  • set rebuild flag before creating rebuild_pool_tls, otherwise aggregation
    can progress to higher epoch than rebuild.
  • aggregation doesn't do full scan anymore after rebuild
  • fix a rpt refcount leak in rebuild_tgt_scan_handler()

Steps for the author:

  • Commit message follows the guidelines.
  • Appropriate Features or Test-tag pragmas were used.
  • Appropriate Functional Test Stages were run.
  • At least two positive code reviews including at least one code owner from each category referenced in the PR.
  • Testing is complete. If necessary, forced-landing label added and a reason added in a comment.

After all prior steps are complete:

  • Gatekeeper requested (daos-gatekeeper added as a reviewer).
