[Gluster-users] geo-replication master is distributed-replicated, slave is distributed only?

No restrictions about Volume type in Slave side. But when a Slave node
is down, some of the files already created are not accessible so data
operations/sync may fail for those files.(These errors will be logged
in Master log files and Geo-rep will continue.).

Other problem is deleting files in Slave side may get ignored silently
in Geo-replication because Geo-rep treats "ENOENT" errors as safe
errors during delete/unlink. (Safe error because, Geo-rep tried to
delete a file and that file gets "ENOENT"(No such file/directory)
error). Due to this Slave Volume may have files which are deleted in
master.
