Cannot add host to an existing HA cluster

Hi,

I'm trying to add a new host to an existing cluster with HA enabled, but I am getting the error below:

pool.mergeInto
{
  "sources": [
    "f42c2b0d-9090-8a71-29ea-08860c618e2a"
  ],
  "target": "1242d5b9-c1f7-4fcf-ef1a-21b1967fb6cf",
  "force": true
}
{
  "code": "HA_IS_ENABLED",
  "params": [],
  "call": {
    "method": "pool.join_force",
    "params": [
      "192.168.99.109",
      "root",
      "* obfuscated *"
    ]
  },
  "message": "HA_IS_ENABLED()",
  "name": "XapiError",
  "stack": "XapiError: HA_IS_ENABLED()
    at Function.wrap (/opt/xo/xo-builds/xen-orchestra-202303290507/packages/xen-api/src/_XapiError.js:16:12)
    at /opt/xo/xo-builds/xen-orchestra-202303290507/packages/xen-api/src/transports/json-rpc.js:35:21"
}

Worked fine before enabling HA on the shared storage. HA is working fine as far as I can tell and I do have the cloud icon with the green "very good" on the pool. Not sure what I'm doing wrong.

This is on fully updated XCP-NG servers and XO from source commit 53e0f.

Appreciate any pointers.

Thanks

You need to disable HA, then add the host to the pool, and finally re-add HA.

@olivierlambert Thanks. I suspected that, but thought it was me being dumb and haven't found anything on it

Thanks
