Cloud-Init Docs

[XN-Matt]

The docs for cloud-init are a little thin on the ground being such a new feature.

What is the expected behaviour for this in proxmox? Should the cloud-init drive remain always connected? if so, after the machine is shut down and then started again, it fails with the error:

qemu-img: Could not open '/dev/vg-1/vm-xxx-cloudinit': Could not open '/dev/vg-1/vm-xxx-cloudinit': No such file or directory
TASK ERROR: command 'set -o pipefail && genisoimage -R -V cidata /run/pve/cloudinit/xxx/ | qemu-img dd -n -f raw -O raw 'isize=0' 'osize=0' 'of=/dev/vg-1/vm-xxx-cloudinit'' failed: exit code 1

If not, as proxmox knows the VM has stopped, can it not remove that automatically instead of leaving in a half broken state?

Either way, if we know we need to delete it on a shutdown, that's OK too but would rather work with the expected process than one that we're getting right now.

this should not happen, can you post the vm config and the storage config?

 

[XN-Matt]

Where do you want the storage config from?

VM:

agent: 1
boot: dcn
bootdisk: virtio0
cipassword: [removed]
ciuser: [removed]
cores: 3
hotplug: disk,network,usb,memory,cpu
ide0: storage-1:vm-106-cloudinit,media=cdrom
ipconfig0: ip=x.x.x.x/24,gw=x.x.x.x
memory: 2048
name: xxxxxx
net0: virtio=xx:xx:xx:xx:xx:xx,bridge=vmbr0
numa: 1
onboot: 1
ostype: l26
scsihw: virtio-scsi-pci
searchdomain: xxxxx
smbios1: uuid=34b69428-f82e-4e3f-8a1f-f868d2b6769c
sockets: 1
sshkeys: [removed]
tablet: 0
virtio0: storage-1:vm-xxx-disk-1,cache=writeback,size=30G

 

[dcsapak]

Where do you want the storage config from?

/etc/pve/storage.cfg

 

[XN-Matt]

For where it is stored.

iscsi: c1-sp1
    portal x.x.x.x
    target c1-sp1
    content images

lvm: storage-1
    vgname vg-1
    base c1-sp1:0.0.0.scsi-xxxxxx
    content rootdir,images
    shared 1

 

[dcsapak]

what does lvs say?

 

[XN-Matt]

For that cloud-init:

  vm-106-cloudinit vg-1 -wi-ao----   8.00m

It has been running since it was used. If I was to stop the VM and then start again, it would fail.

Would you like the output from the command after doing that?

 

[dcsapak]

Would you like the output from the command after doing that?

yes please

 

[XN-Matt]

Done:

  vm-106-cloudinit vg-1 -wi-------   8.00m

 

[dcsapak]

ok i could reproduce it and find the error, i sent a patch to the pve-devel list

 

[XN-Matt]

Great thanks. Will wait for that to be pushed out to an update.
