I try to make unify & replicate gluster file system. I have 3 machine for 3server, 1client( 1 machine both server and client) machine 1?: server , client machine 2?: server machine 3?: server first, machine 1, 2 are configured to unify (I'm planning to use the algorithm nufa) then I conbined it with machine 3 to provide AFR by configuring replicate. but it can't operate properly here is my volume file. ________________________________ glusterfsd.vol volume strg type storage/posix option directory /data/export end-volume volume strglocks type features/locks subvolumes strg end-volume volume expdir type performance/io-threads option thread-count 8 subvolumes strglocks end-volume volume nspace type storage/posix option directory /data/namespace end-volume volume svol type protocol/server option transport-type tcp option auth.addr.expdir.allow * option auth.addr.nspace.allow * subvolumes expdir nspace end-volume ________________________________ glusterfs.vol volume server1 type protocol/client option transport-type tcp option remote-host 147.6.3.41 option remote-subvolume expdir end-volume volume server2 type protocol/client option transport-type tcp option remote-host 147.6.3.46 option remote-subvolume expdir end-volume volume server3 type protocol/client option transport-type tcp option remote-host 147.6.3.47 option remote-subvolume expdir end-volume volume client1-namespace type protocol/client option transport-type tcp option remote-host 147.6.3.46 option remote-subvolume nspace end-volume volume clients type cluster/unify option scheduler nufa option nufa.local-volume-name server1 option namespace client1-namespace subvolumes server1 server2 end-volume volume replicate type cluster/replicate subvolumes clients server3 end-volume volume writebehind type performance/write-behind subvolumes replicate end-volume It can mount glusterfs but, can not copy, remove, etc. Is this configuration possible?
