host node non-operational
Hello, I've installed a engine server and 2 host nodes. After install the 2 nodes I've configured a nfs domain storage in the first node. After few minutes, the second host is down and I dont put it online. The log in the engine show:
Host node2 cannot access the Storage Domain(s) nfsexport_node1 attached to the Data Center Labs. Setting Host state to Non-Operational.
The nfsexport Storage Domain Format is V4, but in the /etc/nfsmount.conf Defaultproto=tcp Defaultvers=3 Nfsvers=3 Also I've added the line NFS4_SUPPORT="no" to /etc/sysconfig/nfs file The node1's iptables rules are: ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT icmp -- anywhere anywhere ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere tcp dpt:54321 ACCEPT tcp -- anywhere anywhere tcp dpt:54322 ACCEPT tcp -- anywhere anywhere tcp dpt:sunrpc ACCEPT udp -- anywhere anywhere udp dpt:sunrpc ACCEPT tcp -- anywhere anywhere tcp dpt:ssh ACCEPT udp -- anywhere anywhere udp dpt:snmp ACCEPT tcp -- anywhere anywhere tcp dpt:websm ACCEPT tcp -- anywhere anywhere tcp dpt:16514 ACCEPT tcp -- anywhere anywhere multiport dports rockwell-csp2 ACCEPT tcp -- anywhere anywhere multiport dports rfb:6923 ACCEPT tcp -- anywhere anywhere multiport dports 49152:49216 ACCEPT tcp -- anywhere anywhere tcp dpt:nfs ACCEPT udp -- anywhere anywhere udp dpt:nfs ACCEPT tcp -- anywhere anywhere tcp dpt:mountd ACCEPT udp -- anywhere anywhere udp dpt:mountd REJECT all -- anywhere anywhere reject-with icmp-host-prohibited And the output of showmount -e command in a terminal of node1 is:
/nfs/data *
But the output of showmount -e node1 in a terminal of node2 is
clnt_create: RPC: Port mapper failure - Unable to receive: errno 113 (No route to host)
Any help? Thanks you in advance. Ángel González

Sounds like a general NFS issue, nothing specific to oVirt. You might want to use normal debugging means - tcpdump, strace, google :-), etc. I think your last error is because you need the portmapper port (111) open. You should see this easily with tcpdump or strace. Also please note that it's not considered a good idea to use one of the hosts as an nfs server, although some people happily do that.

Thanks you in advance.

make sure nfs-lock,nfs-server and rpcbind is running run rpcinfo -p and make sure ports on the firewall are allowed. Looks like you are using firewalld not plain iptables. Host and client firewall settings. make sure you have the following in your /etc/exports file; (rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36) restart services and check showmount -e from client end. Go grab the nfscheck.py file from ovirt's github directory and run it. It will check your nfs mounts. On 16 March 2017 at 18:22, Yedidyah Bar David <didi@redhat.com> wrote:
