Hello Ivan, Just a follow-up on this ticket. Mongod-failure-after-restore - #2 by Ivan_Groenewold I attempted to perform a restore on the secondary instance despite the Mongo service failure. The PBM status has been mentioned above. Could you please share the documentation or Linux commands for p…

[image] hemanth: However, when we attempt to restore, the mongod service fails even though the restoration process is reported as successful. After this, all three mongod services fail. I am trying to restore the data only on a secondary server. Thanks for the explanation and more context - t…

I believe you need to follow the initial sync procedure as @Ivan_Groenewold mentioned. Here’s the guide: [image] Resync a Member of a Self-Managed Replica Set - Database Manual - MongoDB Docs Resync a stale replica set member by removing its data and performing an initial sync or by co…

Hi radoslaw.szulgo We have tried the initial sync procedure and provided the output Mongod-failure-after-restore . We are also using PBM for backup and restore operations.

can you please provide some more information on what doesn’t work for you? Any error messages? Without that it’s really hard to help in your case.

We are using a cloud infrastructure running on Ubuntu with three servers: one primary and two secondary. We are running Percona Backup for MongoDB (PBM) version v2.10.

We are taking incremental backups through S3. When we initiate the backup from the secondary server, it works successfully. However, when we try to restore the data to the secondary server, all mongod processes on both the primary and secondary servers fail. Additionally, we are unable to perform th…

Right, you cannot do “backup” for initial-sync… but why would you? Can we take one step back and clarify what’s the use case you’re trying to implement? Why do you want to restore just 1 out of 3 nodes? Something is broken or that’s a “recovery” procedure for any node? Something else?

Right now, we are performing a POC with the goal of taking a full data backup using PBM. After that, we plan to enable incremental PITR to take hourly backups. During the POC, we successfully pushed the data to S3 through PBM. However, when we tried to restore the same data after enabling PITR, the …

Can you provide logs from at least 1 server? What error is shown there?

The procedure I followed for the restore was: I removed the MongoDB data directory, but after doing so the mongod service failed to start. I started it again and then executed the restore command pbm restore 2025-10-30T07:01:38Z. A few minutes later, the mongod service went inactive. I’ve also attac…
