#include <iostream>
class Printable {
public:
virtual void print() = 0;
};
class I : public Printable {
private:
std::string *name;

Vagrantfile for LVM testing.

  1. Save this file in your disk and change your PWD to that directory.

  2. Set the environment variable VAGRANT_EXPERIMENTAL to "disks".

export VAGRANT_EXPERIMENTAL=disks
  1. Finally start the vm with vagrant up. You'll definitely see a couple of warning messages like these:-

Exporting livechat messages from db

Livechat rooms and messages both are stored in the same collection, rocketchat_room & rocketchat_message.

To first export the livechat rooms as a json file, use mongoexport like so,

mongoexport --collection=rocketchat_room --db=rocketchat \
  --jsonArray -q='{"t": "l"}' --sort='{_id: 1}' --pretty \
  --jsonFormat=canonical --type=json --out=livechat_rooms.json
