"app.getLicenses is not a function" when I try to add a node to my pool

[bvivi57]

Hi
I already have a pool of three XCP-ng servers. I just purchased two new servers to expand my pool. When I try to add a new node, I get this message :

"app.getLicenses is not a function"
May 05 08:18:58 prdxcpxor501 xo-server[999]: 2026-05-05T06:18:58.175Z xo:api WARN admin@admin.net | pool.mergeInto(...) [16ms] =!> TypeError: app.getLicenses is not a function

I should point out that my new servers are much newer than my existing ones and are built on a completely different hardware platform.

I just updated XO (Xen Orchestra, commit 03380) (I was already having this problem before the update)

Can you help me ?

getLicenses

do you have xostor installed ?

@florent Hi
Yes, but manually, directly from the packages and with manual configuration

I finally managed to do it by switching to the command line interface

xe pool-join master-address=<MASTER-IP> master-username=root master-password=<PASSWORD> force=true

However, my CPUs are too different (AMD Ryzen 9 9955HX 16-Core Processor vs Intel(R) Core(TM) i5-8500T CPU @ 2.10GHz). Even if I force compatibility, I risk losing too many features on my new server. I'm going to create two separate pools.

Thanks for your help

Mixing Intel and AMD is more than losing feature, it's a recipe for crashing your VMs every time you do a live migration.
