Anyway, the NFS is still working fine. nlockmgr and NFS are two separate RPC services. So, NFS can work while there might be a problem with nlockmgr. IMO, nlockmgr should respond in this case. > $ rpcinfo -t linux_server nlockmgr > rpcinfo: RPC: Timed out > program 100021 version 0 is not available > > $ rpcinfo -u linux_server nlockmgr > rpcinfo: RPC: Timed out > program 100021 version 0 is not available This is attempting to contact nlockmgr's "version 0" which is not registered (see below). Versions 1, 3, and 4 are registered. Try "rpcinfo -u linux_server nlockmgr 3". > $ rpcinfo -p > program vers proto port > 100000 2 tcp 111 portmapper > 100000 2 udp 111 portmapper > 100024 1 udp 895 status > 100024 1 tcp 898 status > 100011 1 udp 806 rquotad > 100011 2 udp 806 rquotad > 100011 1 tcp 809 rquotad > 100011 2 tcp 809 rquotad > 100003 2 udp 2049 nfs > 100003 3 udp 2049 nfs > 100003 4 udp 2049 nfs > 100021 1 udp 32794 nlockmgr > 100021 3 udp 32794 nlockmgr > 100021 4 udp 32794 nlockmgr > 100003 2 tcp 2049 nfs > 100003 3 tcp 2049 nfs > 100003 4 tcp 2049 nfs > 100021 1 tcp 57164 nlockmgr > 100021 3 tcp 57164 nlockmgr > 100021 4 tcp 57164 nlockmgr > 100005 1 udp 828 mountd > 100005 1 tcp 831 mountd > 100005 2 udp 828 mountd > 100005 2 tcp 831 mountd > 100005 3 udp 828 mountd > 100005 3 tcp 831 mountd nlockmgr is registered, so it must have been started at some point. It's a kernel service, so there's no daemon to die. Do you have some kind of firewall in place that would prevent contacting the NLM service?
