    Hello, I deleted the entire XOA and downloaded fresh image, recreated configuration and blank SR. The issue is gone. I will test some VDI migrations this week. There are is some performance impact and timeouts when creating 100-200 VMs on single 10 TB SR. I use xo-cli vm.create script. See you later

    Hello @codemercenary In theory Xen is NUMA aware (See https://wiki.xenproject.org/wiki/Xen_on_NUMA_Machines) so you would leave memory interleaving option of the BIOS off so that Xen does what it thinks is necessary. But these kinds of settings are very very workload sensitive and in fact it's usually a good idea to just test what works best for you. Regards, Yann

    @MajorP93: Thanks for expressing yourself regarding that, and I'll be transparent about the thinking behind it. Filing those on GitHub isn't me asking anyone to stop using the forum, quite the opposite in fact. The forum is where real conversations happen, and that's valuable in a way a GitHub issue never quite is. But forum threads scroll, get buried, and developers can't easily maintain a stable backlog out of them. GitHub gives the team a place where things don't disappear or get buried. Think of it as belt and suspenders (which I need now that I'm getting old ). The discussion lives here, the tracking lives there. My goal as community manager is to be the relay between the two, so you don't have to worry about it. File things here, talk about them here, and I'll make sure what matters makes it into the right repo. Or at least, that's the plan. Mine.

    Hello, I’m experiencing an issue on an XCP-ng cluster using XOSTOR. Environment: 3-node XCP-ng cluster XOSTOR distributed storage (2x2Tob nvme on each host) XOA for management Management network 1Gb/s Storage Network 10Gb/s MTU 1500 everywhere (no jumbo frames) So during VM migrations, creation, destroy XOA loses connection to my host pool, VMs keep running normally Hosts remain reachable (SSH / HTTPS / ping OK), Connection comes back after some time 30s to 1min. Observations: No significant CPU or RAM saturation No obvious disk latency issues (iostat looks normal) No errors reported on NICs xapi process remains active (no crash or freeze) The problem is intermittent and seems random. i've monitored nic with iftop and i see no bandwith bottleneck et and can see that XOSTOR is using 10gb network only. Has anyone experienced similar behavior with XOSTOR? And how to Fix it ? Thanks in advance for your help.
