Bug Description
When using the thinlvm driver, if the cinder-volumes VG is rounded to the GB (eg. using a 100G sized PV for the VG), cinder fails to allocate the volumes pool within it with the following error:
Command: sudo cinder-rootwrap /etc/cinder/
Exit code: 5
Stdout: ''
Stderr: ' Volume group "cinder-volumes" has insufficient free space (25599 extents): 25600 required.\n'
To reproduce:
1. truncate -s 100G backingfile
2. losetup -f backingfile
3. vgcreate cinder-volumes /dev/loopX
4. configure cinder with the thinlvm driver
5. create a new volume in cinder
| summary: |
- thinlvm driver fails to create the pool if the outer vg is perfectly - rounded to the GB + thinlvm driver fails to create the pool if the outer vg is rounded to + the GB |
