Greetings,
I've spend a couple of hours today on trying to get an SBC Cluster working with two Raspberry Pi 4's (4GB) but to no avail..
Is it even possible to have an SBC Cluster on Raspbian Buster (v10)?
As I see conflicting data in the guides:
• "be two (2) PCs or Raspberry Pis with the same Debian or Raspbian (9/Stretch) Linux version and updates."
• "A Raspberry PI 4 B4 or B8"
-> I tried installing Raspbian Strecht Lite on RPi 4 but it can't boot with it, as it requires a newer OS.
I have tried several things by following these topics:
- https://www.3cx.com/docs/installing-pbx-raspberry-pi/
- https://www.3cx.com/docs/sbc-high-availability-cluster/
A single SBC works perfectly fine, but when I configure SBC 1 as the first node and then run the script on the SBC 2, it just doesn't work.
The log that SBC 2 shows upon finishing the configuration show both IP's are [online] but when I do crm status or crm_mon it says there is no active cluster / waiting for it to get online.
(I don't have the exact logs in front of me, the Raspberry Pi's are in another location at the moment)
The 3CX management console shows the Virtual IP in the details of the SBC entry and the phones can connect fine.
However when I turn off SBC 1, phones can't connect anymore. SBC 2 does not take over.
I first did an installation by updating/upgrading everything on the Raspbian and tried it again without the updates, but it made no difference.
I've done all the things that the guides speak of:
• Set the same timezone
• changed hostname (& password)
• set them to a fixed IP (.253 & .254) on the same LAN
• ran the SBC script and used the same Authentication ID from Management console
wget https://downloads-global.3cx.com/downloads/misc/d10pi.zip; sudo bash d10pi.zip
• Installed the cluster from the last question from that script.
• Selected the correct "first" or "second" node.
• Entered the IP of the other SBC when required
• Added the Virtual floating IP and is not in use elsewhere on the network (.248)
• Added the default gateway & 8.8.8.8 as ping resource
• the summary shows correct data
• Did the same thing on the SBC 2 but of course by choosing it's the second node, entered the IP of the first SBC when required, used the same virtual floating ip, ...
• the summary shows correct data
If it's at all possible to install, I can get and post the logs, but I'll have to do another installation from scratch (reinstall raspbian etc) as they are currently installed as two seperate SBC's but the secondary/back-up serveraddress of our phones don't seem to work too well for this..
Thank you!
