Pitr restore working different way in two ways

[kyeongjun.me]

Description:

I’m testing pitr backup and restore in percona mongodb operator. There are two ways.

1. using psmdb-backup crd - in backupName

apiVersion: psmdb.percona.com/v1
kind: PerconaServerMongoDBRestore
metadata:
  name: restore-phy2
spec:
  clusterName: mongodb-test-psmdb-db
  backupName: cron-mongodb-test-psm-20240109065000-qskww
  pitr:
    type: date
    date: 2024-01-09 06:52:41

2. using s3 source in new kubernetes environment

apiVersion: psmdb.percona.com/v1
kind: PerconaServerMongoDBRestore
metadata:
  name: restore-pitr-source
spec:
  clusterName: mongodb-test-psmdb-db
  pitr:
    type: date
    date: 2024-01-09 06:52:41
  storageName: s3-percona-mongodb-backup
  backupSource:
    destination: s3://<bucket name>/<prefix>/2024-01-09T06:50:21Z

In first way, backup-agent container’s log is below.

2024-01-09T08:43:19.000+0000 I got command restore [name: 2024-01-09T08:43:18.183792383Z, snapshot: 2024-01-09T06:50:21Z point-in-time: <1704783161,0>] <ts: 1704789798>

In second way, backup-agent container’s log is below.

2024-01-09T08:41:11.000+0000 I got command restore [name: 2024-01-09T08:41:10.846677691Z, snapshot: 2024-01-09T06:50:21Z point-in-time: <1704783161,0>] <ts: 1704789670>

The difference is, second backup-agent fall in to stuck status. Anymore log is sdtouted and no action…
In second way, container killed immediately. (The timestamp is strange)

2024-01-09T08:43:19.000+0000 E [restore/2024-01-09T08:43:18.183792383Z] restore: check mongod binary: run: exec: "mongod": executable file not found in $PATH. stderr:
2024/01/09 08:44:39 [entrypoint] got terminated, shutting down

I’m testing in various way in other options.
Anybody here to advise to me?
Thank you.

@kyeongjun.me how does kubectl get psmdb-restore -o yaml look like?
is there any error there?

[kyeongjun.me]

@Sergey_Pronin Thank you for your reply!! I re tried pitr restore. The result is below.
just get psmdb-restore result is below. - requested

@Sergey_Pronin Any news on this topic ? By the way, does Restore backup to a new Kubernetes-based environment - Percona Operator for MongoDB work at all with Percona MongoDb Operator 1.15.0 ? Or should we wait for 1.16.0 ?

[Sergey_Pronin]

Hey folks.

I’m trying to reproduce it. Will update you later today.

[dxzio]

@Sergey_Pronin Do you have an update or still need more information ?

[Sergey_Pronin]

No information needed.
Do you use sharding in your cluster?

We were able to reproduce the problem, but with slightly different error. Also it is reproducible for clusters with sharding enabled (even if it is just one shard). We are digging deeper now.

[dxzio]

Yes, i have sharding cluster.

[kyeongjun.me]

I tested in shared cluster with only 1 shard

My values.yaml of psmdb-db is below.

# Default values for psmdb-cluster.

Hi @Sergey_Pronin, should i create a bug ticket or have you already done it ?

[Sergey_Pronin]

I have created one: [K8SPSMDB-1036] - Percona JIRA
