Looks like your configuration is from clumanager on RHEL 2.1 AS (there was no RHCS for RHEL 2.1). > This the hosts file /etc/host on the node1 (RAC1) > > # Do not remove the following line, or various programs > # that require network functionality will fail. > 127.0.0.1 localhost.localdomain localhost > # > # Private hostnames > # > 192.168.253.3 rac1.domain.net rac1 > 192.168.253.4 rac2.domain.net rac2 > 192.168.253.10 rac1 > [cluster] > alias_ip = 192.168.253.10 The cluster alias IP is only for monitoring, not for services. In any case, you need to have different hostnames for the cluster members, the alias IP, and any service IPs you intend to use. > [powercontrollers] > start powercontroller0 > IPaddr = rac1 > login = unused > passwd = unused > type = null > end powercontroller0 > start powercontroller1 > IPaddr = rac2 > login = unused > passwd = unused > type = null > end powercontroller1 Obligatory note: Please buy a power controller. > [services] > start service0 > checkInterval = 30 > start device0 > start mount > start NFSexports > start directory0 > start client0 > name = rac1 > options = rw > end client0 > name = /u04 > end directory0 > end NFSexports > forceUnmount = yes > fstype = ext3 > name = /u04 > options = rw,nosuid,sync > end mount > name = /dev/sdd4 > sharename = None > end device0 > name = nfs_project > preferredNode = rac2 > relocateOnPreferredNodeBoot = yes > end service0 > And when I launched this command on RAC2: > mount t nfs rac1:/u04 /u04 > It list the following error message : > Mount: rac1:/u04 failed, reason given by server: Permission denied > > Can someone help me to fix this problem in this configuration? a. Your /etc/hosts needs to be fixed: rac1 will first resolve to 192.168.253.3, so that server would refuse the mount. rac1 needs to be one IP, and the .10 address needs to have its own hostname. b. Your service needs its own IP address. I'd scrap the cluster alias IP and move it in to the service. c. You don't have RAC2 as a listed client in the service. So, if (a) wasn't true, mounting from RAC2 will always fail because it's not in the NFS ACL. Good luck! -- Lon -- Linux-cluster@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/linux-cluster
