[Gluster-users] Testing Gluster 3.2.4 in VMware

Tue Mar 11 09:50:43 UTC 2014

Hi Carlos, some good news.

After discovering with the df command that I was not mounting the server
I headed back to the books:
http://www.gluster.org/wp-content/uploads/2012/05/Gluster_File_System-3.3.0-Administration_Guide-en-US.pdf

It shows in section 6.1 how to get the latest gluster client. I was
using the wrong one:  3.2 . I need the latest 3.4.2.

Now I can mount the cluster from the client

$ df

cluster1:/gv0          16765952     33152  16732800   1% /mnt/glusterfs

I will test adding files and replication tomorrow.

Thanks for your help,

Dan
