Once started you need to initialises the replicaset:
mongo --eval "printjson(rs.initiate())"
===Dump and restore===
Samples - YMMV.
Quick little script to dump the Rocket.Chat collection:
#!bin/bash
echo "Dump with Users/Roles"
mongodump --dumpDbUsersAndRoles -d rocketchat -o /root/backup/rocketchatmongo
echo "dump all"
mongodump -d rocketchat -o /root/backup/rocketchatmongo-all
And to restore:
mongorestore /root/backup/rocketchatmongo-all
Do not restore between versions.
If you export from a version eg 4.0 then restore to that version. Do not try and restore 4.0 to 4.2 or higher.
Then change your repo, and then upgrade mongo.
