Failed to create instance Error: Can't find ext4 filesystem?
I have followed installation guide from this link http://docs.openstack.org/icehouse/install-guide/install/apt/content/nova-compute.html (http://docs.openstack.org/icehouse/in...)
I have successfully configured 3 nodes controller, compute and network all using ubuntu server 14.04 on virtualbox. In horizon I can see that my instance has been assigned an IP address but will just keep on spawning.
I had this error when creating an instance (compute bash not in any logs) * This is right after I press enter on nova boot from controller node
VFS: Can't find ext4 filesystem
FAT-fs bogus number of reserved sector
unexpected reply
I believed I have exhausted google but found little regarding this error. Could someone please shed light or point me to a direction on how I can troubleshoot this error.
Error logs appeared on the compute bash when I run nova boot from the controller.
I have followed the recommended/default settings when installing base OS.
Here's what I get when running fdisk -l

Hi, I am running Juno with 3 node cluster. Everything worked fine with adding VMs, but now I added new compute node, launching VM on the newer node fails giving error message: [ 709.761962] EXT4-fs (nbd13): VFS: Can't find ext4 filesystem [ 709.762119] EXT4-fs (nbd13): VFS: Can't find ext4 files
I get error for libvirt also, so am confused whether the issue is with disk creation or libvirt unable to configure console monitor.
The VFS error has nothing to do with disk creation. On my part it was misconfiguration of some configuration on my controller and compute node. I've noticed that even with the VFS error I can still launch intances and attach new compute nodes. Check your new compute node configurations.
