Hello, ### Description I use RC with your provided docker-compose.yml: [https://github.com/RocketChat/Rocket.Chat/blob/develop/docker-compose.yml](https://github.com/RocketChat/Rocket.Chat/blob/develop/docker-compose.yml) I wanted to migrate to another dedicated server, so I just copy/paste my /docker/rocketchat folder with data and docker-compose but I got a Mongo error when running it. My docker-compose: version: ‘2’ ``` services: rocketchat: image: rocketchat/rocket.chat:latest command: > bash -c "for i in `seq 1 30`; do node main.js && s=$$? && break || s=$$?; echo \"Tried $$i times. Waiting 5 secs...\"; sleep 5; done; (exit $$s)" restart: always volumes: - /home/aerya/docker/rocketchatUAC/chat/uploads:/app/uploads environment: - PORT=3000 - ROOT_URL=http://0.0.0.0:3000 - MONGO_URL=mongodb://mongo:27017/rocketchat - MONGO_OPLOG_URL=mongodb://mongo:27017/local - MAIL_URL=xxx depends_on: - mongo ports: - 3000:3000 labels: - com.centurylinklabs.watchtower.enable=true mongo: image: mongo:4.0 restart: always volumes: - /home/aerya/docker/rocketchatUAC/data/db:/data/db command: mongod --smallfiles --oplogSize 128 --replSet rs0 --storageEngine=mmapv1 mongo-init-replica: image: mongo:4.0 command: > bash -c "for i in `seq 1 30`; do mongo mongo/rocketchat --eval \" rs.initiate({ _id: 'rs0', members: [{ _id: 0, host: 'localhost:27017' }]})\" && s=$$? && break || s=$$?; echo \"Tried $$i times. Waiting 5 secs...\"; sleep 5; done; (exit $$s)" depends_on: - mongo ``` Mongo logs: [https://pastebin.com/f1UsLHWt](https://pastebin.com/f1UsLHWt) I don’t understand this error because everything is exactly the same except IPv4/6 which doesn’t matter here. ### Server Setup Information Not related ---

Hmmm. So I think that somewhere we’re probably missing some info. We have this: > 021-05-29T08:18:30.563+0000 I REPL [initandlisten] Recovering from an unstable checkpoint (top of oplog: { ts: Timestamp(1622273765, 2), t: 15 }, appliedThrough: { ts: Timestamp(1622273765, 2), t: 15 }) > 2021-05-29T08:18:30.563+0000 I REPL [initandlisten] Starting recovery oplog application at the appliedThrough: { ts: Timestamp(1622273765, 2), t: 15 }, through the top of the oplog: { ts: Timestamp(1622273765, 2), t: 15 } > 2021-05-29T08:18:30.563+0000 I REPL [initandlisten] No oplog entries to apply for recovery.

Thanks for last advice. I used mongodump/restore to make it through. It’s not really solved but I could go on. ---

Hope you didn’t misunderstand me meaning _it’s not really solved_. I was talking about the cp/rsync/mv that should have worked “out of the box”. I’m glad to be able to use RC again on my new server. ---

Ah OK. The copy issue is down to your OS/docker, not Rocket. Glad it is working.
