Block Device Mapping is Invalid
I have installed DevStack recently. When I try to create a new instance I get this error msg:"Block Device Mapping is Invalid". I found out that there is an item,"loop1", on my block device list which my total volume size is limited to the free space of it. In another word, when I try to create an instance with volume size larger than the free space of "loop1", I get the error message. How can I solve this problem? or how can I increase the loop1 volume size? https://i.stack.imgur.com/lnEWj.jpg (image description)
IMO the easiest solution is creating another loop device and adding it to the volume group.
Thanks for your time. May I know exactly how?
For example (I haven't tried it; might be inaccurate):
You can also look for losetup in the devstack log file for inspiration.
