Retrieve data of boot volume
Currently I faced a serious issue with my boot volume on my VM, described here : https://community.oracle.com/customerconnect/discussion/comment/630288#Comment_630288
In short I tried to resize my boot volume from 47GB to 100GB and got the following error message:
"Edit Volume Error: The requested volumeSize 100 GB is not supported. It should be between 0 GB and 0 GB."
I then detached the volume to try again. I got the same error.
I tried to reattach the boot volume to my VM instance by typing the VM instance OCID and got:
"No instance with this OCID in the current compartment"
