Upgrade ROS 1.0 to 2.0 from AWS EC2 instance.

[FreudGit]

Having a ROS 1.0 installed from amazon EC2 public AMI (see https://realm.io/docs/get-started/installation/deployment/#deploying-the-realm-object-server)

I've followed your upgrade steps.

When I run "ros migrate ..." here are the exact result: ros migrate --from /var/lib/realm/object-server --to /var/lib/realm/object-server-v2/ --copyrealms info: will export /var/lib/realm/object-server/internal_data/auth.realm -> /var/lib/realm/object-server/__admin.json error: (node:31946) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): Error: Unable to open a realm at path ‘/var/lib/realm/object-server/internal_data/auth.realm’. Please use a path where your app has read permissions.

From slack, get reply from user that confirm that she have similar problem. Look like admin.json was installed on another folder than the expected one. (not in /var/lib/realm/object-server/__admin.json)

Thanks for reporting, we are looking into this.

@FreudGit which version of ROS2 is it? Looks like it did not create __admin.json because it failed to open auth.realm earlier.

[FreudGit]

@kvap 2.0.21. (you can easily catch me on #general channel of Slack (Realm))

@FreudGit Can you please post all the commands you followed that led up to this error. Would also need to know the user you are running the commands with and version of node/npm please.

[FreudGit]

node -v = v8.9.0 npm -v = 3.8.3

About the steps, i've followed the steps here: https://realm.io/docs/realm-object-server/latest/#upgrading

1- Installed pre-requisite: sudo apt-get update sudo apt-get install build-essential libssl-dev sudo apt-get install python curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.4/install.sh | bash

// Force current session to know changes or logout and log back in source ~/.profile nvm install --lts npm install -g node-gyp

2- run npm install -g realm-object-server

[ianpward]

What about the migration steps? We also need the exact user you ran all the commands with

[FreudGit]

Migration: ros migrate --from /var/lib/realm/object-server --to /var/lib/realm/object-server-v2/ --copyrealms

User: main user\administrator.

@FreudGit Thanks - can you list all files in each folder object-server and object-server-v2 with permissions and ownership?

Judging from the slack messages: https://realm-public.slack.com/archives/C03V755FS/p1511012231000021

My best guess is that you installed npm, nvm, or ros with different linux user and then attempted to run ros migrate with a user that did not have permissions. You should not need to chmod anything if the user is consistent. Can you please uninstall everything and then re-install and re-run the migration?

If you run into the same issue please post the exact commands with user for each step, for example:

[centos@data-adapter-server ~]# sudo npm install realm

[kvap]

@FreudGit make sure that you (the user running ros migrate) have read-write access to everything inside /var/lib/realm/object-server.
