I would like to know if the linux nfs client included in current versions of the kernel supports fail-over to a replica on another nfs server, I am using (manually) synchronized read-only shares... I found very few information on Google about this topic and I suspect this is not implemented. I actually tried to setup this using SLES12SP1 (3.12.49 kernel) but I failed so far. I am not attached to this distribution/version in particular, just trying to see it working for real. ( I did some "rpcdebug -m nfs" session and it seems the fs_locations is not getting properly populated on my setup ) Any confirmation this should work or not would actually help me. THX. note from the exports man page: replicas=path@host[+host][:path@host[+host]] If the client asks for alternative locations for the export point, it will be given this list of alternatives. (Note that actual replication of the filesystem must be handled elsewhere.)
