Hi, I am currently testing GlusterFS and am looking for some advice. My setup uses the latest 3.4.2 packages from www.gluster.org SLES11-SP3.
I currently have a storage pool shared read-write across 2 gluster server nodes. This seems to work fine. However, I would also like to mount this pool on 4 further client machines running a legacy web application. Because of some limitations in the application, I would like to be able to tell these servers to mount the storage pool from one particular gluster server node, but to fail over to the second node if and only the first node becomes unavailable. I can mount the storage on the client nodes with both gluster nodes specified or with only one node specified but cannot see a way in the documentation of preferring one particular node and having the second node configured as a fail over. Is this possible? What am I missing? My current gluster vol file on my clients is as follows: volume remote1 type protocol/client option transport-type tcp option remote-host GLUSTER-01 option remote-subvolume /data/gv0/brick1 end-volume volume remote2 type protocol/client option transport-type tcp option remote-host GLUSTER-02 option remote-subvolume /data/gv0/brick1 end-volume volume replicate type cluster/replicate subvolumes remote1 remote2 end-volume volume writebehind type performance/write-behind option window-size 1MB subvolumes replicate end-volume volume cache type performance/io-cache option cache-size 512MB subvolumes writebehind end-volume And I have the following in the client's fstab: /etc/glusterfs/glusterfs.vol /opt/shared_files glusterfs rw,allow_other,default_permissions,max_read=131072 0 0 Thanks in advance for any help, Mike Peters _______________________________________________ Gluster-users mailing list [email protected] http://supercolony.gluster.org/mailman/listinfo/gluster-users
