Merge Risk: 🔵 Low · up to The new backing-store replace command looks mergeable. However, the end-to-end test's readiness wait checks the NooBaa system status rather than the new backing store. The test may therefore start the replacement before the store is ready and fail intermittently. Fixing the wait helper is a small follow-up. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

Full details: Description checkExplanation The description explains the problem, intended workflow, changes, and tests, but it conflicts with the supplied change summary. It says the command uses existing tier and account APIs and needs no noobaa-core changes, while the summary says it calls the new safe_replace_pool RPC. It also omits several template headings and checkboxes. Resolution Update the description to accurately document the safe_replace_pool RPC and its noobaa-core dependency.

Is this replace work on all the buckets at once? So if there are 100 buckets and we are doing migration on those buckets will it create any issue?
There was a problem hiding this comment.
Yes, it updates all affected tiers in a single system_store.make_changes() call — one atomic bulk DB write. Even with 100 buckets, it's just updating tier documents, not moving data. The heavy lifting (actual data replication in migration mode) is handled by the existing mirror_writer background worker which processes buckets independently. So the replace call itself is fast regardless of bucket count.

I think, we should also provide buckets specific replace too,

Agreed, may be we can add --bucket-name flag (mandatory)
There was a problem hiding this comment.
I thought about this, but I don’t think it works cleanly because tiers can be shared by multiple buckets through tiering policies.
For example, if we replace a pool in a tier for Bucket A, Bucket B could also be affected if both buckets use the same tier. So adding per-bucket filtering could be misleading because users may think they are changing only one bucket when they could actually impact others.
Also, the main reason this bug exists (DFBUGS-6233) is that there was no way to update all non-OBC buckets at once. Making --bucket-name mandatory would mean users have to manually provide every bucket, which is exactly the problem we are trying to solve.
If there is a real customer need to filter by bucket, we can add it as an optional flag later if there's a concrete use case. But we should design it carefully because of the shared-tier behavior.

Are we really starting the migration here? Is it done by background worker?
There was a problem hiding this comment.
We're not starting any new process. The RPC just adds the new pool as a separate mirror group in each tier and sets data_placement: MIRROR. The existing mirror_writer background service (in src/server/bg_services/mirror_writer.js) already runs continuously — it detects MIRROR tiers and copies chunks between mirror groups automatically. So we're just configuring tiers in a way the existing worker picks up.

why are we giving these steps in response?
There was a problem hiding this comment.
Because the replace workflow has multiple steps — especially in migration mode where the user needs to wait for replication, finalize, set manualDefaultBackingStore, and then delete the old backing store. Printing the exact oc patch and oc delete commands saves the user from looking them up. Without these, the user would need to check external docs to figure out what to do next. It's a one-time print per invocation, not noisy. If you say i will remove them.

not sure customer is familier with Tiers, Its better to return bucket name too
There was a problem hiding this comment.
Fair point. Right now the RPC reply only returns tier and account counts — adding bucket names would require traversing tiering policies → buckets in the core RPC, which adds complexity. For this first version, the tier/account counts are enough for an admin to confirm the operation worked. We can enhance the reply to include affected bucket names in a follow-up.

Can you explain this how --mirror works? Do we need to run the replace command twice here?
There was a problem hiding this comment.
Yes, it's two steps:
noobaa backingstore replace old new --migrate adds new as a mirror alongside old. The background mirror_writer then copies existing data from old to new automatically.
noobaa backingstore replace old new (without --migrate) removes old and keeps only new.
The two-step approach makes sure data is fully replicated before we cut over. If you don't care about existing data (e.g., empty buckets), you can skip step 1 and just run the direct replace.
There was a problem hiding this comment.
Why we are not doing it in one step?
Are we manually checking whether the mirroring is done or not. Will step 2 check this part and remove old one after mirroring is done.
There was a problem hiding this comment.
Two steps because the user needs to decide when replication is done we can't automate that judgment. Step 1 sets up mirroring then the mirror_writer starts copying data in the background. The user checks replication progress and decides when to finalize. Step 2 (finalize) just swaps the pools it doesn't check replication status, it trusts the user has verified it. Making it one step would risk data loss if we cut over before all data is replicated. The two-step approach is the safe path.

Do we have any tracker or something to verify the mirroring status?

Not a dedicated one today. The user can check noobaa bucket status to see the mirror configuration is in place, and the mirror_writer logs progress to the NooBaa server logs.

Can you please share an example of how bucket status would show mirror status (screenshot may be)?
And now we can move to step 2.
There was a problem hiding this comment.
After --migrate, noobaa bucket status will show the tier with both pools listed under MIRROR placement. The tier mode reflects the mirror configuration. Once mirror_writer finishes copying all chunks, both pools show OPTIMAL status. At that point you run the finalize step.
No single '% complete' indicator today — the user checks that both pools are OPTIMAL in bucket status. We can add a progress indicator as a follow-up.

why we need this step?
There was a problem hiding this comment.
The --migrate step is optional — it's only needed when buckets have existing data on the old backing store that you don't want to lose. It adds the new pool as a mirror so the mirror_writer background service copies existing objects to the new pool before you cut over.
If your buckets are empty or you don't care about existing data, skip --migrate entirely and just run noobaa backingstore replace directly. That does the swap in one step.
The two-step flow exists for production scenarios where losing existing data is not acceptable.

Use existing per-bucket APIs (update_tier, read_system, update_account_s3_access) to replace backing store references across all bucket tiers and account defaults. This addresses DFBUGS-6233 where replacing the default backing store only propagated to OBC-created buckets via BucketClass, leaving CLI/S3/UI-created buckets on the old pool. The replace command: - Calls ReadSystemAPI once to get all buckets, tiers, and accounts - Builds a tier lookup map and iterates bucket tiers for old pool refs - Calls update_tier per-tier to swap old pool with new pool - Updates account default_resource for affected accounts - Supports --migrate flag for mirroring data before final switchover No noobaa-core changes required — uses existing tier_api and account_api.

Problem
DFBUGS-6233
When replacing the default backing store on an active system, CLI/UI/S3-created
buckets remain tied to the old pool because BucketClass updates only propagate
to OBC-created buckets. There is no supported CLI command to safely detach the
old backing store from all buckets and accounts.
Solution
Add a new
noobaa backingstore replaceCLI command that uses existing NooBaaAPIs to replace backing store references across all bucket tiers and account
defaults. A single
ReadSystemAPIcall loads all buckets, tiers, and accounts,then
tier_api.update_tierandaccount_api.update_account_s3_accessperformthe targeted updates.
No noobaa-core changes required — this uses only existing RPCs.
