disk systemrescuecd
Then tried to rescue the instance:
openstack --os-compute-api-version 2.96 server rescue --image systemrescuecd (my-instance-id)
Now it fails with "Instance (my-instance-id) cannot be rescued: Driver Error: Image (my-image-id) is unacceptable: Image not in a supported format"
How should I proceed?
Thanks in advance
