    @carloum70 Are all your hosts properly time sychronized to NTP or chronyc? Check each host for offsets. They need to be really close in time with each other. And what HA heartbeat client setup are you using? As long as you have a quorum, HA should continue to work fine. WHen you get down to two hosts and one cannot communicate with the other is when things get critical (unless running HA-Lizard on a two-host pool).

    I ran into the same problem with DR replicas. Ignoring VMs by tag would solve the problem, but so would excluding the ip address information.

    @andrewperry yes, we replicate TrueNAS to a "standby" TrueNAS using zpool / truenas replication. Our current policy is hourly. We then (plan) to do Incremental replication of all VM's to a standby TrueNAS over weekends giving a 3 possible methods for recovery. Currently we're running into a major drawback with VM's on TrueNAS over NFS (specifically VM's that rely on fast storage such as databases and recordings). We did not anticipate such a huge drop in performance having VHD files over NFS. We're reaching out to XCP to ask them to give us some advice as it could likely be in part due to customization we can make.

    @wildones It's good that the XCP hosts can reach each other, but that's not enough. XOA needs to reach all the hosts too. You may want to use an XO proxy to manage remote locations. Please read the XO proxy guide.

    @BenjiReis I tried to fill in the IP address with brackets, but then the discovery of the NFS shares fails. With regular SRs, it works fine without using brackets.

    In fact it's already possible In your replication job: Edit the schedule, check "Health check" box. Target the same SR than your VM are replicated too And voila!

    @stormi So I looked into the code of the ISOSR and there is a parameter for the version in the device-config. The parameter is vers but it can only be V1 or V3. And if it can't connect with V3, it will also try with V1.

    Hello @Andrew, thanks for your question! First off, I haven't tested Deno or Node with Xen-Orchestra yet. Changing the Node version can sometimes introduce bugs—some of which may be subtle. For that reason, I’d prefer not to venture into this unless it truly proves to be worth the effort. Secondly, in my experience, benchmarks don’t always translate into meaningful results in complex applications. That said, we are keeping an eye on alternative engines, both in terms of performance and the new features they offer. If we determine that the benefits are significant, we’d definitely consider migrating. Additionally, if any users want to experiment with Deno or Bun, they’re welcome to start dedicated threads on the forum to collaborate. We’d be happy to review and merge compatibility PRs as long as they don’t break Node and aren’t overly complex.

    @Danp So I had a problem with ldap, I read older article that mentioned doing this sudo npm install --global xo-server-auth-ldap which coincidently fixed ldap but that is when I noticed sync option were gone. This is just a POC and has noting running, so I will destroy and build new xoa. Thanks for help.

    @tuxpowered said in Rolling Pool Update - host took too long to restart: When the first note reboots (the master), I can see that the system is back up in 5-8 min. If I go in to XO > Settings > Servers and click the Enable/Disable status button to reconnect it pops right up. Again, does not resume migrating the other nodes. That is what I am seeing also, logged here https://xcp-ng.org/forum/topic/9683/rolling-pool-update-incomplete

    The easiest way to guarantee it is to depend on a local resource (local SR or ISO).

    If you proxy (or reverse proxy) any stuff, yes, you need to have a fixed address for the proxy.

    Yes, that's the issue, the max vCPU in Advanced tab. It's probably at 42 while you only have 32 physical CPUs. Therefore, the VM won't boot. See an example screenshot: [image: 8728f260-893b-4601-b8b2-43b39b9d6806-image.png]

    Hi, We offer air gap services to get you pre-bound XOA without the need for any Internet connection Otherwise, the workflow you used works too (configure XOA with a connected env and then export it). See https://xen-orchestra.com/docs/airgap.html for more details. Also, you can use our airgap deploy script in here: https://xen-orchestra.com/blog/xen-orchestra-5-95/#️-air-gap-features
