=== memcached 1->3 LIVE scale-up, dc0, 2026-08-06T08:04:32Z (BUNDLEFIX-055; operator-approved) ===
Command (dc0 rack, D-138): juju add-unit memcached -n 2 --to lxd:1,lxd:2 -m vr1-dc0  (exit 0)

CONVERGED 3/3 active/idle (one per control node):
  memcached/0*  active idle  0/lxd/9   10.12.12.115  11211/tcp  Unit is ready and clustered
  memcached/1   active idle  1/lxd/22  10.12.12.166  11211/tcp  Unit is ready and clustered
  memcached/2   active idle  2/lxd/20  10.12.12.165  11211/tcp  Unit is ready and clustered
memcached install was clean (no F5 apt-wedge; tiny package).

CONSUMER VERIFY (D-121 verify-at-deploy):
  nova-cloud-controller/leader nova.conf: memcache_servers = 10.12.12.115:11211,10.12.12.166:11211,10.12.12.165:11211  -> ALL 3 servers, OK
  designate/leader designate.conf: backend_url = memcached://10.12.12.115:11211  -> ONE server only.
    designate is workload-BLOCKED (nameservers/Stage-7), so its config is pre-activation and not
    final; whether tooz coordination picks up all 3 is a Stage-7 designate-activation verify, not
    a memcached scale-up defect. RECORDED, not fixed (hard rule 1).
