As montagens NFS recentemente foram desmontadas automaticamente. Quando verifiquei, o status do serviço NFS estava em execução.
[root@hsluasrepo]# service nfs status
rpc.svcgssd is stopped
rpc.mountd (pid 4083) is running...
nfsd (pid 4148 4147 4146 4145 4144 4143 4142 4141) is running...

[root@hsluasrepo]# service rpcbind status
rpcbind (pid 4203) is running...
[root@hsluasrepo common]# rpcinfo -p 10.80.3.154

100000 3 udp 111 portmapper
100000 2 udp 111 portmapper
Mas a showmount
saída estava mostrando um erro.
[root@hsluasrepo ]# showmount -e 10.80.3.154
clnt_create: RPC: Program not registered
Após reiniciar o serviço NFS, a showmount
saída exibia a lista de exportação do servidor NFS.
Alguém pode me dizer a causa raiz desse problema e como evitar esse problema no futuro?
