Each Gluster server that is going to also act as an NFS server (or Samba) has to mount the volume using the Gluster client: For example, on my two GlusterFS servers I have the following: LABEL=brick01-01 /export/nas-01/brick01 ext4 defaults,_netdev 0 2 LABEL=brick01-02 /export/nas-01/brick02 ext4 defaults,_netdev 0 2 ...bricks 3-8 LABEL=brick01-09 /export/nas-01/brick09 ext4 defaults,_netdev 0 2 localhost:/dev-storage /develop glusterfs defaults,_netdev 0 0 LABEL=brick02-01 /export/nas-02/brick01 ext4 defaults,_netdev 0 2 LABEL=brick02-02 /export/nas-02/brick02 ext4 defaults,_netdev 0 2 ...bricks 3-8 LABEL=brick02-09 /export/nas-02/brick09 ext4 defaults,_netdev 0 2 localhost:/dev-storage /develop glusterfs defaults,_netdev 0 0 And then "/usr/sbin/showmount -e nas-01" and "/usr/sbin/showmount -e nas-02" both show the "/dev-storage *" export. Also verify your firewalls have the appropriate ports open on all servers. For example on CentOS 5 for 2 servers with 18 bricks and 1 volume: # GlusterFS -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 111 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -m udp -p udp --dport 111 -j ACCEPT # GlsuterFS 24007, 24008 plus 1 port per brick across all volumes, 18 bricks in this case -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 24007:24026 -j ACCEPT # Gluster port 38465 and NFS for 2 Gluster servers, 1 port per server -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 38465:38468 -j ACCEPT # End GlusterFS Mike -----Original Message----- From: gluster-users-bounces at gluster.org [mailto:gluster-users-bounces at gluster.org] On Behalf Of Bernard Li Sent: Sunday, November 07, 2010 1:10 AM To: landman at scalableinformatics.com Cc: gluster-users at gluster.org Subject: Re: question on NFS mounting Hi Joe: On Sun, Nov 7, 2010 at 12:03 AM, Joe Landman <landman at scalableinformatics.com> wrote: > Actually, showmount didn't work. > > We get permission denied. ?Even after playing with the auth.allowed flag. That's an indication that the gNFS server is not running. I would recommend you review the FAQ and some of the recent posts on the list, as there have been a couple threads discussing numerous NFS-related issues and their solutions. I've collected them for you here for your convenience: http://www.gluster.org/faq/index.php?sid=679&lang=en&action=show&cat=5 http://gluster.org/pipermail/gluster-users/2010-November/005692.html Cheers, Bernard _______________________________________________ Gluster-users mailing list Gluster-users at gluster.org http://gluster.org/cgi-bin/mailman/listinfo/gluster-users
