I am new to glusterfs, and this list, please let me know if I have made any mistakes in posting this to the list. I am not sure what your standards are.
I came across glusterfs last week, it was super easy to set-up and test and is almost exactly what I want/need. I set up 2 "glusterfs servers" that serve up a mirrored raid5 disk partitioned into 3 5oogb partitions to 6 clients. I am using round robin DNS, but I also tried to use heartbeat and ldirectord (see details below). Each server has 2 NICs: 1 for the clients, the other has a cross over cable connecting the 2 servers. Both NICs are 1000mbps. There are only 2 issues. #1. When one of the servers goes down the clients hang at least for a little while (more testing is needed) I am not sure if the clients can recover at all. #2. The read/write tests I performed came in at 1.6 when using glusterfs, NFS on all the same machines came in at 11, and a direct test on the data server came in at 111. How do I improve the performance? ############################################### My glusterfs set-up: 2 supermicro dual Xeon 3.0 ghz CPUs, 8gb ram, 4 @ 750gb seagate sata HDs, 3 in raid5 with 1 hot spare. (data servers) 6 supermicro dual AMD 2.8 ghz CPUs, 4gb ram, 2 @ 250gb seagate sata HDs in raid 1. (client machines) glusterfs is set-up with round robin DNS to handle the load balancing of the 2 data servers. I also tried heartbeat with a virtual IP and ldirectord to redirect the traffic, but when I took down server 1, there was like a 10 second delay before server 2 took over the virtual IP and the client hung. -- ^C _______________________________________________ Gluster-users mailing list [email protected] http://gluster.org/cgi-bin/mailman/listinfo/gluster-users
