Otherwise it is more difficult to understand the problem and do bug triage than needed.</p> <p>The osd code for ZFS code does not count cache hits, misses or accesses. Adding that all cache accesses are misses will still cause test 156 to fail since it expects cache_hits to increase when readcache is enabled.</p> <p>Is this really a blocker? Should it be recharacterized as a feature enhancement to add read/write cache stats to ZFS?</p> <p>If the problem is understood, then all that is needed is to skip the test case for ZFS, checking $(facet_fstype ost1) == ZFS, with a comment explaining why, and referencing this bug. </p> <p>master: <a href="http://review.whamcloud.com/4448" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/4448</a></p> <p>Also created <a href="https://jira.whamcloud.com/browse/LU-2261" title="Add cache stats to zfs osd" class="issue-link" data-issue-key="LU-2261"><del>LU-2261</del></a> enhancement to add caching stats to osd-zfs</p> <p>Landed for 2.4</p> Development Rank 1|hzv9s7: Rank (Obsolete) 5119 Severity
