Gluster ver: glusterfs-core/rdma/fuse-3.1.0-1 OS: Centos 5.5 x86_64 (Two VMWare Nodes) Hello All, I am relatively new to gluster, I've started diving into Gluster for a couple of weeks now. I was wondering if anyone is using Gluster with an email server, e.g. postfix or sendmail. I am curious to know on how fast gluster replicates files since MTA's do a lot of IO. I'd imagine some gluster tuning involved to handle a lot files needing to be replicated. Right now, I am testing out a 2 node setup, with one server replicating data to another node. One thing I noticed was when I created a file or directory on the server, the new data does not replicate to the other node. The only time data is synced from server to the other node is when I run "gluster volume rebalance test start". Is this normal? I had envisioned gluster would constantly replicate changes from the server to the other nodes, am I off base? The commands I used to create the volume from the server (hostnameA) 1) gluster volume create test replica 2 transport tcp hostnameA:/opt hostnameB:/opt 2) gluster volume start test 3) mount -t glusterfs hostnameA:/test /mnt My current volume info: Volume Name: test Type: Replicate Status: Started Number of Bricks: 2 Transport-type: tcp Bricks: Brick1: hostnameA:/opt Brick2: hostnameB:/opt Options Reconfigured: performance.cache-size: 6GB Greatly appreciate anyone has any pointers on how to improve replication.
