Hi, consider looking at this topic http://supercolony.gluster.org/pipermail/gluster-users/2014-September/018577.html . This guy made lots of test. It seems like 50 MB/s (or around 400 Mbps) is the theoretical maximal limit for replica 1. I am waiting for comments to this too. 2014-09-05 11:15

Isn't some of this covered by crm/corosync/pacemaker/heartbeat? Sorta, kinda, mostly no. Those implement virtual synchrony, which is closely related to consensus but not quite the same even in a formal CS sense. In practice, using them is *very* different. Two jobs ago, I inherited a design

Hi all, I've been trying to track down a bug that looks like data corruption coming from the Gluster FUSE client. I'm pretty new to Gluster, so perhaps there are better ways to get to the bottom of this. I have a distributed, replicated volume that was initialized as 3.5.1 and it has been

I have narrowed down the source of the bug. Here is an strace of glusterfsd http://fpaste.org/131455/40996378/ The first line represents a write that does *not* make it into the underlying file. The last line is the write that stomps the earlier write. As I said, the client file is opened in
