[Gluster-users] Question about the behavior of Gluster regarding fencing a failed node
Hey, I am a new babies of Gluster, and found it is very useful, and many production usage. When setup our Gluster for some customer engagement project, a problem rising: Suppose that I setup my Gluster with Strip + Replica 2 on my 4 physical nodes, so I got replica setup with 2 nodes each. At this moment, one of node failed, thus cause replica as 2 broken, at this situation, what's the right behavior of Gluster? will it just use 1 remaining replica node to serve the service? or will it try to find another node to re-setup 2 replica nodes? Thanks! Xiaobin Zhang(???)

At least one node should be healthy in the replica pair to keep gluster volume online.> > > /Xiaobin Zhang(???)/ > /Cloud Solutions and OpenStack Development/ > /IBM China System and Technology Lab, Beijing/ > /E-mail: xbinzh at cn.ibm.com/ > /Mobile : 86-13910156791/ > /Address: Building 28(Ring Building), ZhongGuanCun Software Park, / > / No.8 Dong Bei Wang West Road, Haidian District Beijing > P.R.China 100193/ > > > _______________________________________________ > Gluster-users mailing list > Gluster-users at gluster.org > http://supercolony.gluster.org/mailman/listinfo/gluster-users-------------- next part -------------- An HTML attachment was scrubbed...
