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.
My best to you,
~~Rick King
