Subject: test/store_test: fix deferred writing test cases
X-Git-Tag: v19.3.0~304^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=fd3be76ecc2c6b1f436cda19ba961f8f45014b02;p=ceph-ci.git

test/store_test: fix deferred writing test cases

When bitmap allocator is in use different space fragmentation and
allocation strategy cause blob fragmentation. Which in turn impacts the
decision on deferred write applicability.

Fixing by using standalone DB volume to reduce main device space fragmentation.
