Description of problem: A recent rook issue report suggests that under various circumstances (dynamic bucket index reshard event) the swift healthcheck can be delayed, causing liveness checks to fail. https://github.com/rook/rook/issues/6304 Since the swift healthcheck has minimal overhead and generates no cluster traffic, this is unexpected, but may be due to lack of request prioritization.
Please specify the severity of this bug. Severity is defined here: https://bugzilla.redhat.com/page.cgi?id=fields.html#bug_severity.
In testing on a vstart.sh cluster (HDDs) while resharding 10M objects bucket checking the watchdog http GET operation latency to the /swift/healthcheck url via curl: curl -sv -D - "http://127.0.0.1:8000/swift/healthcheck" the latency is not affected by ongoing resharding. Added a reequest for more information to the github issue.
