Hi, this was an extract from the old logs, before Soumya's suggestion of changing the rquota port in the conf file. The new logs are attached (ganesha-20150611.log.gz) as well as the gstack of the ganesha process while I was executing the hanging showmount (ganesha-20150611.gstack.gz).

Before exporting any volume the log shows no error, even when I do a showmount (the log is attached, ganesha.log.gz). If I do the same after exporting a volume nfs-ganesha does not even start, complaining for not being able to bind the IPv6 ruota socket, but in fact there is nothing listening on IPv6, so it should not happen: > > >>> > > >>> tcp6 0 0 :::111 :::* LISTEN 7433/rpcbind > > >>> tcp6 0 0 :::2224 :::* LISTEN 9054/ruby > > >>> tcp6 0 0 :::22 :::* LISTEN 1248/sshd > > >>> udp6 0 0 :::111 :::* 7433/rpcbind > > >>> udp6 0 0 fe80::8c2:27ff:fef2:123 :::* 31238/ntpd > > >>> udp6 0 0 fe80::230:48ff:fed2:123 :::* 31238/ntpd > > >>> udp6 0 0 fe80::230:48ff:fed2:123 :::* 31238/ntpd > > >>> udp6 0 0 fe80::230:48ff:fed2:123 :::* 31238/ntpd > > >>> udp6 0 0 ::1:123 :::* 31238/ntpd > > >>> udp6 0 0 fe80::5484:7aff:fef:123 :::* 31238/ntpd > > >>> udp6 0 0 :::123 :::* 31238/ntpd > > >>> udp6 0 0 :::824 :::* 7433/rpcbind > > >>> > > >>> The error, as shown in the attached ganesha-after-export.log.gz logfile, is the following: > > >>> > > >>> > > >>> 10/06/2015 02:07:47 : epoch 55777fb5 : node2 : ganesha.nfsd-26195[main] Bind_sockets_V6 :DISP :WARN :Cannot bind RQUOTA tcp6 socket, error 98 (Address already in use) > > >>> 10/06/2015 02:07:47 : epoch 55777fb5 : node2 : ganesha.nfsd-26195[main] Bind_sockets :DISP :FATAL :Error binding to V6 interface.
