<pre>Hello Xavier,
it sounds pretty interesting to me.
Will you publish any news on this mailing list or is there another
place where I can update my self about your progress?

aren't the core developers of GlusterFS, but we are developing a new translator that will be able to implement something similar to a RAID6. In fact it will be able to have a configurable level of redundacy. A redundancy of 1 is equivalent to RAID 5; a redundancy of 2 is equivalent to RAID 6; and higher levels of redundancy are supported.

also trying to improve performance over replicate by using a new contention detection and locking mecanism, but no promises about that yet.

Not following. If you have a replica count of 3, you can lose two boxes in that group and still have access to all your data. It's more like a 3-way RAID-1 than anything like RAID-6. On 3/29/12 11:00 AM, Pascal wrote:

Coulson<<a href="mailto:david@davidcoulson.net">david@davidcoulson.net</a>[6]>: Hello David, thanks for your quick reply. I already considered a replica count of 3 (and six servers at all, correct?), but the problem would still be that two hard drives from the same "replica group" were not allowed to fail at the same time.

Not really 'RAID-6' comparable, but you can have two nodes fail without outage. <a href="http://download.gluster.com/pub/gluster/glusterfs/3.2/Documentation/AG/html/sect-Administration_Guide--Setting_Volumes-Distributed_Replicated.html">http://download.gluster.com/pub/gluster/glusterfs/3.2/Documentation/AG/html/sect-Administration_Guide--Setting_Volumes-Distributed_Replicated.html</a>[5]On 3/29/12 10:39 AM, Pascal wrote:

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 (<a href="http://gluster.org/pipermail/gluster-users/2009-May/002208.html">http://gluster.org/pipermail/gluster-users/2009-May/002208.html</a> [1], <a href="http://www.gluster.org/community/documentation/index.ph/Talk:GlusterFS_Roadmap_Suggestions">http://www.gluster.org/community/documentation/index.ph/Talk:GlusterFS_Roadmap_Suggestions</a> [2]). I would just like to have a scenario where two GlusterFS nodes/servers, respectively their hard drives, could fail at the same time. Thanks in advance!
