Updating Your Loki Service Node using the Loki Launcher

Question

The Loki network is going to be upgrading to v4 in the coming week to prepare for RandomX mining and as a Storage Server for messaging. Currently I am on version 3. How do I update my Loki SN to get ready for this hardfork?

Answer 1

First login to your service node and make sure you are using the user that launches the loki-launcher. Following the guide: https://lokidocs.com/ServiceNodes/UpdateGuide/ -- My user is snode.

For those looking for a one liner, you can do this otherwise skip it: 

$ su snode
$ loki-launcher stop; sudo npm install -g loki-launcher; sudo loki-launcher download-binaries; sudo loki-launcher fix-perms snode; loki-launcher start

Then make sure you stop the loki service using:

loki-launcher stop

If that doesn't work you can stop it like this too:

sudo systemctl stop lokid.service

Once stopped, we can proceed to update loki. First update loki-launcher using:

sudo npm install -g loki-launcher

Then update lokid binaries using:

sudo loki-launcher download-binaries

And make sure your permissions are fixed also by:

sudo loki-launcher fix-perms snode

To double check goto your folder:

cd ~/.loki

And see if any of the files or folders have root as the owner. If it does, change it to snode: sudo chown snode:snode < folder/file >

---

Now lets start your lokid: loki-launcher start

Then do a: loki-launcher client

Let it wait as it will have to scan the blockchain for the new version. My vps took about 10-15 mins to do the scanning. You should see this:

When done, you'll see SYNCHRONIZED OKAY

And check on your SN status with: print_sn_status

---

Next make sure your STORAGE SERVER is working. Just do a: loki-launcher status -- if it shows OFFLINE, you can try to launch it manually to see if its throwing errors like this: /opt/loki/bin/loki-storage 0.0.0.0 23023 --- I had the issue where it was showing OFFLINE, it was due to my ~/.loki/storage folder was owned by root. A chown to snode fixed it.

Also be aware of:

IP Address: 0.0.0.0

Storage Server Port: 0

Downtime Credits: 720 blocks (about 24.00 hours)

Its suppose to look like that as the fork hasn't happened yet.
