Subject: Limit ram and disk used by ceph backup tests
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=b1c5d16055b3aad6d7ae6bb6df90c645c3897075;p=openstack-build%2Fcinder-build.git

Limit ram and disk used by ceph backup tests

The test_discard_bytes test in
cinder/tests/test_backup_ceph.py uses a lot of
ram and disk space since it tests the ceph driver with
the default chunk size of 128Mi. This patch lowers it
to use 1024 bytes instead.

Closes-bug: #1417293
