Subject: Fix free_capacity reporting in SolidFire driver
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=cfac9c7945f3cd5d39b7f6bd8950427a144b889d;p=openstack-build%2Fcinder-build.git

Fix free_capacity reporting in SolidFire driver

The SolidFire driver reports capacity info in bytes, the
capabilities update reports available_GB.  Sadly we neglected
to convert the bytes to gigibytes here which made for a VERY
large backend and caused things like capacity filtering to not
work correctly.

This patch just adds conversion to GiB when reporting capabilities.
