I'm not following. There are actually two mounts on the system, Safe:/ccsa /mnt nfs noauto,bg,nodev,nosuid,proto=tcp6,vers=4.1 0 0 Safe:/ccsa/tahan/HD /home/ccsa/tahan/HD nfs noauto,bg,nodev,nosuid,proto=tcp6,vers=4.1 0 0 Both are affected. Submounts, such as, Safe:/ccsa/tahan/01_RSH 10269457792 777337088 9492120704 8% /mnt/tahan/01_RSH Are just because in the reality these are different ZFS volumes on the NFSv4 server and have their own exports.
