Hi. Actually, that command should work. The server should respond with an RPC error indicating which versions of the nlockmgr protocol are supported and then rpcinfo will ping each of them. ps -----Original Message----- From: linux-nfs-owner@xxxxxxxxxxxxxxx [mailto:linux-nfs-owner@xxxxxxxxxxxxxxx] On Behalf Of Chuck Lever Sent: Friday, January 14, 2011 10:18 AM To: hce Cc: Linux NFS Mailing List Subject: Re: mac error On Jan 13, 2011, at 11:01 PM, hce wrote: > Thanks for your response.

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? Does "linux_server" resolve to the IP address you expect it to? -- Chuck Lever chuck[dot]lever[at]oracle[dot]com -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
