Could please state directly in the docs that replica isn’t useful to make reliable R/W HA filesystems. There are a ton of web pages that suggest that gluster can be used to make HA filesystems, but that is false.[1]
It isn't. Consistency, availability, tolerance to network partitions. You get to pick any two.
To a normal person replica 2 means that it works when one goes offline. The problem is, if you configure quorums to avoid split brain, because you want a filesystem that works, then when the first replica pair goes offline, you get read-only errors on the filesystem. In the HA world, falling over dead, isn’t what people want. Not configuring a quorum is even worse, as then it isn’t even a reliable filesystem. Also, please state that by default, because of the quorum setting, the filesystem isn’t reliable when replica is used. Personally, I’d like a reliable high performance HA filesystem. I was hoping that gluster could be it. 1 - https://www.gluster.org/pipermail/gluster-users/2015-July/022843.html _______________________________________________ Gluster-users mailing list [email protected] http://www.gluster.org/mailman/listinfo/gluster-users
