That means any translation from NFS ops to GlusterFS ops happens internally in the Gluster NFS server process, without having to go through a mount point. -Shehjar > > 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.
