Mongodb – Copy files for mongorestore

I’ve got 3 nodes in a replica set.

Each time when performing a mongorestore from the Master, the secondaires go into a RECOVERING state. The oplog cannot keep up. unfortunately I cannot increase the oplog size because lack of disk space.

Now, I want to perform a manual restore by copying the files.

Here is a snippet of the files which I got:

meee@mongo-p01:~$ sudo ls -la /var/lib/mongodb
[sudo] password for meee:

What are the correct steps I should take?

• 1. Reset all mongos by reïnstalling
• 2. Perform a mongorestore on the master
• 3. Right after the restore, stop all mongod
• 4. Copy all local.x and mymongobase.x files to other nodes
• 5. Start mongod on all nodes?

I’m a bit lost here.

• Ensure you have enough disk space!
• Shutdown mongos on all 3 nodes
• From Master node; tar all local* and mymongobase* files
• SCP files to 2 secondaries
• Unpack files in mongo data location (/var/lib/mongodb)
• Start mongod on all nodes

Works for me
