NFS mounts baru-baru ini secara otomatis dibatalkan. Ketika saya memeriksa, status layanan NFS yang ditunjukkan sedang berjalan.
[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...
rpc.rquotad (pid 4079) is running...
[root@hsluasrepo]# service rpcbind status
rpcbind (pid 4203) is running...
[root@hsluasrepo common]# rpcinfo -p 10.80.3.154
program vers proto port service

100000 4 udp 111 portmapper
100000 3 udp 111 portmapper
100000 2 udp 111 portmapper
Tetapi showmount
output menunjukkan kesalahan.
[root@hsluasrepo ]# showmount -e 10.80.3.154
clnt_create: RPC: Program not registered
Setelah memulai kembali layanan NFS, showmount
output menampilkan daftar ekspor server NFS.
Adakah yang bisa memberitahu saya akar penyebab masalah ini dan Bagaimana cara menghindari masalah ini di masa depan?
