Os comandos de montagem NFS ficam suspensos no cliente indefinidamente após a reinicialização do servidor.
Estou executando este comando:mount -t nfs -v 10.17.25.27:/DATA/projects/assets-db/log-apache test
Meu servidor NFS é: 10.17.25.27, o IP do cliente é10.17.25.152
Ativei a depuração de syslog para nfs e vejo estes erros:

Vejo esses tipos de linhas de log repetidas.
Quando executo rpcinfo -p 10.17.25.27no cliente, vejo:

Observe que a montagem com a versão 3 do NFS funciona, mas preciso de recursos da versão 4, portanto não posso fazer o downgrade para esta versão mais antiga do protocolo.
Estou CentOS 7.2com o kernel3.10.0-514.26.2.el7.x86_64

Não descobrimos por que nosso NFS caiu repentinamente e, após a reinicialização, os clientes não conseguiram montar nenhum sistema de arquivos exportado. Tentamos reiniciar todos os servidores, abrir todas as portas entre as máquinas, mas nada funcionou.
No entanto, conseguimos fazê-lo funcionar novamente depois de atualizarmos o kernel de uma versão 3.10.0-514.26.2.el7.x86_64para outra.3.10.0-862.11.6.el7.x86_64
