[Gluster-users] Some questions about GlusterFS and Prod Environment
Good morning guys, we are going to deploy a new production infrastructure. in order to share some folders through our app servers (Tomcat 8), I wan to create a GlusterFS storage area. I made some tests in localhost (using some VMs), but at the moment only with Apache2. My configuration is a mirroring replica (1:1). *My questions are:* 1) Considering 2 Frontends and 2 Gluster FS Nodes, the best practice is to write a different fstab entry for each node? Frontend1 (mount the first gluster node, and the second one as backup volume): gluster1.droplet.com:/app_volume /var/www/html glusterfs defaults,_netdev,backupvolfile-server=gluster2.droplet.com 0 0 Frontend2 /etc/fstab (mount the second gluster node, and the first one as backup volume): gluster2.droplet.com:/app_volume /var/www/html glusterfs defaults,_netdev,backupvolfile-server=gluster1.droplet.com 0 0 2) I want to backup every day the volume files. I can run a zip command directly from the gluster node, or I need to mount it on the backup server than run the command? Is there any other good solution to store a backup? 3) Can I share WebApps folder between Tomcat servers? Is there any known issue? (for example putting a .war into the WebApps folder, I think I'll generate some errors due to tomcat war deploying? Anyone have experiences with tomcat and glusterfs shared folders?) 4) Can I use a load balancer software to mount GlusterFS volumes? If YES, is there any benefits? Thank you in advance for your answers, best regads, have a nice day, Riccardo ___ Gluster-users mailing list Gluster-users@gluster.org http://lists.gluster.org/mailman/listinfo/gluster-users
