    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

    @acebmxer I already did this several times. I have a running job that takes a backup of the config every night and have the last 7 configs kept. I also did a manual config backup and tried that import as well. Both come up with the same error message on the XOA appliance. Error while importing config. I have both versions of the backup config files. The manual backup which is just one file and the automated config backup which is two files. Any of the files that I try give the same error message that there is an error while importing the config. I also don't see any information in the logs. I have also tried 3 separate times and imported the XOA appliance to start fresh.

    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.
