Hello everyone, I would like to know if it is possible to setup a GlusterFS installation which is comparable to a RAID 6? I did some research in the community and several mailing lists and all I could find were the similar request from 2009 (http://gluster.org/pipermail/gluster-users/2009-May/002208.html, http://www.gluster.org/community/documentation/index.ph/Talk:GlusterFS_Roadmap_Suggestions). I would just like to have a scenario where two GlusterFS nodes/servers, respectively their hard drives, could fail at the same time.
The only way to achieve that kind of reduncancy (n+m) is by using something like Cleversafe with a cluster file system on top of it. Unfortunately, they have removed the free downloadable version of their software.
