We are encountering strange issues with symlinks in NFS-over-RDMA exported (ZFS backed) filesystems. We are using an Solaris 11.1 storage server to provide NFS-services to a number of CentOS6.4 clients. They are connected through Infiniband and using NFS-RDMA mostly works, except for the fact that symlinks are only readable/usable on the client on which the symlink was created. All other clients cannot access or follow the link.
Switching from RDMA to TCP "solves" the problem.
I found someone with the same issue on openindiana, but so far no answers on the list :
Has anyone on the list encountered this as well (and is there a fix?).
