Apostolos , Without knowing the true nature of the problem you wish to solve -- if you are looking to take a few embedded machines and build some kind of replicated distributed storage with gluster - the use of raw flash I don't quite understand -- you could use ramdisks on the targets and get speed, reliability and avoid component fatigue. https://lists.gnu.org/archive/html/gluster-devel/2013-05/msg00118.html -Nirmal -----Original Message----- From: gluster-users-bounces@xxxxxxxxxxx [mailto:gluster-users-bounces@xxxxxxxxxxx] On Behalf Of Apostolos Manolitzas Sent: Thursday, April 10, 2014 10:07 AM To: Ric Wheeler; gluster-users@xxxxxxxxxxx Subject: Re: linux flash filesystems and GlusterFS On 04/10/2014 03:16 PM, Ric Wheeler wrote: > On 04/02/2014 03:40 AM, Apostolos Manolitzas wrote: >> Hello all, >> >> I just discovered the GlusterFS while looking for a solution for high >> availability on our NAND flashes.

Thanks for the answer, I think we have to do some tests in order to have a clear view. -Apostolos _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://supercolony.gluster.org/mailman/listinfo/gluster-users _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://supercolony.gluster.org/mailman/listinfo/gluster-users
