[ovirt-users] host node non-operational

[Angel R. Gonzalez]

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

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.
