Implement asymmetric pool create for system-membership excluded ranks:

  • keep excluded/admin-excluded ranks in pool map and initialize their targets as DOWNOUT
  • plumb downout_ranks through PoolCreate
  • run MGMT_TGT_CREATE only on active ranks (targets - downout_ranks)
  • use active-rank count for pool size split / svc-replica limits

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).
