Hello Ryan, glusterfs is not the same as drdb. We use it to replicate data from one node to the other and use corosync/pacemaker to do guaranty that one node is active.
I assume that you can never directly touch the R2, because there is a filesystem on R1 that is replicated to R2? Regards, Richard > Thanks for the reply, Richard > >I went to the site (gluster.org). It seems it runs the same way as DRBD. In >EMC's word, the primary storage is called R1 and replicate copy of the storage >is called R2. >DRBD is node A of the cluster accesses and controls R1. Node B of the cluster >accesses R2. That is what my understanding. Is gluster the same as DRBD? >HP's HPUX MC/ServiceGuard is both node A and B of the cluster access R1. >Normally node A controls R1. When it fails over, node B takes control R1 >(active/standby). Is there similar software exists? >Redhat's cluster is >similar but node A and B have control of R1 (active-active). > >Ryan _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://developerbugs.linux-foundation.org/enter_bug.cgi?product=Pacemaker
