[OPIK-7332] [HELM][DOCS] fix: two-phase HA guidance for multi-replica ClickHouse installs
-
docs(self-host): format two-phase install as Fern Steps components
Address PR review (Baz): the migrate-then-scale procedure was raw Markdown
1./2./3. lists; wrap it in Fern / per the write-docs convention.
Applied to both the scaling and troubleshooting pages across the v1 and v2 docs.- test(helm): cover explicit single-replica NOTES case (PR review)
Address PR review (JetoPistola): add an explicit
clickhouse.replicasCount: 1
test for the conditional's lower boundary (robust to a future default change),
and keep the no-override test — renamed to "default replica count" — as a canary
that the shipped default stays single-replica and keeps the banner off.- docs(self-host): clarify configurable DB name and greenfield ZK recovery (PR review)
Address PR review (Baz):
- Note that
opikis the default analytics database name
(ANALYTICS_DB_DATABASE_NAME) and may be overridden, mirroring the existing
ZooKeeper-recovery note on the same page. - Reword the REPLICA_ALREADY_EXISTS warning: a fresh install has no data to
preserve, so recovery only needs the orphaned ZooKeeper paths cleared — the
full replica-restore rebuild in the linked section is for existing data and
isn't needed here (avoids pointing greenfield operators at a destructive
data-restoration procedure).
