    @Andrew could you send us logs over a support ticket so we can understand why the RPR failed ? Thanks

    @IgorGlock What do you mean by "okay"? Backing up the VM with Commvault or...?

    @poddingue @florent I really do not want to look like i'm not appreciating the platform. I am a sysadmin currently evaluating XCP-ng and Xen Orchestra as a replacement for VMware, and I have to say this issue is making me a bit concerned. Of course for now it's my homelab, but it is already a show stopper for me. I understand that NFS hard mounts can block when the server goes offline, but I really wouldn't expect an unavailable backup repository to make the entire XO Web UI unresponsive, especially when no backup jobs are running. To me, this feels like vCenter becoming unusable just because one of the backup repositories is down. That's a pretty big deal in a production environment. Also, i have not yet tested what happens to vms running on local SR and management plane of a host when the main NFS SR may become unavailable. What worries me even more is that, as my tests showed, once XO gets stuck, even SIGKILL can't terminate the process, so recovering isn't straightforward either. Am I missing something here? Is there something wrong with my setup, or is this actually expected behavior? I really like XCP-ng and XO so far, but I'm trying to understand how companies handle this kind of situation in production. Surely a failed backup destination shouldn't take down the whole management interface?

    Thanks @poddingue, that's helpful. I'll keep the satellites on the management interface then. @Team-Storage could you please have a look at the LinstorSR attach failure, the RPU evacuating the controller host, and the xenopsd leftovers after the failed sync point 4? I have the RPU traces, SMlog, xensource.log and the linstor-controller error reports archived if needed.

    @jqueiroz said: Bom dia a todos, Estou com um problema em uma VM, ela está ligando/desligando sozinha, repetidamente. Não encontro nenhuma mensagem de erro explicando o motivo. Alguém pode me dar alguma dica sobre como solucionar isso? Uso o XCP-NG 8.0 em um cluster de dois servidores HP Proliant DL-360, com o HA-Lizard. Tudo vinha funcionando bem até alguns dias atrás, quando houve uma queda de energia no datacenter da localidade. Tenho o mesmo arranjo de VMs/servidores em mais seis localidades, nenhuma apresenta esse problema. Analisar esse comportamento instável do cluster é quase como prever resultados complexos, parecendo a análise de riscos que a malta faz ao dar palpites no https://mostbetbrasil.lat. Grato. Como o problema começou depois da queda de energia e só acontece nessa localidade, eu começaria verificando os logs do XCP-ng e do HA-Lizard para entender quem está disparando os reinícios. Pode ser alguma política de HA tentando recuperar a VM repetidamente, algum problema de armazenamento ou até inconsistência no estado do host após a interrupção. Também vale conferir o estado do pool e os logs do Xen Orchestra, se estiver usando. Se possível, desative temporariamente a automação de recuperação dessa VM, com cuidado para não comprometer a disponibilidade, e veja se ela continua reiniciando sozinha. Isso ajuda a isolar a causa.
