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.

But ganesha failed to come up because RQUOTA port (default is 875) is already in use by an old ganesha instance or some other program holding it. The new instance of ganesha will die, but if you are using systemd, it will try to restart automatically. We have disabled systemd auto restart in our environment as it was causing issues for debugging. What version of ganesha is this?
