Ironic: Deploy user image failed use dirver fuel_ipmitool or fuel_ssh

[tomson]

I enrolled an ironic node with fuel_ipmitool/fuel_ssh as the driver.And then i used disk-image-create created a user image. Also i used glance image-create registered it with extra info ‘[{"name": "sda", "extra": [], "free_space": 11000, "type": "disk",
"id": "vda", "size": 11000, "volumes": [{"mount": "/", "type":
"partition", "file_system": "ext4", "size": 10000}]}]’

When i used nova boot to boot an instance, the ironic node could powered on and booted with deploy image. But then it reported errors and powered off.

Error information:

 fuel_agent.utils.utils [-] Trying to execute command: mount -t ext2 /dev/sda3 /tmp/tmpsmfXTZ

I tried many times, it seems about the user images. I got that fuel_ipmitool only support raw format user images.
Now I wonder how to build a usable user image.

below is how i create a user image.

disk-image-create -a amd64 -p grub2-common,grub-pc,grub-gfxpayload-lists,emacs24-nox,parted vm ubuntu-minimal -o ubuntu-minimal -t raw

In this way, the ironic-conductor log report errors:

Exit code: 32
Stdout: ''
Stderr: 'mount: wrong fs type, bad option, bad superblock on /dev/sda3,\n missing codepage or helper program, or other error\n In some cases useful info is found in syslog - try\n dmesg | tail or so\n\n'

when i execute this command:
disk-image-create -a amd64 -p grub2-common,grub-pc,grub-gfxpayload-lists,emacs24-nox,parted baremetal ubuntu-minimal -o ubuntu-minimal -t raw

it output three files:ubuntu-minimal.initrd ubuntu-minimal.raw ubuntu-minimal-2nd.vmlinuz.

I register ubuntu-minimal.raw
glance image-create --name myimage --disk-format raw --container-format bare \
--file ubuntu-minimal.raw --visibility public
glance image-update 8304e68e-1df8-403b-8c85-1fb6b09bdc55 --property cpu_arch=x86_64 \
--property hypervisor_type="baremetal" \
--property fuel_disk_info='[{"name": "sda", "extra": [], "free_space": 110000, "type": "disk","id": "vda", "size": 110000, "volumes": [{"mount": "/", "type":"partition", "file_system": "ext4", "size": 30000}]}]'

at last i use this image to boot an instance successfully, but ubuntu os didn't work.

Hi tomson,
problem is that disk-image-create uses ext4 but fuel-agent uses ext2 as a file system to mount. So you need or ext2 as image fs type or wait while developers add other fs to fuel-agent.
