हाल ही में NFS माउंट स्वचालित रूप से अन-माउंटेड हो गया है। जब मैंने जाँच की, तो NFS सेवा की स्थिति को चालू दिखाया गया था।
[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
लेकिन showmount
आउटपुट में त्रुटि दिखाई दे रही थी।
[root@hsluasrepo ]# showmount -e 10.80.3.154
clnt_create: RPC: Program not registered
NFS सेवा को पुनरारंभ करने के बाद, showmount
आउटपुट ने NFS सर्वर की निर्यात सूची प्रदर्शित की।
क्या कोई मुझे इस मुद्दे का मूल कारण बता सकता है और भविष्य में इस समस्या से कैसे बचा जा सकता है?
